基于GIS的区域雨水资源化潜力评价模型研究

Regional rainwater harvesting potential assessment model based on GIS

区域雨水资源化潜力的定量评价对于雨水资源开发利用的宏观决策、规划设计具有十分重要的意义。该文以黄土高原地区为例,系统分析了影响区域雨水资源化潜力的各个因子,确定定量评价区域雨水资源化潜力的各项指标,并运用GIS技术,集成多种来源、多种比例尺和多种类型的数据,建立区域雨水资源化潜力定量评价模型。评价模型对于黄土高原地区雨水资源可持续利用及生态与环境保护具有重要作用。

Quantitative assessment for regional rainwater harvesting potential is very significant for macro decision-making and comprehensive planning of regional rainwater harvesting. Taking the Loess Plateau as a sample region and rainwater resources as research object, the influence factors of regional rainwater harvesting potential were analyzed systematically. Quantitative assessment indices of regional rainwater harvesting potential were defined. And the data with different origins, different scale and different types were integrated using GIS technique. Quantitative assessment model for rainwater harvesting potential was established. The assessment model plays an important role for sustainable utilization of rainwater resources and eco-environmental protection in the Loess Plateau.
