摘  要：
综合考虑地膜覆盖技术对农作物产量的正面效应和地膜残留对农作物产量的负面影响,构建了地膜覆盖技术对农作物产量影响的评价模型,并以湖北省为例进行了评价。结果表明,湖北省在使用地膜覆盖技术36a后,残膜所造成的农作物减产率将大于由地膜覆盖技术引起的农作物增产率,残膜对农作物产量的负效应再持续16a则可以抵消由于地膜覆盖增温保墒使农作物增加的全部产量。由此可见,从长远来看,在现有残膜回收技术条件下使用地膜覆盖技术是不经济的。

摘  要：
Considering the positive effects of plastic-film mulch and negative impacts of plastic film residue synthetically,the evaluation model of effect of plastic-film mulch on crop yield was constructed.Using the experimental data and investigation data of Hubei province,the effect of plastic-film mulch on crop yield was evaluated based on the model.The results show that the yield reduction rate caused by plastic film residue will be greater than the yield increasing rate caused by plastic-film mulch after 36 years using plastic-film mulch techniques.If the negative effects of plastic film residue on crop yield lasted another 16 years,the reduction of yield will be equal to the total increasing yield cased by plastic-film mulch techniques.That is to say,the use of plastic-film mulch is uneconomic under existing plastic film collecting technology in the long run.
