Abstract: The issue of applying Support Vector Machines（SVM） to evaluate comprehensive environmental quality is explored，and an environmental quality evaluation model is proposed based on SVM.A sample of environmental quality from certain area is adopted and tested.The result shows that the model and algorithm proposed possess convenience，objectivity and high practicability，moreover，there need not any complicated parameter equation for its features of knowledge learning.
