Research On Water Resources Argumentation Of GuanLu Reservoir In Qing Dao City

Qingdao is a city one of the serious water shortage cities in northern China,With the city's rapid construction and socio-economic development,the contradiction between supply and demand of water resources become more and more serious, water resources has become key constraints of economic and social sustainable development in Qingdao City.On the basis of the principle of finding new water resources and reducing expenditure simultaneously,giving the priority to the latter,using the fundamental theory on inter-basin water transfer,water saving and rational allocation of water resources,considering the year 2015 as near-term horizon year,the year 2030 as long-term horizon year,my thesis analyses and estimates present states of water resources and its exploitation and utilization of Qingdao,and also construes the relationship between water resources supply and demand.Based on the analysis of utilization of the existing water sources,usage of sea water and reuse of waste water, the paper makes an verification of riverhead of the project of water diversion from yellow river to Qingdao,supply sources of Dagu river and Changjiang river through the South-to-North Water Transfer Project.The paper analyzes the feasibility of tapping potential of the project of water diversion from yellow river to Qingdao from the point of view of water resources.The results suggest that the potential can greatly alleviate the conflict between the water resources supply and demand of Qingdao,and the conclusions are as follows:1.On the basis of the investigation and analysis of the existing conditions of water uses,on the principle of giving priority to water saving,operating water projects optimally and allocating water resources rationally,the paper makes a water resources supply and demand balance analysis for different horizon years.The results show a water deficit of 133 million m~3 in 2015 and 221 million m~3 in 2030.in order to solve the problem,exploitation of the water resources potential efficiently and construction of the inter-basin water diversion project are very necessary. 2.Data series of 1980-2006 of Lijin hydrology station are applied to analyze Yellow River flow and available water amount to be diverted.In case of P=95%,the available water amount to be diverted is 245 million m~3 in the period of September to March in the next year.As some Yellow River water diverted to Jiaodong,it is difficult to increase water supply for Qingdao from Yellow River.3.Water diversion from Dagu river is verified.The river basin is divided into computation units based on sizes of water resources projects,tributary location and its administrative divisions.Results of runoff regulation computation show that 4.6 million m~3 of water quantity may be diverted from Dagu River in case of p=95%.4.Multiple scenarios are analyzed for operation of GuanLu reservoir.It is necessary to recover the project of GuanLu reservoir.5.The rehabilitation of the project of GuanLu Reservoir will produce great environment benefit but no adverse effect on water resources condition and other water users.The paper makes qualitative analysis on uncertainties and risks for water demand and supply forecast and so on to improve the security of city water supply and the social and economic sustainable development of Qingdao.
