Abstract: Study on human effect is an important field in desertification research, and its also an important part of desert scientific system. Human activities have active and passive effect on land desertification. Unreasonable human activity accelerates desertification process, but scientific reclamation approach can reverse the process. By now, important progress have been got in research on the effect of human factors to desertification, mechanism of human activity to desertification, the relationship between desertification and human activity in history, quantitative analysis on human effect to desertification, driving factors of human activities. Also, major achievements have been got in technology, mode and approach of desertification control in our country. There are still some problems existed in this research field, such as whether human factor or nature factor plays a more important role in desertification process, the clear mechanism of human activity playing role on desertification need to be solved, the further discussion that population is direct or indirect reason of desertification are going to be conducted. This article tries to give a brief summary of human effect research on desertification, also give an outlook of human effect research on desertification in the future. The human effect should be the main subject of desertification research in the future; this research scope should be extended.
