錢塘江流域城市飲用水水源公共安全對(duì)策研究
[Abstract]:In recent years, more and more attention has been paid to the safety of urban drinking water sources in Qiantang River Basin. For example, in Hangzhou, first, the comprehensive renovation of the Qiantang River drinking water source was carried out, and then the construction of the project using the Yulin Reservoir as a reserve reservoir was initiated. Then the drinking water project of Xinanjiang River is included in one of the key projects of investment and construction of water conservancy projects in Hangzhou during the 12th five-year Plan. It can be seen that the safety situation of drinking water source in Hangzhou main urban area is serious. How to ensure the safety of drinking water source in order to ensure the sustainable development of Qiantang River Basin is a subject that needs to be studied in depth. This paper studies the historical changes of urban drinking water in Qiantang River basin from a long-term perspective by combing the domestic and foreign relevant research results, existing laws and regulations, and the management system for the first time. In order to solve the problem of drinking water safety in this basin, the urgent task is to set up the water resources management institution and construct the public safety system of drinking water source in Qiantang River basin from the point of view of the integrity of the basin. First of all, this paper found that the urban drinking water and the way of water supply have undergone three major changes: first, the main drinking water is river water (stream water, river water), well water, lake water as the main drinking water; The second is the centralized water supply with the river water as the main raw water, and the third is the centralized water supply with the reservoir water and the water from the Xinan River, the Fuchun River and the Qiantang River as the raw water. The three vicissitudes are closely related to the economic and urban expansion of the basin, the change of residents' living space and life style, and the increasingly serious water pollution. Secondly, this paper points out the main problems faced by urban drinking water sources in this basin: one is the problem of raw water of drinking water, the other is the allocation of water resources, the third is the pollution of water source environment, the other is the problem of water resources allocation. The fourth is the ecological compensation mechanism of the water source area; the fifth is the sudden water crisis; the other is the watershed management system. Finally, this paper puts forward countermeasures from four aspects to solve the problem of urban drinking water safety in this basin: first, learn from the experience of watershed management in the United States, Britain and some European countries, and start from the integrity of the basin. Break the administrative division management authority, perfect the Qiantang river basin water resources management system, propose to establish the Qiantang river basin water resources committee or adjust the existing Qiantang river administration function, establish the long-term management response mechanism; The second is to construct a public safety system for drinking water sources in the Qiantang River Basin, to build a public safety database for drinking water sources, to cultivate the concept of sustainable public safety for residents, and to further improve the legal system for the protection of drinking water sources in the Qiantang River Basin. The fourth is some specific problems that need to be solved urgently at present, including the construction of standby water source, the treatment of environmental pollution of drinking water source, the industrial structure planning of Qiantang River basin, and so on.
