Jiangyin has a long history. During the Spring and Autumn Period and the Warring States Period, the land belonged to Yanling. It was once the fief of Ji Zha in Yanling, and later the fief of Huang Xie, the king of Chunshen. Therefore, it is known as "Yanling Ancient Town" and "Chunshen Old Seal", which has been recorded in writing for more than 2,500 years. In the second year of Jin Taikang (28 1), Jiyang County was established for the first time, and its administrative place was Hubei (there were two theories in the old annals: one was in Changshou Mocheng, and the other was in Yang Shezhen).
In the first year of Liang Shaotai in the Southern Dynasties (555), Jiyang County was abandoned and built at the foot of Junshan Mountain. Because it is located in the south of the Yangtze River, it is called Jiangyin County, which has jurisdiction over Jiangyin, Licheng and Liangfeng counties. In the first year of Chen Yongding in the Southern Dynasties (557), the local chronicles of Liang Wang were abolished and the county was changed to Jiangyin. In the third year of Tang Wude (620), Jiangyin County was established as Jizhou, with jurisdiction over Jiyang and Licheng counties.
In the first year of Song Chunhua (990), the Jiangyin Army was reset, which was repeatedly abolished. In the 13th year of Yuan Dynasty (1276), Jiangyin Army was promoted to Jiang Vagina and Governor's Office. In the second year of Hongwu in the Ming Dynasty, Jiangyin Prefecture was changed to Jiangyin County, which belonged to Changzhou Prefecture, and the evolution continued until the Qing Dynasty.
During the Republic of China, Jiangyin County was subordinate to Jiangsu Province. 194 1 year, the Communist Party of China (CPC) and the New Fourth Army under his leadership set up four county-level regimes, namely Jiangyin, Chengdong (also known as Yuxi), Chengxi and Shazhou, in Jiangyin Administrative Region and its adjacent areas.
April 22nd 1949 Jiangyin County belongs to Changzhou area of Sunan Administrative Office, February 6th1961(approved on June 29th 1957+0 1).
1983 65438+1October 18, Jiangsu Province has implemented a new system of city governing counties, and Jiangyin County has been placed under the management of Wuxi City. 1 On April 23rd, 987, with the approval of the State Council, Jiangyin County was revoked and Jiangyin City was established (Jiangyin City was formally established on August 23rd,1year).
Xu Xiake (1587 65438+10.5-16465438+8.3), whose real name is Hongzu and real name is Zhenzhi, is Xiake. He was a native of Jiangyin County (now Jiangyin City, Jiangsu Province), a geographer, traveler and writer in the Ming Dynasty. After 30 years of investigation, he wrote 65438. ?
Xu Xiake traveled all over his life, covering 2/kloc-0 provinces, municipalities and autonomous regions. "What a talented person has not achieved is unknown to others." Wherever he went, he explored seclusion, sought secrets, and recorded his travels, recording various phenomena, humanities, geography, animals and plants, etc.
The opening day of Xu Xiake's travel notes (May 19) was designated as China Tourism Day.
Personality influence
Xu Xiake also occupies an important position in the history of world science. As far as the scope of investigation is concerned, Xu Xiake is much larger than western scholars. Xu Xiake visited the tropical and subtropical karst developed areas in southwest China for three years, and the continuous distribution area of carbonate rocks in this area reached 500,000 square kilometers, ranking first in the world.
Western scholars' early investigation and discussion on karst landforms were almost confined to temperate karst areas in Europe and the Mediterranean, and the scope of investigation was far less than that of Xu Xiake. As far as time is concerned, Xu Xiake is much earlier than western scholars:
It was not until 1845 that German traveler Rong Xun described the terrain of Showa "Qian Shan", which was more than 200 years later than Xu Xiake. Jaafar's "Underground World" (the remaining draft) in the French National Library in Paris involves cave investigation, but it contains a strong mysticism, ten years later than Xu Xiake.
Warva Sow's "The Honor of Duke Klein" describes caves and sinkholes in his hometown and neighboring areas. Published in 1689, half a century later than Xu Xiake, it is still mysterious. Stalactites are discussed in On Strata by Russian scientist lomonosov (1763), which is later than Xu Xiake 130 years.
