Speech on reservoir resettlement

Taiwan Province Province is located on the continental shelf of the southeast coast of China, from east longitude 1 19 18' 03 "to north latitude 124 34' 30" to 20 45' 25 "25' north latitude. Taiwan Province Province is adjacent to the Pacific Ocean in the east and the Ryukyu Islands in the northeast, about 600 kilometers apart; South of bashi channel, about 300 kilometers away from the Philippines; It faces Fujian across the Taiwan Province Strait in the west, with the narrowest point 130 km. Taiwan Province Province is the center of the western Pacific waterway and an important transportation hub for maritime links among countries in the Pacific region.

The Taiwan Province Strait extends from northeast to southwest, connecting the East China Sea of China in the north and the South China Sea in the south. It is about 200 nautical miles long and 70 to 22 1 nautical mile wide, with an average width of about 108 nautical mile. It is an important maritime traffic artery as well as an international maritime traffic artery. Ships traveling between the East China Sea and the South China Sea in China will pass through here. Ships from Europe, Africa, South Asia, Oceania and the eastern coast of China also pass through here. Ships from the Atlantic Ocean, the Mediterranean Sea, the Persian Gulf and the Indian Ocean to the Sea of Japan generally pass through here.

Taiwan Province Province includes Taiwan Province Island and 2/kloc-0 affiliated islands such as Lan Yu Island, Green Island and Diaoyu Island, as well as 64 islands of Penghu Islands, of which Taiwan Province Island covers an area of 35,873 square kilometers. At present, the so-called Taiwan Province Province usually includes Jinmen and Mazu islands in Fujian Province, with a total area of 36,006 square kilometers.

Taiwan Province Province is mountainous, with mountains and hills accounting for more than two thirds of the total area. The mountains in Taiwan Province Province are parallel to the northeast-southwest trend of Taiwan Province Island and vertically located in the central and eastern part of Taiwan Province Island, forming the topographic features of the eastern mountainous area, the middle hilly area and the western plain of Taiwan Province Island. There are five mountains, four plains and three great basin mountains on the island of Taiwan Province Province, namely, Central Mountain, Snow Mountain, Yushan Mountain, Alishan Mountain and Taitung Mountain, Yilan Plain, Jianan Plain, Pingtung Plain and Taitung Longitudinal Valley Plain, Taipei Basin, Taichung Basin and Puli Basin. The central mountain runs through the north and south, and Yushan is 3952 meters above sea level, which is the highest peak in East China. Taiwan Province Island is located in the Pacific Rim seismic belt and volcanic belt, with unstable crust and frequent earthquakes.

The climate in Taiwan Province Province is warm in winter and hot in summer, with abundant rainfall, and there are many typhoons and rainstorms in summer and autumn. The Tropic of Cancer runs through the central part of Taiwan Province Island, with subtropical climate in the north and tropical climate in the south. The annual average temperature (except in mountainous areas) is 22℃, and the annual precipitation is more than 2000 mm. Abundant rainfall has created favorable conditions for the development of rivers on the island. There are 608 rivers flowing into the sea alone, with fast-flowing water, numerous waterfalls and abundant hydraulic resources. Among them, the rivers with the length exceeding100km include Zhuoshui River (186.4km), Gaoping River (170.9km), Danshui River (158.7km) and Dajiaxi River (10).

The agricultural area in Taiwan Province Province accounts for about a quarter of the land area, which is rich in rice, with good quality and high yield in two or three seasons a year. The main cash crops are sucrose and tea. There are more than 90 kinds of vegetables, and the planting area is second only to rice. Taiwan Province Province is called "Fruit Kingdom", and there are many kinds of fruits. The output value of flowers is also considerable.

The forest area in Taiwan Province Province accounts for about 52% of the total area. Taiping Mountain in Taipei, Baxian Mountain in Taichung and Alishan in Chiayi are three famous forest areas, with 326 million cubic meters of timber reserves and nearly 4,000 species of trees, among which Taiwania flousiana, Castanopsis kawakamii, Cinnamomum camphora and Phoebe bournei are world-famous, and the output of camphor and camphor oil accounts for about 70% of the world total.

Taiwan Province Province is surrounded by the sea, with a total coastline of 1600 km. Because it is located at the intersection of cold current and warm current, fishery resources are rich. The eastern coastal waters are deep and the fishing ban period is endless; The western seabed is an extension of the continental shelf, which is relatively flat, rich in benthic fish and shellfish, and relatively developed in offshore fisheries and aquaculture. Offshore fishing is also relatively developed.

Taiwan Province Province is rich in water power, forest and fishery resources, but other natural resources are limited. Self-produced energy is only a small amount of coal and natural gas, and there are few metal minerals such as gold, silver, copper and iron, which are mainly stored in northern volcanic areas and central mountainous areas.

Since 1960s, Taiwan Province Province has attached importance to the development of industry, and has now formed an island-type industrial and commercial economy with processing and export as its mainstay. Industries include textiles, electronics, sugar, plastics and electricity. There are processing export zones in Kaohsiung, Taichung and Nanzi. North to Keelung and south to Kaohsiung, there are electrified railways and expressways, and air and sea routes can reach five continents.

In terms of administrative divisions, Taiwan Province Province is divided into two municipalities directly under the Central Government (level I), Taiwan Province Province (level I) 18 counties (level II) and five provincial-level cities (level II), and a regional joint service center equivalent to the provincial level has not been legalized. The original administrative divisions of Taipei, Yilan, Taoyuan, Hsinchu Miaoli, Taichung, Changhua, Nantou, Yunlin, Chiayi, Tainan, Kaohsiung, Pingtung, Taitung, Hualien and Penghu were divided into 16 counties. Taiwan Province provincial authorities designated Taibei in 1967 and Kaohsiung in 1979 as "the city under the jurisdiction of the Executive Yuan". In addition, there is a "Fujian Provincial Government" which governs Jinmen and Lianjiang (Mazu) counties.

There are Sun Moon Lake, Alishan, Yangming Mountain, Beitou Hot Spring, Tainan Chikan Tower, Beigang Mazu Tempel and so on.

Xiamen and Taiwan Province Province, facing each other across the sea, have a superior geographical position and a good deep-water port. Xiamen has been known as the "southeast gateway" since ancient times. Since the Song Dynasty, Xiamen and Taiwan Province Province belong to the same administrative unit, and mainland immigrants began to move from Xiamen to Taiwan Province Province. Similar geographical location, climatic conditions and living habits have communicated the close relationship and contacts between Xiamen and the people of Taiwan Province Province. As the Taiwan Provincial Government Records said, "Taiwan Province and Xiamen are like two wings of a bird, and local customs say that Xiamen is Taiwan Province and Taiwan Province is Xiamen". 70% of Taiwan Province people's ancestral home comes from southern Fujian, and the people of the two places are like brothers. This special geographical and historical relationship makes Xiamen a transit point and traffic artery for all kinds of exchanges with Taiwan Province Province, and also a concentrated place for economic and trade exchanges.

A hot and rainy climate

Taiwan Province Island is long and narrow from north to south, surrounded by a large watershed. The Tropic of Cancer just passes through the south-central part of the island, with subtropical climate in the north and tropical climate in the south. From the flat land to the high mountain, with the elevation rising, the temperature gradually decreases, forming the climate characteristics of heat, temperature and cold in the same time and space. At the same time, although the climate of Taiwan Province Province is strongly influenced by both the ocean and the mainland, the maritime climate is obvious, which is characterized by high temperature, rainy and windy on the whole.

Temperature and sunshine

The average annual temperature in the plains of Taiwan Province Province is 23.6 degrees Celsius. Among them, the average annual temperature in the north is about 22 degrees Celsius and that in the south is about 25 degrees Celsius. The average temperature difference between north and south in winter is about 5 degrees Celsius, but it is not much different in summer. The flat land in the province is long in summer and short in winter, while the southern part is long in summer without winter. After April every year, the average temperature is above 20 degrees Celsius for 8 months. The hottest June-September, the average temperature is 27-28 degrees Celsius. February 65438 to March of the following year is winter. The average temperature is above 15 to 16 degrees Celsius, and the average minimum temperature is higher than 1 1 degrees Celsius.

Influenced by the continental cold air mass, the northeast monsoon prevails in Taiwan Province Province in winter, but it is restricted by the warm current from the north to the equator. In summer, influenced by the Pacific subtropical high, the southwest monsoon prevails, and the southeast monsoon from the Pacific Ocean is blocked by the central mountain range.

The vertical variation of temperature in mountainous areas of Taiwan Province Province is much larger than that in the north and south, and the temperature decreases with the increase of mountain situation. In the mountainous areas of the northern region, the temperature drops by about 0.6 degrees Celsius at an altitude of 100 meters. In the south-central region, the temperature drops by about 0.5 degrees Celsius at an altitude of 100 meters. In winter, you can see snow at the peak above 3000 meters above sea level. The average annual temperature at the top of Yushan Mountain is only 3.8 degrees Celsius.

Taiwan Province Province is sunny. The annual sunshine hours in the plain area are 2 100 hours, the average sunshine hours in the central mountainous area are less than 1000 hours, the average sunshine hours in the north and south are 1500 to 1700 hours, the average sunshine hours in the central Taichung area are 2454 hours, and the average sunshine hours in the southern Tainan area are 26/kloc-0.

The high temperature and abundant sunshine in the plain area of Taiwan Province Province provide favorable conditions for the growth of various crops. Vertical change of mountain climate, vertical change of vegetation distribution, plant species. The annual sunshine hours in Taiwan Province Province are influenced by rainfall distribution and topography, and the number of high mountains is less than that of flat land. The average annual sunshine hours in plain areas are 2 1000 hours, while the average annual sunshine hours in central mountainous areas are less than1000 hours. The northern and eastern regions are less than the central and southern regions, with an average dimension of 65,438+0,500 to 700 hours, and the average in Taichung in the central region is 2,454 hours. Tainan in the south has the most 26 1.9 hours, while Yilan, Jijiang and Suao 1.400 hours in the north are the least.

Precipitation and temperature

Taiwan Province Province is one of the regions with the richest rainfall in China, with an average annual rainfall of over 2000mm, equivalent to 90 billion cubic meters of water, which is three times the average rainfall in the world.

The distribution characteristics of precipitation in Taiwan Province Province are as follows: precipitation in mountainous areas is more than that in plain areas; In the flat land, there are more marginal zones near the mountain than those far away from it; There are more plains in the east than in the west. The average annual precipitation in the central mountainous area is about 3000 mm, that in the flat land is about 1800 mm, that in the eastern flat land is between 1500-3000 mm, and that in the western flat land is the largest in Keelung in the north, with an annual precipitation of 3600 mm..

The rainless area in Taiwan Province Province is located in the west, south of Dajiaxi and north of Zengwen Reservoir, that is, the central and western parts of Jianan Plain. Among them, the average annual precipitation of Zhutang in Changhua County in 32 years exceeds 1 183mm, and that of Lugang 13 years does not exceed 1258mm.

The seasonal distribution of precipitation in Taiwan Province Province is closely related to monsoon and topography. There are obvious differences between the north and the south, and the seasonal changes of rainfall are also different. In summer, the southwest monsoon prevails, but the wind is weak, the temperature in various places generally rises, the water vapor in the air increases, the convection is strong, and there are many thunderstorms. Because there are many typhoons, it brings a lot of precipitation to the whole province. In winter (10 to March of the following year), the northeast monsoon prevails, and the cold air mass from the southern part of the mainland brings rich water vapor to Taiwan Province Island through the East China Sea, and the rainy season forms in the north and northeast, with precipitation accounting for about 60% of the whole year.

The rainy days in Taiwan Province Province are quite consistent with the annual precipitation, that is, there is more precipitation and more rainy days. The distribution characteristics of rainy days are: more mountains than flat land, more east than west, the whole island decreases from north to south, and the monthly precipitation changes from north to south. Precipitation intensity (precipitation per unit time) is generally higher in summer than in winter except Keelung in the north. Among them, the seasonal variation of precipitation intensity in the northern region is small, and the seasonal variation in the central, southern and eastern regions is large. Although there is abundant precipitation in Taiwan Province Province, there are still droughts in different degrees due to the differences in geographical and seasonal distribution. Although precipitation is the main source of water resources in Taiwan Province Province, abnormal precipitation often brings serious floods.

The relative humidity in Taiwan Province Province is relatively high, with little change, and the annual average relative humidity is mostly between 78-85%. In summer months, the relative humidity in other areas is above 80%, except in the northern part of Danshui, Keelung and Taipei. In winter months, the relative humidity in the eastern and southern parts of Taiwan Province Province is relatively low, about 75%, and it is far above 80% in other areas. The relative humidity in the central mountainous area has no obvious seasonal variation, and it is around 80% in all seasons.

Monsoons and typhoons

Taiwan Province Province is located in the contact zone between the Asian continental air mass and the ocean air mass, with monsoon all the year round and typhoon in summer, which has great influence on the climate of the whole island.

Taiwan Province Province is dominated by northeast monsoon in winter and southwest monsoon in summer. During the transitional period of northeast monsoon, southwest monsoon and southeast monsoon, the continental air mass and ocean air flow rise and fall with each other, and cyclones are active, bringing wind to Taiwan Province Province, which is called "transitional cyclone". Its wind direction is changeable, often forming whirlwind showers. When southwest winds prevail in summer, Taiwan Province Province is prone to tornadoes.

Taiwan Province Province is one of the areas that have been hit most by typhoons along the southeast coast of China. There are two main typhoon sources, one is a typhoon moving from the Pacific Ocean to the northwest via the east of the Philippine Islands, and the other is a typhoon moving from the north of the central South China Sea to the northeast. Every year, typhoon attacks begin in late April at the earliest and last for half a year, especially from July to September at the latest. Frequent typhoons often cause great losses to industrial and agricultural production and people's life in Taiwan Province Province.

Taiwan Province Province is characterized by a high temperature, rainy and windy climate, with relatively rich climatic resources such as light and heat, wind energy and water resources, which not only provide necessary conditions for the reproduction and growth of various organisms, but also provide favorable conditions for economic development, especially agricultural production.

The climate in Taiwan Province Province can be divided into seven types, namely, the warm and humid climate in the northeast, the warm and rainy climate in the west, the rainy climate in the southwest, the tropical rain forest climate in the east, the tropical monsoon climate in the southeast, the warm and humid climate in the middle and low altitude mountainous areas in the middle and the cold climate in the high mountain areas in the middle.

According to the local climate characteristics, the meteorological department of Taiwan Province Province divides the whole island of Taiwan Province Province into nine agro-climatic zones: northeast, northwest, Zhangzhong, Jia Yun, southwest, south, east coast, east mountain and central mountain, so as to give full play to the advantages of climatic resources in various places and avoid and reduce the adverse effects of adverse climatic factors on agricultural production.
