The Assessment Of Sandy Ground Water Reource Squantity Inyanchi Countryin In Ningxia

The water resource is the indispensable natural resources of human production and life, is the environmental resources that the living beings depended on for existence too, As aggravation of the crisis of water resource and water environmental quality worsen constantly, water resource shortage has already developed into one of the resources environmental question that the world is paid close attention to extremely. The area of Ningxia belongs to semi-arid-region extremely shortage of water resource, there is a lot of loophole in using management.This paper is as the research object with the water resource of sand ground of Yanchi county of semi-arid-region in Ningxia. To this area precipitation materials for many years, evaporate materials, surface flow materials, hydrometeorological materials, hydrogeological materials carry on exhaustive analysis, Have analysed the state of water resource of the sand district, proceed from the heat of the earth's surface is balanced, water yield balanced basic theories, Combine the amount of regional water resource set up of the materials, such as scene, hydrology, soil of the sand district, etc. and estimate models, Have calculated the surface water, groundwater of this area, has carried on models to examine according to the real data, And has predicted to the state of water resource under different climate change scenes of future that analyse. Have put forward the scheme that the water resource in this area utilized rationally, use the non-linear motive force model to predictthe precipitation, Utilize the materials of actual observation, the natural supply amount of calculating out groundwater of sand ground of balanced principle of the amount of water used at the same time , And can exploiting amount predict to groundwater, district of sand,. In addition, the water resource is appraised on the issue that water yield science disposes, besides considering that the sand district produces the domestic water this time, Consider sand district base on the premise that guarantee social economic development, must meet ecological environment demand ink request of sustainable development too.On the basis of above-mentioned appraisal on the water resource, plan to utilize the suggestion after putting forward the water resource in the future in the sand district finally, And uses and puts forward the rational suggestion to the water resource management of half a arid area in Ningxia.
