塘-湿地生态复合处理系统的硅藻生物指数评价
首发时间:2008-09-24
摘要:对塘-湿地生态复合处理系统的硅藻群落组成进行分析,并利用Shannon-Weaver多样性指数(H )、Simpson多样性指数(D)、Lloyd-Ghelardi均匀性指数(E)、Margalaef丰富度指数(R)四种生物指数和模糊评价方法对其水质评价,结果表明:厌氧塘和兼性塘为α-中污带,好氧塘为β-中污带,生态湿地为轻污带,生物监测和理化监测结果基本一致。

The diatom biology index appraisal in pond-wetland combined eco-system
Abstract:Composes to the pond-wetland combined eco-system in diatom community carries on the analysis, and using the Shannon-Weaver diversity index( ), the Simpson diversity indices(D), the Lloyd-Ghelardi evenness index(E), the Margalaef abundance index (R)four of living thing indices and the fuzzy assessment method to its water quality appraisal, finally indicated: Tires of the oxygen pond and the optional pond for alpha - the dirt belt, good oxygen pond for beta - dirt belt, ecology wetland for light dirt belt, biological monitor and physics and chemistry monitor result basic consistent.
Keywords: Diatom Biological index Fuzzy membership function
