摘要/Abstract

摘要： 我国地膜使用量已占农业塑料薄膜使用量的半数以上,其大规模使用在带来巨大经济价值的同时也造成了“白色污染”,残膜难回收、难降解,直接影响土壤的再生能力。本文综述了我国地膜使用现状及其降解方面的研究进展,分别对地膜降解的生物与非生物途径和机理进行了概括,重点分析了非生物降解途径中光催化、金属离子掺杂等对聚烯烃降解的协同效应,以及生物降解途径中不同来源的菌和酶对聚烯烃降解效率的影响,并展望未来发展出更为高效的地膜降解方式,为后续地膜降解及环境中微塑料的降解研究提供参考。

Abstract: Mulch-filmaccounted for more than half of plastic film used in Chinese agriculture. The wide utilization of mulch-film brings great economic value but also causes “white pollution”. The residual film is difficult to be recycled and degraded, which directly affects soil regeneration. We introduced the current status of the plastic film usage in China and reviwed the research progress in its degradation. The biological and non-biological pathways and mechanisms of mulch-film degradation were summarized, with particular focus on the polyolefin degradation with synergistic effect of photocatalysis, metal ion doping as well as the impacts of different sources of bacteria and enzymes on the degradation efficiency of polyolefins. The more efficient degradation methods of plastic film are prospected. This review would provide reference for the further studies of plastic film degradation and microplastic degradation.

Key words: agricultural film, polyethylene, biological degradation, non-biological degradation
