Study On Rational Allocationg Of Water Resources In The Tarim River Basin

The water resources is the material base which the human survival and the economic society develop, is the unreplaceable important natural resource. Tarim River is our country longest arid area diffusion inland river, in recent years, the basin water pollution was serious, the downstream ecological environment worsened, might supply the humanity to use the use the water source to be day by day short.After studying the ecology water distribution, the downstream subsoil water level change and the vegetation biology growth as well as fill the change relations, indicated that the subsoil water level rise, the water quality changes for the better, promotes the region ecology to resume the construction.The selection appraisal factor, uses the fuzzy quality synthetic evaluation method, produces the class area water resources bearing capacity to the Tarim River basin to make the appraisal. The findings indicated that the Ksu area was the water resources load bearing burden overweight area, the Kezhou area, the Bazhou area and the Hetian area still had the water resources to develop the space.Using system of rating computation appraisal area water resources balance between supply and demand, analysis basin forecast appraisal area in 2010 scarce form, finally indicated that in 2010 appraises the area to be possible still permissible to satisfy the domestic water using the water resources total quantity. But relative ecology water used slightly obviously insufficient.The long-term murky water used price is creates the agricultural water waste the main root. Through to appraise the area 5 place state 15 agriculture irrigation sampling point the data analysis, indicated that the complete cost sailor and the agriculture irrigation water has the relevance. Is bigger than 0.34 Yuan /m3 in the complete cost sailor, the agricultural water fixed quantity tends to be reasonable. Considered that sailor promotion bearing capacity carries on the analysis, obtains the agricultural sailor reasonable collection scope approximately between 0.27 Yuan /m3-0.34 Yuan /m3.
