The Study Of River System Management Of The Taihu Basin During The Period Of The Republic

This article mainly analysis huaman factors in change of environment of Taihu basin from the late Qing Dynasty to the Republic of China. The water policy, conflicts of interests, land development and other issues to analyze water agency behavior and objective in the water affairs. Reclamation of lake water institutions for economic benefits,destroyed the lake environment, aggravated the natural disaster degree. Through the investigation on the above issues reveals the relation between human activites and river environmental change in Taihu.Taihu basin is composed of Tiaoxi River, Jing Xi, Wusong River, Huangpu River water composition, including southern Jiangsu and parts of Zhejiang Province, the history of this area is known as "Jiangnan region of river and lake". Superior hydrological environment of this area is formed in the transformation of human. The reservoir dam,sluice gate, the water conservancy facilities provide hydrological environment excellent for Taihu Basin. Since the modern times, the disrepair of water, Taihu River flood and drought occurres frequently, which lead to social unrest. This is the first part of this paper mainly views.The second part analyzes the deterioration of Taihu hydrological environment caused the error control strategy. Water conservancy institution to obtain benefits as the highest criterion control, change cultivation policy, the lake reclamation legalization, destroyed the hydrological and ecological balance. East Taihu flood drainge channel is greatly reduced,the flood control capacity of reducing flood risk increase. Lake excessive reclamation is the main cause of the frequent flood in Taihu River basin.The third part discusses the water management policy differences and induced changes in the environment. Gaochun County as water retention, sacrifice for maintaining economic stability ih the region of lower reaches of Taihu. Compareds with the rural water conservancy construction, the government is concerned about the drainage engineering of the city. Nanjing City Hall invest a lot of money for the sewer construction, waterproof ability to significantly improve.The four part of the study of conflict of interest of water agencies, as well as the change of management. In the early Republic of China, water conservancy institution is very much, but the mechanism of mutual accusation between. Enconuntering problems, no one is willing to solve it. After the flood of 1931, the national government unified hydraulic mechanism, strengthen the construction of water conservancy, water conservancy of Taihu basin are obciously improved.Needs to be pointed,after the flood,the national government has implemented a series of measures to promote water conservancy, the Taihu basin water resources development.The abolition of the polder and joint prevention measures to improve the water environment of Taihu Basin.The ability of preventing flood of the government has been greatly improved.The success prevention of Nanjing city flood in 1935 prevention that lack of human governance is a key factor of diasater in Taihu. The fifth part of this paper mainly discusses the water behavior of government.If you want to investigate the changes of water structure of Taihu Basin in a long time,there is also a need to limit downward to twentieth Century 60. There bad a bigger change environment of Taibu Basin in twentieth Century 60.The conclusion part changes on the water environment of Taihu basin are briefly described, in order to be able to grasp the changes in water environment as a whole.
