In China, college sports resources are relatively abundant in all social elements, plays a major role in promoting the development of social sports, H city, as one of the three education base, the development of college physical education environment has reference significance for National Universities. However, due to the mathematical algorithm in the environmental assessment are often too complex, collecting of environmental data has high difficulty, the previous research mostly about policy macro discussion. This article is based on the full collection of data and former research, using BP neural network analysis method to data mining. And，we use computer to reduce the complexity of the algorithm, make the algorithm to evaluate becomes feasible. It can get H city colleges sports development environment evaluation results, hoping to be able to promote the further development of the sports industry in our country.
