Driving Factors and Countermeasures of Grassland Desertification in Qilian Mountain Area

As a example for Qilian mountain areaof Sunan County,the paper analyzes mountain-grassland desertification ofthe present state and the variation tendency in Qilian mountain area and combined with its history from both nature and human factors to probe into reasons of grassland desertification.The nature factors are bases of grassland desertification,and human factors are its dominance. So the paper puts forward a series of control of grassland desertification and reconstructioncountermeasures on ecological environment mainly in human factors.These measures focus on increasing capitalinput and introducing and popularizing some new techniques, adopting effective steps to reduce grassland pressure,and realizing reasonable use of water to improve grassland quantityand quality.Implementingthese measures can inhibit more development of grassland desertification,and result in the healthy development of the regional environment.
