Abstract

Abstract: This paper studies the selection of index system for evaluation of regional ecological security and weighting method,establishes the model of the principal component projection to assess regional ecological security.Through the empirical analysis of seventeen regions in Anhui province,the paper proves that the method is reasonable which can be used as theoretic basis for studies on evaluation of regional ecological security and management of eco-environment.

Key words: regional ecological security, evaluation index, principal component projection, entropy method
