Abstract：The intensive facility agriculture is an important part in Chinese agricultural production systems．However，continues cropping and simple rotation，these 2 conventional practices are relying on limited land area with large input of chemical fertilizer and pesticide，and have caused soil degradation and brought obstacles to plant growth，resulting in a reduction of plant production．Thus，how to reduce the soil function degradation，improve soil quality and realize the sustainable development of greenhouse vegetable production becomes an issue demanded be solved．Catch crop is a biological tool to minimize soil degradation．With the continuous studies on soil nutrient cycling by catch crop，people’s understanding about catch crop mechanism and its ecological efficiency has become more and more thoroughly．The paper expounded the research progress made both in China and foreign countries about effects of catch crops on reducing soil function degradation and analyzed the feasibility of using catch crop to reduce soil function degradation in greenhouse vegetable field．
