湖泊水生植被恢复物种选择及群落配置分析

介绍了水生植物恢复的常用物种及生活型 ,并从群落配置的物种数 ,群落的空间配置及节律匹配等方面对水生植物群落的优化配置进行了分析和研究 ,结果表明 :1 )在水生植物群落恢复实践中 ,无论从经济角度考虑 ,还是从可操作性出发 ,均应优先考虑选择少量先锋物种 ,先恢复生态系统的基本结构和功能 ,随着生境条件的不断改善 ,逐步栽种新的物种 ,增加物种的多样性 ;2 )根据湖相生态系列在空间生境梯度上的变化 ,按水生植物生活型配置群落是群落配置的基本出发点 ;3)应根据水生植物的季节差异合理配置群落 ,使植物种群在生长期上密切衔接 ,形成常绿人工水生植被 ,这样在冬季也能较好地发挥对湖泊的净化功能

Analyses on species selection and community collocation of macrophyte in lake restoration

This paper introduces basic species and its living type of the macrophyte restoration and analyzed rational distribution of macrophyte community from aspects of species number, space distribution and rhythm. And we conclude three viewpoints. In the first during the process of macrophyte restoration, economy and maneuverability factors should be considered. It is better to select some pioneer species firstly, resume basic structure and function of lake ecosystem and improve species diversity gradually. Then collocating macrophyte community bases on living type according to lake ecological series change with space habitat gradient. At last in order to make macrophyte community exert purification function well in winter, macrophyte community should be collocated properly based on growth period to form evergreen artificial macrophyte community.
