本文在分析我国农用地膜覆盖面积与使用量逐年加大、使用区域由西部向东部急速扩张特征的基础上，探讨了残膜污染态势、残膜造成的土壤理化性质恶化程度以及生态环境恶化风险。从普通聚乙烯地膜降解难且产品质量标准不达标、地膜回收困难再利用效率低、可降解地膜工艺不成熟、尚无可替代产品以及地膜污染缺乏监管机制四个方面梳理了地膜污染的成因。在此基础上，提出了加强地膜标准化生产控制，严格执行地膜厚度≥0.01 mm 的国家标准；优化地膜田间科学合理使用，开展作物适时揭膜技术推广；改进提高残膜回收机效能，努力实现地膜零残留；加大可降解地膜研发力度，推广可降解地膜田间应用的农用地膜防治战略，为我国农用地膜合理利用提供参考。

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.
