摘要
恢复或重建沉水植物群落被认为是富营养化浅水湖泊生态修复中的一种行之有效的措施,从众多生态修复研究和工程项目中可以发现沉水植物恢复的进程受到了多种环境因子的综合限制。综述了水下光照条件、水体营养盐和底质3种关键环境因子对不同沉水植物生长的影响,提出了今后沉水植物恢复和构建研究应加强的3个方面:构建水质参数与光衰减的数学模型,系统研究光照强度对沉水植物群落结构的影响;多种营养盐交互作用下对沉水植物生长和种群扩张影响的阈值研究;底泥特性对沉水植物生长和繁殖体萌发影响的基质研究。
The restoration or reconstruction of submerged macrophyte communities is considered to be an effective measure in the ecological restoration of eutrophic shallow lakes.It has been found in numerous ecological restoration research and engineering projects that the process of submerged macrophyte restoration is comprehensively restricted by a variety of environmental factors.This review summarizes the effects of three key environmental factors of underwater light conditions,water body nutrients and substrate characteristics on the growth of different submerged macrophytes,and proposes three aspects that should be strengthened in future research on the restoration and construction of submerged plants:construction of water quality parameters and light attenuation mathematical model and systematic study of the influence of light intensity on submerged macrophyte community structures;study on the threshold of the influence of various nutrient salts on the growth and population expansion of submerged macrophyte;substrate research on the effects of sediment characteristics on submerged macrophytegrowth and propagatorgermination.
