Evaluation on Effect of Foreign Trade on China's Ecological Environment by RS and SVM Combined Model

This paper applies rough sets(RS) and support vector machine (SVM) model to the evaluation field to solve the problem that foreign trade causes the environmental issues. First of all, reduce the foreign trade ecological environment indicator system using rough set, get the reduced minimum indicator set based on minimal loss of information, determine the weight of each indicator, and then use the evaluation method of support vector machines and Matlab to realize the evaluation result on effect of foreign trade on China's ecological environment. Research shows that China's foreign trade environment effects is negative.
