摘　　要：ＧＯＳＳＹＭ模型是迄今为止世界上最著名的棉花动态解释性模型，将其应用于新疆的大面积地膜植棉生产，需要对模型做适当的修改。本研究通过试验重点论述地膜覆盖对地温的增加效应和规律以及对气温的补偿作用。并通过试验证明，地膜与露地地温符合幂函数关系（ｒ＞０．９７），可用于修改ＧＯＳＳＹＭ模型。GOSSYM simulation model has been wildly used in the world to interpret the dynamic growth of cotton. The model needs to be modified if applied it to Xinjiang large area cotton production which has the feature of plastic film covering. Through the plot test this paper discussed mainly the effect of plastic film cover on the increase of soil temperature ,its patterns and its compensation for the air temperature. The test indicates that the mulched and the bare soil temperature conform to the power function (r>0.97).This could be used to modify the GOSSYM simulation model.
