摘　　要：全生物降解塑料由于其环境友好性,已成为传统塑料的重要代替材料,目前在一次性用品、包装、纺织、农业地膜等领域获得应用。然而,全生物降解塑料完成其使用寿命进入环境后,在不同环境因素作用下,其降解行为和机制目前尚未全部明晰。分析了近年来影响全生物降解塑料环境因素的研究进展,总结了全生物降解塑料的种类、辐射、氧气(O2)、温度湿度、微生物、动植物等环境因素对全生物降解塑料的降解行为的影响规律,并对全生物降解塑料废弃物资源化利用相关领域的研究及发展进行了展望。Biodegradable plastics(BPs)have become the alternative materials to replace the traditional plastics due to their environmental friendliness.They have gained applications in the areas of disposables,packaging,textiles,agricultural mulch,etc.However,the mechanism and laws of affection of various environmental factors on the degradation behaviors of decommissioned biodegradable plastics wasted in the environments are still unclear.In this paper,the recent research progress on the environmental factors affecting on the degradation behaviors of biodegradable plastics were analyzed,and the degradation mechanisms and laws of biodegradable plastics types,radiation,O2,temperature and humidity,microorganisms,plants and animals in the environment on the biodegradable plastics were summarized,Moreover,an outlook on the research and development in the fields related to the resource utilization of biodegradable plastic waste was provided.
