摘要:
在参阅大量文献的基础上，界定了水环境压力分区的内涵，并从人口压力、社会经济压力、水资源压力、水环境污染压力和生态环境压力方面初步建立了水环境压力分区的指标体系；以漯河和平顶山为研究对象，运用GIS技术在提取研究区域子流域单元的基础上建立了子流域单元表征指标数据库，并通过相关分析方法选择出人口密度、单位面积水资源量和产业结构作为研究区域的分区指标；结合GIS技术，建立了研究区域9种聚类方案，并运用PFS方法选择出了最优聚类个数；在保证湖库节点完整性的基础上对最优聚类结果进行调整，最终将研究区域分为6类11个区，并分析了各分区的特点，为区域水环境管理目标与措施制定提供了科学依据和决策支持。
Abstract:
The concept of water environmental pressure regionalization is defined on the basis of a large of references and the indicator system is set up basically from population pressure, social economy pressure, water resource pressure, water environmental pollution pressure, ecological environment pressure. The expression indicator database of the sub-watershed is established on the basis of sub-watershed extracted using GIS technology in Luohe and Pingdingshan as the research site, and then, population density, unit area water quantity and industrial structure are selected for regionalization indicators through the correlation analysis method. Nine kinds of clustering schemes of the study areas are built up with GIS technology, and the optimal cluster number is selected using PFS method. The optimal cluster scheme is adjusted in guarantee lake integrity basis, and finally, the study area is divided into six types of eleven regions, and the characteristic of each region is analyzed, which provides the scientific basis and decision support for making regional water environmental management objectives and measures.
