珠海市重要湿地鱼类多样性

2015年10月,调查了珠海湿地水域的鱼类资源。共采集鱼类样品261尾,隶属于7目16科22属23种,其中鲱形目2科3属4种;鲤形目2科6属6种;鲶形目1科1属1种;鲻形目1科1属1种;合鳃鱼目1科1属1种;鲈形目8科9属9种;鲽形目1科1属1种。Margalef物种丰富度指数为1.022~2.635;Simpson指数为0.365~0.765;Shannon-wiener多样性指数为0.722~1.961;Pielou均匀度指数为0.448~0.765。珠海湿地水域的鱼类群落多样性较低,各样点间的鱼类组成差异明显。

Fish Diversity in Major Wetlands of Zhuhai City

In October 2015, a survey of fish resources in wetlands of Zhuhai was conducted. A total of 261 fish samples were collected, belonging to 7 orders, 16 families and 22 genera and 23 species. Margalef species richness index was 1.022 to 2.635;Simpson index was 0.365 to 0.765; Shannon-wiener diversity index was 0.722 to 1.961; Pielou evenness index was 0.448 to 0.765. The fish diversity in the wetlands of Zhuhai was low, and the difference of species composition of fishes among different sampling points was significant. In this paper, according to the ecological characteristics of the survey results, influencing factors were identifed, and a strategy for the protection of fish resources was proposed.
