| 摘 要： | 在对湖泊生态系统健康评价研究的基础上，提出用营养状态-综合指数法（TSI-CI）对西湖进行生态系统健康评价．首先选用Chl．a、SD、TP和TN四个指标用相关加权指数法进行营养状态评价，再选择物化和生物指标无量纲化处理后计算综合指数进行综合评价．结果表明：西湖生态系统健康状况与营养状态水平的变化趋势是一致的，1—3月健康状况相对较好，7-9月相对较差．该结果客观反映了西湖的实际情况，为西湖水质管理提供科学依据。

| Abstract: | Ecosystem health was a newly proposed concept in the world with the environment becoming serious issue and on ecosystem health assessment. A method, trophic state-comprehensive index based on researches on the lake ecosystem health had been proposed to evaluate the ecosystem health of Lake West. Firstly, four indices including Chl.a, SD, TP and TN were choosed to calculate the TSI. Secondly, undimensionalizated indices such as physical, chemistry and biology was used to calculate comprehensive index to esti... |
