摘要

Land desertification is a complex concept which refers to land degradation in the arid region, semi-arid region and sub-humid arid region caused by various factors including climate variability and human activities. It is not only an environmental problem, but also a social and economic one[1]. Land desertification will reduce the biological and economic production potential of the land and even exacerbate the trend of land desertification, leaving serious impact on the economic, social development and national lives of Jilin. In addition, it will result in ecological environment deterioration, microclimate variability, an increase in natural disaster and high frequency of sand blowing. Taking the special geographic area in western Jilin (especially the Tongyu County) as an example, this paper discusses the natural and social factors for the forming of desertification in the microcosmic level, analyzes the current situations and provides reasonable recommendations.
