摘要:清水型生態系統構建技術是在水生態修復技術基礎上發展而形成的,2012年被創造性地運用于大源公園湖(30°42′N,104°2′E)水質治理中。本文通過對大源公園湖2012年2月-2013年4月的水質數據分析得出:(1)湖區水質穩定在地表水II類-III類水平;(2)平均水體透明度在1.8m以上;(3)湖區穩定處于中營養化水平;(4)湖區沉水植物多樣性增加。綜上,清水型生態系統構建技術在大源公園湖中的應用非常成功,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.
