摘要
针对目前景观水体维护中发生的水质恶化问题,通过分析其污染的原因和水质净化的原理,提出了景观水体的防治必须以生态学原则为核心.对污染物的输入和输出进行合理调控。其中,污染物有效输出的关键在于良性水生生态系统的营造。同时,分析了景观水体的维护成本和经济收益。
The paper delt with major problem in maintaining landscape waterbody which is deterioration of water quality. Through analyzing the cause of pollution and the principle of purification following the ecology principle as the core to adjust the input and output of pollutants. The key to output the pollutants effectively is to construct a healthy aquatic-ecosgstem. At last, the paper analyzed the maintenance cost and economic profits of the landscape water.
