基于环境保护发展视角下可降解性地膜综述研究
A Review of Biodegradable Plastic Film from the Perspective of Environmental Protection and Development

西藏雅鲁藏布江沿河农业种植地域是西藏重要的粮食生产区域，农牧民覆盖地膜种植农作物是保障农业粮食安全生产的有效方法和重要途径之一。经过多年的种植业发展，农用地膜的普及覆盖越来越受到农牧民的欢迎，基于环境保护的发展视角，常规农用地膜及其塑性残留物对土地及周边环境造成了严重的污染且越来越严重。国家提倡高原农牧业高质量发展，提出生态环境保护的发展理念，各种新型农业种植方式、农业投入品以及农业绿色发展模式应运而生。可降解地膜作为农业投入品之一，是研究解决农业面源污染、土壤营养失衡、促进绿色生态环境保护的有效方法和途径之一。本文通过详细调查和统计目前高原农业生产领域应用的可降解地膜的种类、特征、应用优缺点和使用效果，分析可降解地膜对于种植业绿色发展产生的影响，提出未来可降解地膜的发展方向。今后对于提升和保障西藏雅鲁藏布江沿河流域种植业高质量发展、安全生产、环境保护治理，促进和发展西藏经济、社会、人口、资源、环境以及粮食安全可持续发展具有重要的意义，仅供学术界参考。
The agricultural planting area along the Yarlung Zangbo River in Xizang is an important food production area in Xizang. Plastic film covered by farmers and herdsmen to plant crops is one of the effective methods and important ways to ensure the safe production of agricultural food. After years of planting development, the popularization of agricultural film coverage has become increasingly popular among farmers and herdsmen. Based on the development perspective of environmental protection, conventional agricultural film and its plastic residues have caused serious pollution to the land and the surrounding environment and become more and more serious. The state advocates high-quality development of agriculture and animal husbandry in the plateau, proposes the development concept of ecological environment protection, and various new agricultural planting methods, agricultural inputs and agricultural green development models have emerged. As one of agricultural inputs, biodegradable plastic film is one of the effective methods and approaches to study and solve agricultural source pollution and soil nutrient imbalance and promote green ecological environment protection. This article conducts a detailed investigation and statistics on the types, characteristics, application advantages and disadvantages, and use effects of biodegradable plastic films currently used in the field of high-altitude agricultural production. It analyzes the impact of biodegradable plastic films on the green development of the planting industry and proposes future directions for the development of biodegradable plastic films. In the future, it will be of great significance to improve and ensure the high-quality development of the planting industry, safe production, environmental protection and governance along the Yarlung Zangbo River in Xizang and promote and develop the sustainable development of Xizang’s economy, society, population, resources, environment and food security.
