Coverage and use of agricultural plastic films in China has been increasing year by year, and its use area expands rapidly from west to east. Based on these characteristics, this paper discussed the pollution condition of residual plastic films, the deterioration of soil physicochemical properties caused by residual plastic films, and the risks of ecological environment deterioration. And then four causes of plastic film pollution were summarized. Common PE plastic films are difficult to degrade and are always substandard; the plastic films are difficult to recycle and have a low reuse efficiency; the technology of degradable plastic films is immature; and there is a lack of substitute products and supervision mechanism. On these bases, some control strategies for agricultural plastic film pollution were put forward to provide references for the rational utilization of agricultural plastic films in China. For example, standardized production of the plastic films should be promoted and the national standard of plastic film thickness≥0.01 mm should be strictly enforced; the scientific and rational use of plastic films in the field should be emphasized and the timely film uncovering technology should be promoted; the efficiency of residual film recovery machines should be improved, striving to realize zero residual of plastic films; greater efforts should be devoted to the research and development of degradable plastic films and the field application of degradable plastic films should be popularized.
