以多样性指数定量表示生物群落组成结构的数学模式很多,许多人认为以Shannon—Werver多样性指数H’较为理,想已应用于海洋各种生态系生物组成结构的分析。文献早就提出了用多样性指数评价水域污染,但至今未引起国内应有的重视,究其原因,可能认为影响H’值的因子太多,除了污染因子以外,还有环境因子和生物本身的因子,且在目前又难以将这些非污染因子与污染因子的影响分开。因此,
Many people think that the Shannon-Werver diversity index H ’is more reasonable and has been applied to the analysis of the compositional structure of organisms in various marine ecosystems by using the diversity index to quantify the compositional structure of biological communities. Literature has long put forward to use diversity index to evaluate water pollution, but so far it has not attracted much attention in China. The reason may be that there are too many factors that affect H ’value, besides the pollution factor, the environmental factors and the biological itself Of the factors, and at present it is difficult to separate these non-polluting factors and polluting factors. therefore,
