摘　　要：本文研究了温度、pH值、光照三种环境因子对伊乐藻光合作用的影响,实验得出伊乐藻顶枝光合作用的产氧量与温度、光照呈曲线相关,与pH值呈线性负相关。华南河网地区的环境因子基本处于伊乐藻适宜的生长范围之内,选择其作为该地区受损水域生态修复的沉水植物是比较合适的。In this paper, the effects of environmental factors such as temperature, pH and illumination on the photosynthesis of Elodea nuttallii were studied. By experiment it was found that the production of oxygen of Elodea nuttallii＇s telome through photosynthesis had curved correlation with the temperature and illumination, while negative linear correlation with pH. The environmental factors of plain river network region in Southern China are fit for the growth of Elodea nuttallii, selecting it as a species of submerged plant to restore the regional ecology is very appropriate.
