A brief description of the conception and the importance of sediment and aquatic macrophyte in the lake ecosystem was given in this paper. The physical and chemical properties of sediment that had an effect on the growth of aquatic macrophyte, and aquatic macrophyte that affected the release of sediment nutrient salt and sediment resuspension were summarized. Based on reports of researches, the results suggested that different types of lake sediment determined the growth state of aquatic macrophyte; suitable range of nutrient salt can promote the growth of aquatic macrophyte; and different kinds of aquatic macrophyte had difference in tolerance of sediment nutrient salt. Aquatic macrophyte can promote sediment deposition and reduce resuspension. The presence of aquatic macrophyte had a notable effect on phosphorus activity in the sediment. The restoration of contaminated sediment can provide a good condition for the stabilization and growth of aquatic macrophyte. It was favorable to the restoration and reconstruction of aquatic macrophyte in the eutrophic lake.%简要阐述了湖泊生态系统中底质和水生植物的概念及重要性,综述了底质理化性质对水生植物生长的影响,以及水生植物对底质营养盐的释放和底质再悬浮的作用.通过大量的研究综述回顾论述了不同的湖泊底质类型在一定程度上决定了水生植物的生长状态,适合的底质营齐盐范围能促进水生植物生长,不同水生植物对底质营养盐的耐受性有差异.水生植物能促进底质沉降并减少再悬浮,水生植物的存在对沉积物中磷的活性有显著的影响.污染底泥的修复能为水生植物的立地与生长提供了良好的底质条件,有利于富营养化湖泊水生植被的恢复与重建.
