The research of interaction between desertification and climate change is an academic hot issue and a difficult problem. Desertification is sensitive to climate change; meantime,it may feed back to climate change through special environmental characteristics. Climate change alters vegetation coverage and other surface features through temperature and precipitation change,and finally,it has profound influences on desertification. While,desertification may has influence on regional climate change through biogeophysical feedbacks,increasing greenhouse gas concentration of CO_2,releasing dust aerosols,altering soil moisture and surface roughness. Many researchers at home and abroad have researched the interaction between desertification and climate change and published many papers,but up to now,the interaction mechanism between them is still not clear. There are some problems need to be solved in future: to separate the natural and anthropogenic factors,data deficiency and continuity and comparability of data,defect of models and the problem of spatial - temporal scale. Considering these problems,some prospects are also put forward in this paper: to enhance experimental observation and others for obtaining long-term data, to improve models and to conduct integrated study on the interaction between sandy desertification and climate change.
