摘要
沉水植物的恢复和重建是水体生态修复的核心目标,然而植物恢复的进程受到多种环境条件的综合限制。综述水下光照条件、水体和沉积物营养盐等对沉水植物生长影响的研究进展,总结出光照强度、水体氮磷含量、沉积物氮磷含量等单个因子对不同沉水植物物种的作用范围。在生态工程的应用实践中,单一因子的作用阈值会由于因子间的交互作用而产生变化,因此提出多重因素联合影响研究的必要性,以期丰富沉水植物的生理生态学的基础理论,并对生态修复工程实施提供切实的理论依据和实践指导。
The rehabilitation of submerged macrophytes is the key objective for water ecological restoration in aquatic ecosystem.However,the recovery process of submerged macrophytes is often limited by multiple environmental factors and their interactions.The research progress on the effects of underwater light intensity,the nutrient level in waterbody and sediment on the growth of submerged macrophytes was reviewed,and the appropriate ranges of each single factor on different submerged plant species were summarized.The threshold of single factor would change due to the interaction between these factors in ecological engineering applications.Therefore,it is necessary to investigate the combined effects of multiple factors on submerged macrophytes.The further research will enrich the basic theory of physiology and ecology on submerged macrophytes and provide theoretical basis and practice guidance for the implementation of ecological restoration projects.
