水体增温对浮游植物群落结构及其生态学特性影响的研究

本文对受河南平顶山姚孟热电厂温排水影响的白龟山水库的浮游植物群落的情况进行了野外调查,并在室内对浮游植物的群落结构及其生态学特征进行了模拟增温试验。试验结果表明:水体增温对水库浮游植物的种群组成、优势种的优势度、藻类密度和生物量均有影响。影响的程度与环境固有的水温及增温强度有关。室内增温模拟试验还表明:连续的增温对藻类的光合色素含量和光合作用强度均有影响。

The Study on Effects of Increased Temperature of Water Bodies on the Community Structure and Ecological Character of Plytoplankton

A field investigation and increased temperature test of water simulated indoor were conducted on phytoplankton in Beigushan Reservior, Henan Province ( as affected by the cooling water discharge from Yaomong Power Plant ). The results of investigation and indoor simulated test showed there were effects of increased water bodies temperature on the structure, dominant, density and biomass of phytoplankton community. The level of effects was related to the natural water temperature and the intensity of the increment. The effects of increased temperature of water bodies on the quantity of photosynthetic pigment and photosynthesis were also found.
