Research on the Effect of the Future Adjustment of Agricultural Water Pricing Based on the Resource and Environment Water Price on the Quantity of Irrigation Water in Tarim River Basin

According to the models of water fees and environment water prices and relevant data,on the basis of the cost price of water supply,this paper further calculates the future agricultural water price based on water resources fee and environment water prices.Then the paper establishes the model of the effect of agricultural water price on the quantity of irrigation water in Tarim River Basin by using the data of agricultural water prices and the amount of irrigation water use in the basin,and it is used to analyze the effect of the future adjustment of agricultural water prices based on different agricultural saving water prices two elastic parameters of demand of water prices(adjusted and unadjusted);the results indicate that the effect of the adjustment of the future agricultural water on the quantity of irrigational water is very high,but the function of the environmental water price is to carry out the economical compensation of the environmental water use to protect the ecological environment in Tarim River Basin.It is the key approach to improving the effects of the future agricultural water prices by the cooperation of the adjustment of water prices with the high effective water-saving techniques.Especially the research of the effect of saving water of the future agricultural water price is related to the safety of food production and the issue of the farmer's carrying capacity of water prices,is the key contents for the future adjustment of agricultural water prices to discuss,so that the research can be used to guide the future agricultural water pricing.
