摘要：清水型生态系统构建技术是在水生态修复技术基础上发展而形成的，2012年被创造性地运用于大源公园湖(30°42′N，104°2′E)水质治理中。本文通过对大源公园湖2012年2月-2013年4月的水质数据分析得出：（1）湖区水质稳定在地表水II类-III类水平；（2）平均水体透明度在1.8m以上；（3）湖区稳定处于中营养化水平；（4）湖区沉水植物多样性增加。综上，清水型生态系统构建技术在大源公园湖中的应用非常成功，为其他景观湖水治理治理工程提供参考。

Abstract:The ecological restoration techniqueto new man-made lake is dependent on the basis of traditional ecological restorationtechnique to contaminated lake，and it was creatively used in Dayuangongyuan lake(30°42′N,104°2′E) water environment engineering. Through analyzing the waterquality data of Dayuangongyuan lake from March 2012 to April 2013, the following conclusions are: (1) according to Environmental Quality Standards for SurfaceWater, the lake water quality remains stable at II-III level; (2) the average Secchidisk depth is above 1.8m; (3) accordingto TLI(∑) Standards,the lake water quality remains stable at meso-trophication;(4) Diversityof submerged plants increased. To conclude, the ecological restoration technique to new man-madelake was successfully applied in Dayuangongyuan lake. The case can providereference for other new man-made lakes water environment engineering.
