摘要
干旱半干旱地区地下水具有重要的生态价值。本文从这一地区地下水与生态环境之间关系出发,以地下水资源永续利用并与社会经济和生态环境协调发展为目标,探讨了地下水生态价值的定义,分析了地下水引起的表生生态效应及其驱动力,建立了地下水引起的表生生态效应递阶层次评价指标体系。这些研究不仅丰富了水资源生态价值理论,而且对这一地区水资源合理开发利用并与社会经济、生态环境协调发展具有参考价值。
Groundwater has very important eco-value in arid and semi-arid regions. Based on the relationship between groundwater and eco-environment, for the purpose of maintaining sustainable exploitation on groundwater and ensuring coordinated development of society, economy, and ecological environment, this paper discusses the definition on groundwater eco-value, analyzes the eco-effect of groundwater and its main driving factors, and establishes its assessment index system. These not only enrich the eco-value theory of water resources, but also provide reference to sustainable exploitation on groundwater and harmonious development among society, economy, and eco-environment in the regions.
