The Environmental Benefit Analysis About Attifical Oasis Of Jingtai Electric Power's Pumping Irrigation Project

Jingtai electric power's pumping irrigation is the biggest pumping irrigation project in our country, being been included in "China most" . The engineering settles more than 30 myriad immigrate including Jingtai, Gulang, Dongxiang, Yunjing, Huining, Tianzhu, InnerMongolia left ensign etc.7 counties,promoting the whole provinceses development. The social public-spirited business had a big development,in former days unpopulated Yitiao mountain have become the center of the politics,economy. Cultural interaction in the county now,the high building rises straight from the ground ,the business net orders numerous and densely spread out, the post and transportation on all sides radiates, gathering city trade more active, culture,education and health business booming development. But in Jintai Pumping Irrigation area many people engage in farm production,the region has been already set up or is setting up a production base of grain and production bases of animal agriculture, melons and fruits gradually. So the substance of the socienty economy in Jingtai irrigation district is an artificial oasis economy, because the artificial oasis is placed in dry environment, its ecosystem system is weaker, turning toward erosion easily it is the opposition of the oasis. Therefore following natural regulation and proceeding proper implement of artificial oasis sustainable development in the light of local conditions will be the only road of Jingtai pumping irrigation district. Resarching deeply the ecosystem environment and the development of the society economy about Jingtai pumping irrigation district,drawing up reasonable and viable way of thinking and programming to provide for the development of aftertime basis.This text analyzes the ecosystem environment of Jingtai irrigation district turns for the better gradually of trend since irrigation and the artificial oasis obtains the social and economic performance in the meantime,according to the area artificial oasis circumstance variety and its development trend in last years. but irrigation distric still exist some problems. Combine a local actual circumstance according to this, building up Jingtai irrigation district valuation system of the artificial oasia sustainable development and valuate it,then put forward some suggestions. The system analysis to the environment effect of artificial oasis according to the weather, water and the soil. Analyzing the variety circumstance of climate more than 40 in the last years including humidity,temperature,rainfall,wound velocity, evaporation. The result is that the weather of Jingtai irrigation district is advantageous to go to the self-protective direction. It can resist a sandstorm very availably in the meantime,maintain one cool and moist environment for local people,analyzing the water date of mang years in the last years. We can know local earth's surface water path increase and the underground water level rises gradually .Though the groundwater quality is worse, there is the trend of gradual amendment. The convert among plants , Gobe and desert and the change of soil salt explain the soil environment has been already greatly improved. Dry index and ecosystem environment quality is been used to evaluate the total effect of local ecosystem environment, Analyzing can get the result that the artificial oasis ecosystem environment go toward the direction development which is advantageous to plant growth and mankind's existence.The ecosystem environment is the foundation of the mankind social development, but the economic construction is the mankind motive and target of the social development, Jingtai irrigation district development not only resist and win a bad natural environment, in the meantime raising agriculture productivity, aroused the second industry and the development of the third industry, people living head into first step wealthy from the middle-class family, the economic and social development have already followed industrialization mediumly, attaining initial modernization index, obtaining the good economic foundation of constucting the ecosystem city.Combine the natural characteristics of the artificial oasis and local actual circumstance, making use of the method of system analysis, building up the index system of the sustainable development valuation of Jingtai irrigation district artificial oasis,there are three aspects including social economy,resources environment and location condition. Make use of line also not line theories to build up valuation mathematics model of development,deciding adjudicate standard through comprehensive adjudicate method,and carry on valuation analysis on current artificial oasis of the Jingtai irrigation district. Put forward the suggestion that the artificial oasis of Jingtai irrigation district will be developed:take agriculture as mother to develop modern agriculture actively,develop industry properly, strengthen tour industry;We should penetrate the thought and the technique of sustainable utilization about the natural resources environment which take water resources as nucleus.
