摘    要:目的]探讨环境因子对沙湖叶绿素a含量的影响。方法]应用灰关联方法对2007年11月~2008年9月的沙湖水样进行分析,研究了叶绿素a含量与水温、pH值、透明度、总氮、总磷、高锰酸钾指数等环境因子之间的关系。结果]影响沙湖叶绿素a含量的主要水环境因子依次为水温、高锰酸盐指数、总氮、pH值、总磷和透明度。结论]为沙湖的富营养化治理与合理开发利用提供了理论依据。

关 键 词:沙湖  叶绿素a  环境因子  灰关联分析

Abstract:Objective] The aim was to explore effects of environmental factors on the content of chlorophyll-a in ShaHu Lake.Method] Based on the data in Shahu Lake from November in 2007 to September in 2008,the relationship between chlorophyll-a and environmental factors like water temperature,pH,secchi-depth(SD),total nitrogen,total phosphorus and potassium permanganate index was studied by grey relational analysis method.Result] The main environmental factors affecting the content of chlorophyll-a in ShaHu Lake were in order of water temperature > potassium permanganate index > total nitrogen > pH > total phosphorus >SD.Conclusion] The research provides reference for the control of eutrophication and the reasonable development and utilization of Shahu Lake.
Keywords:Shahu Lake  Chlorophyll-a  Environmental factors  Grey relational analysis
