河流类型划分及水生态环境治理技术研究

Research on River Type Division and Water Ecological Environment Management Technology

我国各个层级流域的水污染态势具有时空差异性,为了强化水系统布局和管制,解决治理和修复技术选择盲目性的问题,促进时序安排更加合理,有效弥补研究中存在的不足,因而构建了相关设计方法。以某一河流流域为例,基于水资源以及水生态等建立分类指标体系,采用系统聚类方法对河段单元进行划分,并根据决策树判别准则,以需求性及稳定性分析为切入点,指出不同技术适合引入和运用的时段。通过本文的探讨,能够为更好地促进健全分类方法体系提供思路,为生态修复与河道治理等提供参考,并希望能为相关研究起到一定借鉴作用。

The situation of water pollution in various river basins in China has spatial and temporal differences. In order to strengthen the layout and control of the water system, solve the problem of blindness in the selection of treatment and remediation technology,make the timing arrangement more reasonable, and effectively make up for the shortcomings of the research institute, the design method is constructed. In a river basin, as an example, based on water resources and water ecological classifi cation index system, systematic classifi cation method to river section unit, according to the decision tree criterion, demand and stability analysis as the breakthrough point, points out the introduction and application of different technology, in short, aims to provide ideas to better promote the classifi cation method system, provide reference for ecological restoration and river management, and hope toplay a reference role for related research.
