摘要：景观水由于设计条件的限制等诸多因素，简单的套用宏观生态法维持水质，结果适得其反，导致亲水区域减少、蚊蝇滋生、。建议采用生态法处理景观水体时，通过造流复氧强化微观生态系统功能，可以取得相得益彰的效果。

tract: Macrocosmic ecosystem was applied which had achieved perfect effects in many man-made lakes. However, due to some disadvantages (e.g. unreasonable waterscape designs), many negative effects, such as reduction of open water area, mosquito breng, uncontrollable aquatic plants growing, low visibility, and difficult cleaning, have appeared. Functions of microcosmic ecosystem could be enhanced by making flow and aerating which resulted in high water quality when ecological treatment was applied in man-made lakes.

一、 前言
近年来，随着人们生活水平的提高，亲水性生活环境成为一大需求，2003年底上海市区住宅景观水水面积就达100万平方米。水景住宅存在的问题也逐渐的显露出来，如补充水源、处理成本、后期管理等。尤其是在人工湖的治理方面，一直以来都没有得到很好的解决，常有业主因为人工湖水质恶化等问题与物业发生矛盾，甚至诉诸法律，因此人工湖的治理和管理也越来越受到人们的关注。
二、 景观水处理现状
1． 循环过滤在水处理工艺中通常称之为强制水处理方式。采用循环过滤通常会出现以下问题：
