| 摘 要： | 以甘肃民勤县土地沙化为研究对象，在实地调查研究的基础上，采用数理统计的方法，对土地沙化与水资源（包括自然降水、地表径流、地下水）、人口、耕地、林地、牲畜、粮食产量等因素之间的相关性进行了定量分析，科学揭示出了民勤土地沙化扩展加剧的驱动机制，为综合整治土地沙化问题提供了科学决策依据。

| Abstract: | Land desertification in Minqin of Gansu Province was taken as research object.Based on the field research,correlativity of land desertification and water resources(including natural precipitation,ground run off,groundwater),population,cultivated land,livestock,and grain output were analyzed quantitatively by using mathematical statistics method.Expansion aggravation of driving mechanism of land desertification in Minqin County is revealed scientifically.Scientific basis for controlling land desertification is provided. |
