摘要：清水型生態(tài)系統(tǒng)構(gòu)建技術(shù)是在水生態(tài)修復(fù)技術(shù)基礎(chǔ)上發(fā)展而形成的，2012年被創(chuàng)造性地運用于大源公園湖(30°42′N，104°2′E)水質(zhì)治理中。本文通過對大源公園湖2012年2月-2013年4月的水質(zhì)數(shù)據(jù)分析得出：（1）湖區(qū)水質(zhì)穩(wěn)定在地表水II類-III類水平；（2）平均水體透明度在1.8m以上；（3）湖區(qū)穩(wěn)定處于中營養(yǎng)化水平；（4）湖區(qū)沉水植物多樣性增加。綜上，清水型生態(tài)系統(tǒng)構(gòu)建技術(shù)在大源公園湖中的應(yīng)用非常成功，為其他景觀湖水治理治理工程提供參考。

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.
