水生植物光合作用影响因子研究进展

水生植物在生理上极端依赖于水环境,对水质的变化十分敏感,其生长和分布受多项环境因子的调控.水体中光照、温度及无机碳是影响水生植物光合作用和生长发育的重要环境因子,是开展水生植被研究的基础和热点.光照是水生植物生长的限制性因子,并决定水生植物在水下分布的最大深度,温度主要影响酶的活性进而影响光合作用的暗反应.探讨环境因子对沉水植物的生长发育的影响,可为水环境生态修复提供依据.

Research on Aquatic Plants Photosynthesis Impact Factors

The aquatic plants physiologically closely depend on water environment, which are very sensitive to water quality. Growth and distribution of aquatic plants are regulated by many environmental factors. The light, temperature and in~c carbon are important environmental factors affecting aquatic plants photo- synthesis and growth , which are the foundation and hot topics in aquatic plants research. It is expected that this study can provide scientific data for conservation and sustainable utilization of aquatic ecosystem. Light intensity is recognized as the restrictive factor in the growth of aquatic plants, but also determines the maxi- mum distribution depth underwater. Temperature affects enzyme activity and thus affects the dark reaction of photosynthesis. Therefore, the impact of environmental factors on the growth and development of submerged macrophytes is discussed, providing the evidence for the ecological restoration of water enviroument.
