Abstract

Because of brittle environment, desert-loess boundary belt is sensitive about climate changes and human activities. In the past ten years, the trend of sandy desertification in Yulin area has reversed due to the emphasis on the prevention and control of sandy desertification. However, the potential treat to this area can not be neglected. Conditions of water-erosion desertification are rather serious there. This problem should be tackled actively and effectively. Desertification is a natural course. It is because of the brittle ecological environment together with the irrational way of using the water and land resources that caused the condition of desertification tow orsen. Therefore,the relationship between human beings, resources and environment should be reasonably handled,so as to achieve a sustainable development in society and economy.
