沉水植物生态修复现状及生长影响因素探究

Current status of ecological restoration by submerged plants and factors affecting plants′growth

沉水植物在湖泊和河流中发挥着重要的生态作用,沉水植物在生态修复中被广泛使用。总结了沉水植物在水体生态修复中的研究现状,重点综述了营养物质、水深、水温、基质和光照等不同环境因素对沉水植物生长的影响,并探讨了这些因素如何综合影响沉水植物的修复效果。结合工程应用存在问题,展望了沉水植物生态修复技术的发展方向。

Submerged plants play an important ecological role in lakes and rivers,which are wildly used in ecological restoration.The current status of submerged plants in ecological restoration of water bodies was summarized;different environmental factors influencing submerged plants′growh,which includes:nutrient substance,water depth,water temperature,substrate,light,and so on,were emphatically elaborated.The effect of those factors on ecological restoration by submerged plants was discussed.Combined with the problems of engineering application,the development direction of submerged plants ecological restoration technology was prospected.
