漳泽水库藻类Shannon-Weaver物种多样性指数H’趋势分析

Trend Analysis of Shannon-Weaver Species Diversity Index H’

通过对漳泽水库2010到2013年藻类监测资料Shannon-Weaver物种多样性指数H’分析,水库不同区域评价结果具有一定的相关性,差异不大,年际变化不明显.按照Shannon-Weaver物种多样性指数污染程度表,水库的污染水平都处在清洁或者中污染的水平,中污染主要集中在气温较高的夏季.藻类的生物多样性处在中等偏好水平,较为丰富,这与水库的营养物质较多,处于轻度富营养化的状况相对应.

Based on the analysis of Shannon-Weaver species diversity index H7 of algae monitoring data in Zhangze Reservoir from 2010 to 2013,the evaluation results of each sampling point in the reservoir had certain correlation,but the difference was not significant.According to Shannon-Weaver species diversity index pollution degree table,the pollution level of reservoirs was in clean or moderate pollution level,and the moderate pollution mainly concentrates in the summer when the temperature was high.The biodiversity of algae was in the middle preference level and relatively rich,which corresponds to the condition of mild eutrophication with more nutrients in reservoirs.
