Did Zheng He pass Baguazhou on his voyage to the West? Is there a detailed description? thank you

Baguazhou is located in the middle reaches of the Yangtze River in the northern suburb of Nanjing, facing Yanziji in the south and Liuhe District in the north across the river. Because it looks like straw sandals, it was once called Straw Shoes Island. By the end of the Qing Dynasty, due to the merger with another Qilizhou, it gradually became a kind of gossip, and it is even more famous today. Baguazhou is located in the middle reaches of the Yangtze River, 4 kilometers downstream of Nanjing Yangtze River Bridge. It is the third largest island (Jiang Xinzhou) in the Yangtze River after Chongming and Yangzhong.

Baguazhou faces Nanjing's main urban area in the south, Liuhe District in the north, Xinshengwei Foreign Trade Wharf in the southeast, and Pukou District in the west. It is located in the urbanization zone of Nanjing metropolitan area, which takes the river as the axis and develops along the river. Through the connection of the Second Nanjing Yangtze River Bridge, Baguazhou can be connected to National Highway 328 in the north, Shanghai-Nanjing Expressway in the south, National Highway 3 12 and Huancheng Road. Baguazhou covers an area of 55.62 square kilometers and has a population of nearly 33,000. There is an administrative town on the island, which belongs to Qixia District of Nanjing. The overall planning of tourism development in Baguazhou includes the whole island of Baguazhou and its adjacent Yangtze River waters.

Baguazhou

As the third largest Jiang Xinzhou in the Yangtze River, Baguazhou has a low-lying mainland with a ground elevation of 5.2-7.7m (Wusong elevation), most of which are below 6.5m, and the parts above 6.5m are mainly distributed on both sides of small rivers in the northwest of the mainland. The mainland topography is generally slightly higher in the northwest and slightly lower in the southeast. Baguazhou belongs to the subtropical monsoon climate zone, with four distinct seasons, warm and humid, and concentrated rainfall. The rainfall process mostly occurs from June to September, with annual average rainfall 1 000-100 mm, annual average temperature 15.4℃ and monthly average temperature1.

Baguazhou specialty

The soil and climate conditions in Baguazhou are especially suitable for the growth of various crops, especially for the cultivation of wild vegetables. After years of development, Baguazhou has become the largest production base of "Wild Eight Fresh" in Jiangsu Province. The beaches along the Yangtze River around Baguazhou belong to primitive wetland environment, with typical biodiversity characteristics, in which waterfowl such as egrets, wild ducks and water hyacinths grow freely. In addition, rabbits, pheasants, hedgehogs, snakes and pythons also haunt the continent. Common birds include turtledove, thrush, starling, red-billed finch, grey magpie and wild goose. Precious finless porpoises are also common on the surface of the Yangtze River around the mainland. The Yangtze River is divided into two branches in Baguazhou, with the south branch as the mainstream with the maximum water depth of 35m and the north branch as a tributary with the maximum water depth of about 10m. According to the hydrological data provided by Nanjing Yangtze River Station of Jiangsu Provincial Water Resources Department, the lowest water level of the Yangtze River is 1.54m, and the highest water level is 10.22m (Wusong elevation). There are two levees around Bagua Island, primary and secondary, most of which are outside the river bank, which can resist general floods. The flood wall top elevation of the main dike is12.0-12.5m, which can resist the once-in-a-century flood. The surface water system in Baguazhou is developed, with various ponds of 9.744 km2, accounting for 17.5% of the total area of the whole continent, including 3 large ditches, 29 medium ditches and more than 300 small ditches. The mainland has shallow groundwater level and good groundwater recharge conditions.

Edit the pastoral features of this paragraph.

At present, Baguazhou still maintains the natural pastoral characteristics based on agricultural economy. Compared with the bustling and noisy urbanization areas around, there are more green vegetation, fresh air and quiet environment here. The water system in the continent is criss-crossed, the fields are criss-crossed, and chickens and dogs are familiar. It is a rare "Xanadu" in Nanjing metropolitan area. Its southwest Zhoutou faces the Mufu Mountain and Yanziji in the south of the Yangtze River across the river, overlooking the Nanjing Yangtze River Bridge in the upper reaches and the Nanjing Yangtze River Bridge nearby, making it an ideal place to enjoy the magnificent scenery of the Nanjing River.

Edit the history and culture of this paragraph.

Baguazhou

The history of Baguazhou can be traced back to the Southern Song Dynasty. According to textual research, Huang Tiandang, the famous anti-gold campaign in the Southern Song Dynasty, was located in the lower reaches of Qingzhou (the prototype of Baguazhou), and today's Baguazhou evolved from Qingzhou in the Southern Song Dynasty. In A.D. 1684 (the 23rd year of Qing Emperor Kangxi), sporadic immigrants began to live in the southwest corner of Baguazhou (called Qilizhou), and in A.D. 17 12, villagers began to reclaim land on the mainland. According to the records of villagers' anti-hegemony tablet in Baguazhou, this place was under the jurisdiction of Shangyuan County in 17 18 (the 58th year of Kangxi), indicating that Baguazhou and its residents have been included in the official household registration management. In A.D. 175 1 year (the 16th year of Qing Qianlong), Emperor Qianlong boarded Yanziji, and wrote a poem entitled "I only like flying sand to become a green field, and the kitchen smoke village is safe for a long time", in which "green field" refers to Baguazhou, and "kitchen smoke village ploughs" indicates that a considerable number of villagers lived in Baguazhou at that time. According to textual research, the name of Baguazhou has a history of more than 300 years. There are two opinions about the origin of the name of Baguazhou: one is named after the shape of "Bagua"; There is also "Ming Taizu's Ma Huanghou lost the gossip jade in the middle of the river, which formed the gossip island" (a folk legend circulating on gossip island). In A.D. 1927 (Republic of China 16), after the establishment of the National Government, Baguazhou was incorporated into the urban area of Nanjing. At that time, there were more than 3,000 Banners in Nanjing, and Baguazhou was the land reclaimed by Banners. Later, a large number of poor people from Wuwei, Anhui Province and Pixian County, Jiangsu Province moved to Baguazhou, and Baguazhou, where reeds were everywhere, became the place where they cultivated and settled. Today, the population of Baguazhou is nearly 33,000, and the cultivated land area is nearly 60,000 mu. 1April 23, 949, Nanjing was liberated, and Baguazhou belonged to the eighth district of Nanjing. The whole continent is divided into five towns: Shangba, Zhongqiao, Xiaba, Li Xun and Qili. 1952 was placed under the jurisdiction of Liuhe County, and Baguazhou District was established, with five original towns; 1956 returned to Nanjing and belonged to Yanziji District. The original five townships were merged into three townships: Shangba, Xiaba and Qili. 1958 10 was placed in the suburbs of Nanjing, and the original three townships merged to form the Baguazhou People's Commune; 1960 was included in Xiaguan District of Nanjing; 1961May was incorporated into Pukou District of Nanjing; July 1962, assigned to Yanziji District, Nanjing; 1963 was placed in Qixia district of Nanjing in July, and Baguazhou was divided into five people's communes, namely, Shangba, Zhongqiao, Xiaba, Li Xun and Qili, and merged into one people's commune in May. 1965. 1June 983 baguazhou people's commune was changed to baguazhou township; In 2002, Baguazhou Township was changed to Baguazhou Town with 12 administrative villages.

Baguazhou

Baguazhou is located at 3010 north latitude and118 49 east longitude. It belongs to the subtropical monsoon climate zone, with four distinct seasons, mild and humid climate and concentrated rainfall. Annual rainfall1000 ~1100 mm, and the rainfall process mostly occurs from June to September. Baguazhou is a sandbar plain in the middle of the Yangtze River formed by scouring and silting. The potential in the mainland is low and flat, showing a pattern of slightly higher northwest and slightly lower southeast. The Yangtze River is divided into two branches in Baguazhou, with the south branch as the mainstream with a maximum water depth of 35m and the north branch as a tributary with a maximum water depth of about 10m. There are two levees around Baguazhou, a first-class levee and a second-class levee. The flood wall of the main dike can defend the once-in-a-century flood, and the top elevation of the flood wall is12.0-12.5m.. Baguazhou has a developed surface water system and dense ponds. There are 3 large ditches, 29 medium ditches and more than 300 small ditches in the continent, and the water surface of various ponds is 9.744km2, accounting for 17.5% of the total area of the whole continent.

Edit the atmospheric environment in this section

According to the special study of Nanjing Institute of Environmental Science, the atmospheric environmental quality of Baguazhou has not changed significantly in the past five years, and the conventional pollution factors (SO2, NO2, soot) can meet the requirements of functional areas stably.

Edit this section water quality monitoring.

Baguazhou

Except nitrogen and phosphorus, the monitoring indexes of water body can basically meet the Class IV water quality standard of surface water. Except for petroleum and nonionic ammonia, the water quality of the half river around Baguazhou has exceeded the standard, and other monitoring indicators have not exceeded the Class II standard of Environmental Quality Standard for Surface Water (GB 3838-88). Except for the total number of coliforms and bacteria, other indicators of groundwater quality monitoring can meet the Class III standard of Groundwater Quality Standard (GB/T14848-93). The total number of coliform bacteria and bacteria can only meet the standard of class V, so the groundwater in Baguazhou is not suitable as the direct drinking water source for residents. The acoustic environment meets the corresponding requirements of the Standard for Environmental Noise in Urban Areas.
