| 摘 要： | 针对水体富营养化的生态逆境,以个体沉床微生态作为研究的基本单元。即通过控制其非生物和生物成分,局部构建以满足水生植物适生环境为核心的水体生态结构体,由个体到总体,以点带面,从而实现总体生态功能目标的恢复。此法融合了恢复生态学人为设计、自我设计理论,并突出人为干预的主导作用。通过沉床微生态控制体改善水质的正交试验,运用数量化理论分析方法,筛选出最佳组合为陶粒箱+页岩+金钱蒲+雨久花,在静态时TP的去除率可达到(76.6±1.17)%,COD的去除率达到(37.4±2.27)%;在动态时TP的去除率可达到(39.5±1.17)%,COD的去除率达到(16.03±1.41)%。其显著性与可靠性均达到95%以上,此结果可作为两种水体恢复应用时的参考。

| Abstract: | Ecology adversity of waters eutrophication was studied.Local aquatic ecosystem with hydrophyte as the core of microecology structure was built using individual caisson microecology as the basic unit by controlling the living and nonliving components.The method with artificial design and self design theory of restoration ecology makes dominant reaction of human intervention into prominence.Several orthogonal experiments of improving water quality were done using caisson microecology structure,with the optimu... |
