从热力学出发，分析了工业生产活动污染环境的熵本质，提出了度量工业生产活动的环境影响非平衡态熵流模型，并分别对三种不同生产模式的熵增值进行计算，得到三种不同生产模式的环境影响趋势，为可持续发展的生产模式的选择提供依据。

The impropriety industrial production mode is one of the main causes of environmental pollution. From thermodynamics, this paper analyses the entropy essential of the pollution of industrial production. On the basis of this, a dynamic equilibrium entropy flow model is set up to measure the infection of industrial production to the environment. Taking three production modes for example, the entropy increase quantity is calculated by using the model and the environmental effect trends can be educed. It can provide decision-making basis for choice of sustainable production mode.
