Now,eco-environment quality evaluation is growing up.As a trial,this article applies grey clustering method to this work.It introduces the principle and general process of grey clustering,displays the general steps of the evaluation process,and chiefly analyzes the choice of indexes and the evaluation model.As a study area,the comprehensive evaluation model for ZunYi county of Guizhou Province of China is built with this method.Resources and environment,population and economic data,and hazard data are adopted.The evaluation results indicate that the ecological environment quality of eastern part of the county is much better than the west part,which is identical with the fact.This proves that the model is scientific and impersonal.The method can also be used for eco-environment quality evaluation of other regions.
