光照强度对沉水植物生长和光合作用影响的研究进展

Research Progress in the Effect of Light Intensity on the Growth and Photosynthesis of Submerged Aquatic Vegetation

沉水植物作为重要的初级生产者,在水生生态系统中有着非常重要的作用。沉水植物的生长和分布受到诸多环境因子的影响,其中水下光照强度、水温和矿质元素等是重要的因子。本文综述了光照强度对沉水植物生长和光合作用影响的研究进展,总结了沉水植物对弱光在形态和生理上的适应机制,并对目前研究中存在的问题和今后的研究方向进行了展望,以期为进一步开展沉水植物生理生态学研究及受损生物群落的恢复提供科学参考。

Submerged aquatic vegetation, as an important primary producer, plays an important role in the aquatic ecological system. Growth and distribution of submerged aquatic vegetation are influenced by environmental factors, of which light intensity under water, water temperature and mineral elements are important factors. This paper described the research progress in the effect of light intensity on the growth and photosynthesis of submerged aquatic vegetation, and summarized the morphological and physiological adjustment mechanism of the submerged aquatic vegetation to weak light and put forward the perspectives on problems and future study and it likes to provide the scientific reference for further study on morphology and physiology of submerged aquatic vegetation and rehabilitation of damaged biological community.
