Abstract:

Taking the Guanling – Zhenfeng Huajiang demonstration area as an example, based on the principal component analysis model, from ecology efficiency, economy level of development and the level of development of society, the appraisal target is screened and the index weight is determinated.Finally, 4 major appraisal targets of affecting the ecology efficiency and the economy level of development, and 3 main appraisal targets ofaffecting the level of society development are determined and construct the comprehensive management efficiency index system.The selected appraisal targets are used to estimate the comprehensive management efficiency of Huajiang model district, using the fuzzy comprehensive evaluation approach,and the result is divided into 5 ranks---worse, bad, good, better and best. The research indicates that the rank of the model district has changed from “bad” to “good”, which shows that the measures has a good trend of development in the short-term ecology efficiency and the level of economy development. Overall, the measures are well integrated.
