流域环境流量管理分区方法研究——以浑河流域为例

环境流量管理分区对识别流域各地区的环境流量管理要求,合理配置河流环境流量,协调社会-生态竞争性用水具有重大意义。本文结合管理结构体系,统筹考虑社会-自然两大属性,构建流域分区指标体系;利用聚类分析算法以及布尔运算法结合指标体系对管理流域进行划分,建立了一种区划管理分区的方法。以浑河流域为例,按划分方法将浑河流域划分为5个环境流量管理分区。结果表明:分区方法切实可行,利于简化流域整体管理复杂程度;每个分区具有独立完整的管理结构体系;环境流量管理分区特征鲜明,利于各区管理目标的制定。

Zoning methods of environmental flow management region: A case study of Hunhe River Basin

Building environmental flow management zones is of vital importance to identification of environ-mental flow management requirements in various regions of the watershed, to rational allocation of river en-vironmental flow, and to coordination of social ecological competitive water use. Based on the management structure system,a new method for zoning management district is established in this paper,considering the two attributes of society and nature, and using clustering analysis algorithm and Boolean operation method. By taking Hun River Basin for example, the whole basin is divided into five environmental flow manage-ment zones by the new method. The result indicates that the new method is feasible and is beneficial to simptification of the complexity of watershed management. Each zone has an independent and complete man-agement structure system with distinct characteristics, which is conducive to the development of manage-ment objectives.
