摘要: 为实现对陕西省田市镇及其周边地区地下水的合理开发利用、科学管理和有效保护,以全国地下水功能区划分技术大纲为基本依据,结合该地区地下水资源的分布特点、水文地质条件、地下水开发利用现状及生态环境保护需求,构建了该区地下水功能区划分指标体系。采用综合指数模型,利用MapGIS技术,将研究区地下水功能区划分为适宜开采区、适度开采区及禁止开采区。研究成果可为田市镇及周边地区制定和实施地下水系统的保护方案、指导地下水资源合理开发利用提供科学依据。Abstract: In order to achieve reasonable exploitation, scientific management and effective protection of groundwater in Tianshi Town and its surrounding areas in Shaanxi Province, based on the technical outline for the division of national groundwater function zones, the authors established the index system of groundwater function division, combing with the distribution characteristics of groundwater resources, the hydrogeological condition, the current situation of the groundwater development and utilization and demands for ecological and environmental protection in the region. The comprehensive exponential model and MapGIS technology were adopted. The groundwater function in the study area was classified as suitable mining area, moderate mining area and no-mining area. The research results can provide scientific basis for formulating and implementing the protection scheme of groundwater system and exploiting groundwater reasonably in Tianshi Town and its surrounding areas.
