摘　　要：采用人工模拟方法,将一种生态塘与人工湿地的新型复合模式应用于北京某公园的湖水经社会景观循环后成为微污染水体的预处理,形成一个景观水体型生态屏障,以削弱微污染水体对自然受纳水体的不利影响。试验进行5个月的结果表明,景观水体型生态屏障对污染物去除效果良好,夏季对COD、TN和TP去除率分别达到了65.2%～73.6%、62.5%～66.0%和70.0%～80.0%,出水水质达到GB 3838-2002的地表水Ⅲ类水质标准;秋季处理后出水COD、TN和TP的含量也稳定在地表水Ⅳ类水质标准,并营造了具有环境美学与观赏价值的人工景观水体,发挥了水资源效益与积极的生态环境效应。As the lake water of Yuyuantan Park of Beijing has became slightly polluted water after the social landscape cycles and the micro-polluted water run into the Kunyu River, the research adopts a method of manual simulation to treat the micro-polluted water, with a new-type of compound pattern we call landscape-designed ecological barrier which consists of ecological pond and constructed wetland is applied to the pretreatment of this micro- polluted water. In order to weak the adverse effects of micro-polluted water on natural water, this new-type of compound pattern forms a water-based landscape ecological barrier. After 5 months experiment, site test results show that the landscape-designed ecological barrier has a better removal of pollutants. The removal rates of COD, TN and TP respectively reached 65.2%-73.6%, 62.5%-66.0% and 70.0% - 80.0%. And the effluent quality can reach Ⅲ water-quality of Environmental quality standards for surface water （GB 3838--2002）. In AuttLmn, the post treatment removal rotes of COD, TN and TP of effluent content sustain at IV water-quality of Environmental quality standards for surface water（GB 3838 --2002）, and it builds with environmental aesthetics and visual value of cultivated landscape water, which has played a positive benefits of water resource and eco-environment effects.
