Environmental Health Assessment on Seagoing Water in Lianyungang City by Entropy Weight Approach-A Case Study of Qiangwei River
摘要
Abstract
This paper assessed the health conditions of the seagoing water in Lianyungang (a case study of Qiangwei River from 2000 to 2007) under the force of rapid urbanization. We used a fuzzy logic approach on entropy weight. The indicator system contained the components of Pressure, State and Response, and the relative membership method used here avoided the uncertainty in estimating the standard of stream health subjectively. The results showed that the relative health status of the Qiangwei River approximately presented downtrend from 2000 to 2007. The most healthy year was 2002, and the least healthy year was 2006; based on the maximum membership degree principle, the maximum membership degree in pressure group was 0.763 9 (2003), in state group was 0.722 4 (2000), and in response group was 1.0000 (2002); the maximum membership degree among all asseessed indicators was in 2002, with a probability of 32.15%.关键词
