贵州黔西地下水保护区划定及保护措施模型研究

利用地下水流场和溶质模拟软件系统FEFLOW建立地下水数值模拟模型，模拟地下水的流场分布和补给、径流和排泄规律，结合数值模拟结果和流线追踪技术描绘地下水水源地汇流补给集水区域，分级划分地下水水源地保护区范围，提出保护区综合保护措施，以防止地下水源受到污染，保障当地饮水安全，为区域水资源合理开发利用和综合管理提供理论依据和决策工具。

Research on Planning and Protection Model of Groundwater Preservation Zone in Qianxi

By using the advanced finite element software package FEFLOW, the paper establishes a mathematical groundwater model to simulate the groundwater flow in Qianxi County, Bijie, Guizhou Province. With the groundwater flow path line tracing technique, the paper identifies the capture zone of flow for the groundwater sources, based on which preservation zones are delinea-ted. Moreover, protective measures are proposed to protect groundwater from being polluted and to ensure the safety of drinking wa-ter supply. The demonstrative study will not only be the theoretical basis, but also a decision making tools for regional groundwater resources protection, management, rational exploitation and sustainable utilization.
