title: [Treatment effect of eutrophication restoration project for Lichee Lake in Shenzhen].
abstract: Based on 9-month monitoring field data, this paper analyzes the variation of chlorophyll-a (Chl-a), total phosphorus (TP), total nitrogen (TN) and transparency (SD) in different sub-lake districts in order to study the treatment effect of eutrophication restoration project in Lichee Lake in Shenzhen. The statistical results show that, the average of TP and TN for whole lake were below 0.1 mg x L(-1) and 1.5 mg x L(-1) respectively, the average of Chl-a of north lake district and east lake district were 16.77 microg x L(-1) and 21.45 microg x L(-1) respectively, lower than that of south lake district (35.83 microg x L(-1) and west lake district (32.69 microg x L(-1)), and the average of SD for whole lake was greater than 0.5 m. During the 9-month operation of the restoration project, the average water quality satisfied the National Standard IV for surface water and the water was improved from hypereutrophic status to eutrophic status in Lake.
