Land Desertification and Sustainable Development in Heihe River Basin, Northwestern China

The Heihe River Basin,located in the northwestern China,is an area of typical arid to semiarid features.During the last century,especially the last half century,mankind’s production activities have caused lots of environmental degradation problems in this basin.Desertification has become a great threat to the whole basin for the future and it requires great effort and resources to ameliorate.Based on investigation and previous studies,the authors analyzed the status of land desertification and the relationship between desertification and sustainable development in the Heihe River Basin.In the end,some possible solutions that may help to ameliorate the situation are suggested.
