计算环境质量综合指数的K─级混合加权模型

MIXING WEIGHTED K-MODEL FOR CALCULATINGCOMPREHENSIVE INDEX OF ENVIRONMENTAL QUALITY

用综合指数进行环境质量评价，能反映环境质量问题。但是在综合指数的计算中，如何确定权系数的问题仍未完全得到解决。混合加权模式解决了权系数的确定及区分环境污染与否的问题，不过在单项分指教较多（超过９个）时，其模式仍有不完善之处，本文将对混合加权模式加以改进，提出一个比较完善的计算环境质量综合指数的模式─－Ｋ─级混合加权模型。

Assessing environmental quality wilh comprehensive index is a good way for indicating totalenvironmental quality.How lo determine the weighted number spstem obJectively whentalculating the comprehensive index is a problem that has not been solved completely.In themixing weighted inodel the determination of the weighted number system has been solved andsuch a model can also distinguish clearly between pollution and non-pollution. But when thenumber of single factors of environment is over 9, the mixing wcighted model is not completeyet. In this paper we improve the mixing weighted model and give a complete model to calcu-late the comprehesive index ol envirtinmental quality.
