Abstract


Xiaoqing River originated from MuLi Zhuang, Jinan. In history it was a man-made canal and played an important role in flood protection, drainage, irrigation, shipping, landscape and so on. Since 70’s of last century, along with the step out of industrialization and urbanization, the excessive emission of industrial and domestic sewage has led to water pollution of Xiaoqing River Basin in Jinan, a serious deterioration of ecological environment, which have had a bad impact on economic development of Jinan City and areas along the river basin. The source treatment is the key to achive the goal of fundamental governance and comprehensive renovation. Inter-basin Water Transfer will make up the water resources shortage problem of its own. It is an important measure to adjust the spacail and tempoarl uneven distribution of regional water resource. Water environment of Xiaoqing River can be significantly improved by water transfer, which also promotes economic development of areas along the river basin.As a part of the project of water dirversion to Xiaoqing River, the thesis includes two parts: the analysis of available water supply and fuzzy comprehensive evaluation. By comprehensive analysis of each scheme around Xiaoqing river, Dong-ping lake, Yufu River and the Yellow River are considerd as three avaliable project.Considering the situation of each water supply scheme, it could be calculated by different method based on the principle of reservoir profiting regualtion, which use VBA program to calculate the guarantee rate of water supply. The result shows that the scheme of Dongping Lake and Tianshan can meet the 300,000 cubic meters daily water demond of Xiaoqing River, while Wohu shan scheme can only supply 50,000 cubic meters a dayThen, considering the advantages and disadvantages of each water supply scheme, the thesis determine eight evaluation index which includes available water supply, source water price, quality, matching engineering cost, operation management cost, management system, sediment concentration, landscape effect. Based on the index system and fuzzy evaluating model, which combines the analytical variation coefficient method and index neighboring comparative method to calculate the weights of each index, the most practical conclusion of the water diversion project to Xiaoqing Rriver is achieved. The result shows that Dongping Lake is the optimum scheme, Tianshan is the next, Wohushan is the wosst scheme.The project of inter-basin water transfer for ecologic water compensation of Xiaoqing River is first put forward in this paper, which also evaluate each project objectively. The result provide reference for the management department of Xiaoqing River, and it also has some realistic significance and application value.
