摘  要：
调查锦江河国家级水产种质资源保护区浮游植物群落及研究其时空动态,对水体进行评价,为在保护区开展相关资源保护工作积累本底资料和保护区涉水工程环境评价提供素材。在核心区和试验区各设置5个共10个采样点,2015年1月(冬季)、4月(春季)、7月(夏季)和10月(秋季)进行采样。共鉴定浮游植物6门17目1亚目32科45属101种,其中硅藻门最多、42种,占41.58%;绿藻门次之、32种,占31.68%;保护区为硅藻-绿藻型河流;浮游植物密度夏季最大,2.59×106个/L;冬季最低,仅0.18×106个/L。Margalef指数、Shannon-Wiener指数、Pielou指数季节变化趋势一致,夏季都达到最大,分别为2.99、2.30和0.85;冬季最小,依次为1.89、1.73和0.55。利用浮游植物密度评价保护区水体为贫营养水体,多样性指数评价水体介于β-中污染带到寡污染带,综合分析锦江河国家级水产种质资源保护区整体上说为β-中污染或贫营养水平。

摘  要：
Jinjiang River National Aquatic Germplasm Reserve is located in Tongren City,Guizhou Province,and the river maintains a healthy aquatic ecosystem. In this study,we explored the structure and spatial-temporal dynamics of the phytoplankton community in the section comprising the national aquatic germplasm reserve. The water quality of the reserve was then evaluated based on the biodiversity indices and phytoplankton density. The results will add to the accumulating database used to support resource conservation and environmental assessment by the wading engineers at the reserve. In January( winter),April( spring),July( summer) and October( autumn) of2015,phytoplankton surveys were carried out in the core zone and the multiple-use experimental zone of the national reserve,with 5 sampling sites in each area. A total of 101 phytoplankton species,belonging to 45 genera,32 families,18 orders( 1 suborder) and 6 phyla,were identified. Bacillariophyta dominated( 42 species),accounting for 41. 58% of the total species,followed by Chlorophyta( 32 species),accounting for 31. 68% of the total species. The number of phytoplankton species in the core zone was much lower than in the experimental zone. Phytoplankton density reached a maximum of 2. 59 × 10~6 cells/L in summer and a minimum of 0. 18 × 10~6 cells/L in winter. Margalef richness,Shannon-Wiener diversity and Pielou evenness indices reflected the seasonal variation,with values,respectively,of 2. 99,2. 30 and 0. 85 in summer and 1. 89,1. 73 and 0. 55 in winter. Phytoplankton density and biomass were higher in the experimental zone as were the Shannon-Wiener diversity and Margalef richness indices: 2. 73 and 2. 28 in the experimental zone compared to 2. 40 and 1. 74 in the core zone. The Pielou evenness index was higher in the core zone. In general,the water quality in the Jinjiang Aquatic Germplasm Reserve was β-mesosaprobic-oligosaprobic,based on the phytoplankton density and biodiversity indices.
