摘　　要：西藏自治区设施蔬菜种植面积达5 300多hm^(2),全区设施蔬菜地膜年用量达80万kg以上。因此,“白色污染”问题已日渐突出。通过对可降解地膜在土壤增温保墒、对作物生长发育的影响、病虫草害的防治以及成本节约等方面的作用进行阐述,以期为西藏自治区设施蔬菜生产及可降解地膜的使用提供理论依据。The planted area of protected vegetable in Tibet is more than 5300 hm^(2),and the mulch of protected vegetable in the whole region were more than 800000 kg in annual consumption.Thus,the"white pollution"problem has becoming increasingly prominent.In this paper,authors expounded the effects of degradable plastic film on soil warming and preservation of soil moisture,crop growth and development,disease,insect and grass damage prevention and cost saving,in order to provide theoretical basis for protected vegetable production and the application of degradable plastic film in Tibet.
