摘要： An indicator screening model is proposed for urban green development evaluation. The main specials and contributions are as follows. Firstly, it uses the approximation classified quality in rough set to determine the importance. Secondly, for purpose of eliminating the multi-collinearity among indicators it uses cluster analysis method to divide the indicators into some different subclasses, and only retains these with the smallest approximation classified quality in each subclass. Thirdly, in order to avoid subjectivity for the determined final number of subclasses it uses the K-W test to examine the rationality of the indicator cluster result. Finally, it establishes an evaluation indicator system including 18 indicators for the urban green development evaluation of Dalian city. ?, 2015 ICIC Express Letters Office.All Rights Reserved.
