摘　　要：人造生态湿地根孔施工技术具有经济实用、环保高效等优点,目前在我国水环境治理、水源地水质保护方面得到了充分运用,并取得了较好效果,该方法主要是通过人工模拟自然环境中芦苇根孔结构的分布情况,在人造生态湿地建造前期以人工植造芦苇为主,辅以玉米秸秆和菜籽秸秆作为生态湿地的介质填料,在人造湿地土壤亚表层建造以芦苇和秸秆为介质的大孔隙结构,湿地内的原水通过植物根孔结构的过滤净化后,氮、磷、钾、铁、锰等元素含量显著下降,水质得到了质的提升。The construction technology and methods of artificial ecological wetland root holes have been fully applied in water environment management and water quality protection of water sources in China,and have achieved good results.It mainly simulates the distribution of reed root pore structure in the natural environment through artificial simulation.In the early stage of the construction of artificial ecological wetlands,artificial planting of reed is the main method,supplemented by corn straw and rapeseed straw as the medium fillers for the ecological wetlands.A large pore structure with reed and straw as the medium is constructed in the sub surface layer of the artificial wetland soil.The raw water in the wetland is filtered and purified by the plant root pore structure,and its nitrogen,phosphorus,potassium The content of elements such as iron and manganese has significantly decreased,and the water quality in the wetland has been qualitatively improved.This technical method has the advantages of economy,practicality,environmental protection,and efficiency,and has been fully applied in the construction of water source protection projects in the western part of Tongxiang City,Jiaxing,Zhejiang,with significant results.
