Answer: b

2. Specialization in agriculture

American agriculture has realized the specialization of regional production, and the output and export of many agricultural products rank among the top in the world, making it a world agricultural power.

(1) The natural conditions for developing agricultural production are superior.

① position

The vast majority of the United States is located in the north temperate zone, with sufficient heat, which is conducive to agricultural production.

② Topography

The terrain of the United States is columnar in north and south: the high Cordillera Mountains in the west, the vast plains in the middle and the low Appalachian Mountains in the east.

The United States is dominated by plains, accounting for more than half of the country's total area. Cultivated land is vast, accounting for about 10% of the world total area. Fertile soil is conducive to agricultural development.

③ Climate

The United States has a temperate continental climate, the southeast coast has a subtropical monsoon humid climate, the west coast has a temperate maritime climate and a Mediterranean climate, the west has a plateau mountain climate, and the southwest near Mexico has a tropical desert climate.

The precipitation in the United States gradually decreases from the southeast coast to the northwest. The precipitation in the eastern part of the Rocky Mountains is more than 500 mm, and the water condition is good, which is beneficial to agricultural production.

④ Rivers and lakes

Great Lakes: Located at the junction of the northern United States and Canada, it is the largest freshwater lake group in the world.

Mississippi River: Located in the middle of the United States, it is the fourth longest river in the world and the largest river in the United States.

Lake Superior is the largest freshwater lake in the world.

The Mississippi River and the Great Lakes provide good conditions for irrigation and shipping.

(2) Specialized production in agriculture.

American agricultural production makes full use of the natural conditions in different regions, realizes the specialization of regional production, and forms some agricultural belts (regions). The names, distribution and causes of some agricultural belts (regions) in the United States are shown in the table below.

Regional origin of agricultural belt (region)

The Great Lakes with higher latitude and the northeast region of dairy belt are located in the north, and the climate is cold and humid, which is suitable for pasture growth. The manufacturing belt in the United States is densely populated with cities, and the market demand for milk, meat, poultry and eggs is great. These products are not easy to store and transport for a long distance, so they are located near the market.

The central plain of corn belt is flat and fertile, which is beneficial to mechanized production; At the same time, it is suitable for the growth of corn, and corn can also be used as feed for nearby dairy belts.

The northern and central parts of the central plain in the wheat-growing area are flat, with fertile black soil, and the high temperature period is consistent with the rainy period, which is suitable for wheat growth.

Cotton belt in America 35&; South of degN, the terrain is low and flat, the latitude is low, and the heat is sufficient, which is suitable for cotton growth.

The subtropical crop belt has low latitude, abundant heat, abundant precipitation and low terrain, which is suitable for the growth of subtropical crops.

Animal husbandry and irrigated agriculture areas The mountainous areas in the western United States have higher terrain and less precipitation, so we can only develop animal husbandry and irrigated agriculture.

① All processes and links of agricultural production in the United States have been mechanized and specialized, with high efficiency and large output.

American agriculture is very dependent on the international market and often faces the problem of surplus agricultural products. Environmental pollution and the destruction of ecological balance have caused many "black storms".

Song remembers the agricultural belt in the United States: south cotton is irrigated to the north and west, with a corn belt in the middle and wheat planted on both sides of the corn. Note: "cotton" refers to cotton belt, "milk" refers to dairy belt, and "irrigation" refers to animal husbandry and irrigated agricultural areas.

Example 2- 1 A ship full of goods returned from the ocean and docked at new york Port. The unloading workers said they were all agricultural products. Please guess which of the following agricultural products is most likely? ( )

A. Corn B. Soybean C. Tobacco D. Tropical agricultural products

Analysis: The United States is mainly located in the north temperate zone, which is suitable for the growth of temperate crops. The output and export of corn and soybean are among the highest in the world, and a large number of tropical agricultural products, such as coffee, cocoa, bananas and natural rubber, need to be imported. So the agricultural products shipped to new york may be tropical agricultural products.

Analysis: The key to this problem is to understand the relationship between the distribution of American agricultural belt (region) and geographical location, climate and topography. The United States is surrounded by the sea on three sides, the Pacific Ocean in the west, the Atlantic Ocean in the east and the Gulf of Mexico in the south. The distribution of agricultural belt in the United States can be simply summarized as "south cotton and west milk irrigation, corn belt in the middle, and wheat planted on both sides of corn". The picture shows that American agriculture is characterized by regional production specialization, with the advantage of making full use of natural conditions in different regions, using agricultural machinery on a large scale, facilitating the adoption of advanced science and technology and improving production efficiency.

Answer: (1) Pacific Atlantic Gulf of Mexico

(2) Corn belt, cow belt and cotton belt in the mixed farming area of animal husbandry wheat area and irrigated agriculture area.

(3) Regional specialties can make full use of natural conditions in different regions, use agricultural machinery on a large scale, facilitate the adoption of advanced science and technology, and improve production efficiency.
