水电站改造工程区域生态特征与生物资源保护研究——以天台县里石门水电站为例

Study on Eco-features and Bio-resources Protection after Reconstruction of Hydropower Station——A case of Lishimen Hydropower Station in Tiantai County

为加强天台县里石门水电站生态机组改造工程建设后生态保护,对该区域陆生生态及水生生态进行调研。采用路线法、样方法开展调查,并结合当地相关资料分析该区域陆生和水生生态资源现状,对陆生脊椎动物物种多样性及水生生态环境进行总体评价。结果显示,调查区域内陆生植物和动物Shannon-wiener指数分别为1.68和1.29;浮游植物Shannon-wiener指数为0.93~1.22;浮游动物Margalef丰富度指数为5.37~6.34。水电站附近主要陆生生物种类单一,群落稳定性需要提升;水生生态物种丰富,群落结构稳定,水生态环境良好。研究成果可为天台县里石门水电站区域生态修复与生态环境建设提供参考。

In order to strengthen the ecological resources protection after the construction of the ecological unit reconstruction project of Lishimen Hydropower Station in Tiantai County,this paper studied the terrestrial ecology and aquatic ecology of the area.An overall evaluation of the diversity of terrestrial vertebrate species and the aquatic ecological environment was conducted with a combined method of line transect method,quadrat method and investigation on local current situation of terrestrial ecological resources and aquatic ecological resources.The results showed that the Shannon-wiener index of terrestrial plants and animals in the investigation area were 1.68 and 1.29,respectively.Thephytoplanktonofthe index was 0.93~1.22.TheMargalef richness index of zooplankton is 5.37~6.34.Through the analysis of the investigation results,it was considered that the main terrestrial organisms near the hydropower station are single,and the community stability needs to be improved;the ecological species of aquatic eco-environment is rich with stable community structure.These results provide references for the regional ecological restoration and eco-environment construction of Lishimen Hydropower Station in Tiantai County.
