摘　　要：介绍了国内可降解农用地膜材料的研究开发现状,指出了目前可降解地膜发展中存在的问题,并对可完全降解地膜的发展趋势进行了讨论。结论认为:由于技术、成本、认识等方面的限制,可降解地膜的仍处于试验和推广应用阶段;但是可降解地膜无疑是解决"白色污染"较有效的途径,具有广阔的市场前景。The development status of degradable mulching film is introduced. The development problems of degradable mulching film are pointed out, and its development trends are analyzed. The conclusion shows that degradable mulching film is still at experimental and extending stage due to the limitations of technology, ligh cost and general recognizations. In any case,the use of degradable mulching film is a good way to solve the problem of 'white pollution' and promises a wide market foreground.
