摘要

Water Shortage and desertification is the serioius environmental problems in NW China. Desertification usually leads to poverty. Poverty means people have no surplus resources which then result in the mining of the environment. The water in the Shiyang River, which is the main river feeding Minqin basin, is over-used for irrigation and little or no surface water now reaches the Minqin Basin itself. As of 1995, total water storage of 23 reservoirs was about 450x10~6m~3. As a result farms in the Minqin Basin are now dependent on the pumping of groundwater for both irrigation and drinking purposes. This has caused a gradual reduction in the level of groundwater and a huge lake, approximately 500 square kilometres in extent in the centre of the basin has now disappeared completely. Freshwater can now only be obtained by pumping from wells 300 metres deep and the well number arrived to 10000. This bas been resulting in vicious circles of ecological degredation and poverty. A project is conducted in oasis communities in Minqin County where desertification and ecological environment are most serious in the Hexi Corridor of Gansu Province so as to reach purposes of integrating desertification control with poverty reduction based on community development approaches. The impact on Water saving and desertification control is visible. It is necessary to step up a higher stage of water management and increase the water saving techniques in the whole basin. A water laws is needed to ensue strictly the water users and provide unified development and allocation within the river for socioeconomic development and fragile ecology protection. Meanwhile, it is a possible way to stop the desertification and pauperization to substitute the agriculture for the stock raising.
