从生态学观点看湖泊藻类控制的技术体系

富营养化水域中,引起湖泊水华和海洋赤潮的藻类疯长被称为“生态癌”。从生态学的观点分析了湖泊退化的原因,提出生态系统内物质循环的规模是否在自然环境条件所能支持的限度内是分析湖泊治理成效的判据,而将参与物质循环的过量物质从湖泊中移出则是湖泊治理技术的根本着眼点。文章还从生态学的视角架构了湖泊藻类控制的技术体系,并对每种技术在体系中的作用做了分析,由此提出了湖泊治理的技术路线。

To Perceive the Technical System of Lake Algae Control from Ecological Point of View

In eutrophic lake, the excess propagation of algae is being called ecological cancer. From ecological point of view, to analyze the cause of degradation of eutrophic lakes. How efficiency of lake treatment can be judged by seeing whether the scale of matter circulation in ecosystem is under the sustainable limit of natural environmental conditions. Removal of the excess circular matter from the lake ecosystem is the fundamental law of lake treatment technology. In view of ecology, this paper set up the technical system of algae control, and analyzed the function of every technique in the technical system. According to the foregoing analysis, the technical course of lake treatment has been proposed.
