摘　　要：近年来,我国缓释肥料产量和消费量跃居世界前列,包膜材料的安全风险问题引起广泛关注。介绍了包膜材料的使用现状,分析了各类包膜材料安全性、人工合成高分子材料降解性以及膜材残留积累对土壤生态环境影响的安全风险;系统研究了包膜材料的生物分解能力、生态毒性等环境影响评价方法及标准指标;提出了包膜材料使用的安全风险划分等级,以期为科学评价包膜材料和合理使用包膜缓释肥料提供技术手段,降低包膜材料对农产品和生态环境的影响风险。It is widely concerned in terms of the safety risk of using coating materials of slow-release fertilizers because China has leapt to the world’s forefront for the output and consumption in recent years.By introducing the current application of coating materials and analyzing their safety risks including the safety of materials,the degradability of synthetic polymers and the impact of coating materials residue and accumulation on the soil ecological environment,the paper makes a systematic study of the environmental impact evaluation methods and standard indexes of the biodegradability and the eco-toxicity for coated materials.And the grade classification of safety risk for coating materials is proposed,in order to provide technical methods for the scientific evaluation of coating materials and rational use of slow-release fertilizers,and to reduce the impact and risk of using coating materials on food and eco-environment.
