Benthic Macroinvertebrate Community Structure and Water Quality Bioassessment in Lijiang River,Guilin,China
摘要
Abstract
Macroinvertebrate assemblages were collected using a D-frame net at 78 sites in Lijiang river, Guilin,Guangxi province,in March 2008,November 2008 and March 2011,respectively,and physico-chemical variables were measured at the same time. A total of 169 macroinvertebrate taxa were collected in March 2008,and the other 120 and 215 macroinvertebrate taxa at other time respectively. Insecta was dominant both in species richness and abundance. Pearson correlation analysis showed that the Shannon-Wiener index was negatively significant correlated with total nitrogen (r=- 0. 390,p = 0. 003) and total phosphorus (r=-0. 510,p = 0. 000),and the biotic index was positively correlated with total nitrogen (r=0. 333,p = 0. 012) and total phosphorus (r=0. 384,p = 0. 003). There are at least 60% of monitored streams in the quality of clean by the Shannon-wiener diversity index and BI,and less than 10% of monitored streams in the condition of heavily polluted. The results showed that Shannon-Wiener diversity index and BI had the potential use in assessing Lijiang river biological condition with macroinvertebrates.关键词
