中文摘要	从沙漠化定义出发,阐述了沙漠化驱动因素研究的发展历程。分析了温度、干旱、风等自然驱动因子和人口与牲畜数量、土地利用方式、技术、政策等人文驱动因子对沙漠化的影响,系统梳理了沙漠化过程中自然和人文驱动因子的定量辨识方法。指出目前评价方法的不足和片面性,应进一步考虑沙漠化过程中的微观变化,加强人文与社会经济学角度的研究,提高数据精度和数据库建设步伐。
英文摘要	This paper attempts to introduce the developmentand various research ideas that account for desertification under the definition of desertification and all the likely factors leading to the consequence of desertification. Starting from the academic stand of view, we have analyzed the impacts of all the likely influential factors responsible for the desertification. In our points of view, such factors in nature can be illustrated as the temperature change, the long-lasting drought, the wind and human intervention into suchfactors, as the population and livestock size, the land use patterns, the agricultural technologies and policies concerned. Desertification of itself is the degradation of the land quality in arid and dry sub-humid areas due to the above mentioned factors. Of such factors, the climate change and human activities canbe regarded as the two chief driving forces responsible for the desertification process. And, it is the discrimination between the climate and human-induced desertification that has become a serious challenge for the management of desertified areas, which idea has begun to attract closer and closer public attention. Based on the above penetrating analysis, we have made a systematic review of the progress of the principal functions and the relative roles of the driving factors accounting for the desertification process. Therefore, this paper has described the well-used principal component analysis method and the residual trends (RESTREND) methods, including the principles, calculation process, approach to applications, research findings, the advantages and disadvantages due to their application, as well as the application of some other commonly used methods. Based onthe analysis of the advances of the previous research achievements and the study of the currently existing problems in the field, we have put forward a new idea of ours that we should further consider the microscopic changes in the desertification process, strengthen the exploration of the influential factors from the perspectives of humanity and social economic development, in addition to improving data accuracy and database construction. It is of great significance to prevent from and control the desertification more effectively, so as to keep the sustainable development and the ecological safety of the areas concerned.
