摘 要
塑料垃圾污染已成为全球性环境问题，其在环境中难以降解且易造成土壤、水体等多方面污染。本研究旨在深入探讨塑料垃圾污染的环境影响并研究生物降解材料以寻求解决之道。通过文献调研与实地采样分析相结合的方法，对不同地区典型环境中的塑料垃圾分布及危害进行调查，同时运用化学成分分析、微生物群落结构测定等手段探究生物降解材料的降解性能。结果表明，塑料垃圾可释放有害物质干扰生态系统平衡，影响动植物生长发育，在海洋环境中还可能被误食进入食物链；而所研制的生物降解材料在特定环境下能够有效降解，其降解产物对环境友好。本研究创新性地提出了一种新型生物降解材料配方，并构建了评估塑料垃圾环境风险和生物降解材料降解效果的综合模型。

Abstract
Plastic waste pollution has become a global environmental problem, which is difficult to degrade in the environment and easy to cause soil, water and other pollution. This study aims to explore the environmental impact of plastic waste pollution and study biodegradable materials to find solutions. Through the combination of literature research and field sampling analysis, the distribution and harm of plastic waste in the typical environment of different regions were investigated, and the degradation performance of biodegradable materials was explored by means of chemical composition analysis and determination of microbial community structure. The results show that plastic waste can release harmful substances to interfere with the balance of ecosystem, affect the growth and development of animals and plants, and may be eaten into the food chain in the Marine environment; and the biodegradable materials developed can be effectively degraded in a specific environment, and their degradation products are friendly to the environment. This study innovatively proposed a novel formulation of biodegradable materials, and constructed a comprehensive model to evaluate the environmental risk of plastic waste and the degradation effect of biodegradable materials.
