摘要
摘要: 为了解淮河流域内水生植物特征及分布成因,采用野外调查和室内分析相结合的方法,对淮河流域(河南段)水生植物的组成、水体和土壤环境特征及两者间相关性进行了分析。结果表明:流域内共有水生植物51 种,其中挺水植物种类最多,共计28 种,占物种总数的54.9%;沉水植物12 种,浮叶植物10 种,两者共占物种数的43.1%;漂浮植物仅有浮萍1 种。主要群落类型共14 种,其中沉水植物5 种,挺水植物6 种,浮叶植物3 种。群落间各环境因子变异较大,其中以水体铵态氮、硝态氮、总氮、总磷、可溶性磷等变化最显著。典范对应分析(CCA)结果表明,水体环境因子如总磷、可溶性磷酸盐、铵态氮和溶解氧是决定该区域水生植物分布的关键环境因子。
Abstract: In order to explore community characteristics and distribution of aquatic macrophytes in the Henan section of Huaihe River Basin and causes, field survey in addition to in-laboratory analysis was carried out of composition of aquatic macrophytes, and characteristics of the water and the soil environment and their relationship in the basin. Results show that a total of 51 species of aquatic macrophytes were detected, including 28 species of emergent plants, 12 species of submerged plants and 10 species of floating-leaved plants, 1 species of floating plant, which accounts for 54.9%, 23.5%, 19.6% and 2.0% of the total, respectively. They formed 14 types of communities, of which 5 were dominated with submerged plants, 6 with emergent plants and 3 with floating leaf plants. The communities varied sharply in environment, especially factors, like NH4+-N, NO3--N,TN,TP and PO43- in the water.CCA reveals that water envionment factors,such as TP, PO43-,NH4+-N and DO concentrations, were the key factors determining distribution of the aquatic macrophytes in the Huaihe River Basin.
