%X 将搭载土著生态组成的叠层生境系统 (Laminated Habitat System, LHS) 嵌入富营养化景观塘池, 以发生水华的氮、磷经验阈值为基准, 研究了高时空分辨条件下LHS对塘池水质及其灰水足迹“汇”变的作用, 并综合分析了实验生境的改善. 结果表明: 室外静态条件下, 嵌入LHS至模拟景观塘池20 d后, 塘池水质改善明显, TP去除率可达81.01%, TN, NH4+-N, NO3--N去除率分别为77.10%, 88.82%, 84.12%; CODCr的处理率达67.51%; Chl.a质量浓度降至0.98 μg·L-1; Chl.a质量浓度及浊度降至了初始值的10%以下; 模拟景观塘池灰水足迹降至初始态的22.9%. LHS利于景观塘池水质和生态系统改善, 益于藻型塘池向草型塘池转变及塘池灰水足迹“汇”增. 本研究提供了灰水足迹理论指导下的景观塘池生态修复新思路.</br>The Laminated Habitat System (LHS) composed of indigenous species was designed and embedded into a Small Experimental Landscape Pond (SELP). The variation of water quality, eco-habitat and the sink of grey water footprint (WFgrey sink) for the SELP at high spatiotemporal resolution were measured statically outdoor for 20 days. The results showed that the removal efficiencies of TP, TN, NH4+-N, and NO3--N reached 81.01%, 77.1%, 88.82% and 84.12%, respectively, while the removal efficiency of CODCr reached 67.51%, and the concentration of Chl.a decreased to 0.98 μg·L-1. The turbidity reduced to about 10% of its original level, while 22.9% for the sink of grey water footprint. The LHS acted excellently in improving water quality and rehabilitating the eco-habitat, and promoted the eco-succession of SELP from algal-dominated to macrophyte-dominated. Moreover, this study provided a new idea for Landscape Pond ecology maintenance in the light of Grey Water Footprint theory.
