Study Of Exploitation And Utilization & Protection Of Water Resources And Water Environment In Linzhang Hebei

Water is the lifeline of human being's existence and development, the lifeline of national economy and ecological environment, and also important material base of realizing the sustainable development. The water resource management is the key to solve the global water crisis and the impoverished question, the Chinese water management reform strategy should change from " take the engineering construction as the center " to the "take the system construction as the center", the water resources and the water environment synthesis management, manifestses precisely this strategic concept. This management pattern has not been used in the past in our country, also is a major problem in the world, the Asian-Pacific area and China urgently await to be solved.Water is lack in Linzhang Country of Hebei Province.

They mainly include: usable surface water reduced, water environment worsen; groundwater overdraft; secondary soil saline and alkali spread;lack management of water resources and water environment, poor consciousness on management. So the study of the exploitation and utilization and protection of water resources in Linzhang Country has realistic significance for the water resources sustainable development.The study is on the base of the Water Conservation Project financed by the World Bank and GEF Haihe River Project in Linzhang. The major contents include: firstly,water supply-demand balance is analyzed in Linzhang Country based on the present evaluation of water resources and water environment and management status; secondly, the paper researches water use efficiency and poses a series of problems from water saving in agricultural, industrial and urban domestic uses; thirdly, a series of countermeasures are presented on the basis of investigation of point and side pollution sources and water environment status; fourthly, the calculation and analysis of ET value is made with ET technology. Using ET value allocated the rights of water resources in Linzhang Country. Control groundwater extraction, make groundwater extraction in the years reach an average dynamic equilibrium and achieve sustainable use of water resources.
