地下水可持续开采量是允许开采量发展的必然,与允许开采量不同,地下水可持续开采量突出了环境因素,同时强调了地下水资源的可更新和可持续利用性。地下水可持续开采量评价是实现地下水可持续利用的前提。本文在综合痼研基础上,探讨了地下水可持续开采量的内涵与特点,分别从地下水更新能力、环境需水、动态性等方面,综述了目前国内外实现地下水可持续开采量评价的前沿问题及发展动态。
Different from the safe yield, the groundwater sustainable yield is involved environmental factors and places more emphases on its renewability and sustainable exploitation. Firstly, this article discusses the cognition of groundwater sustainable yield. On the basis of abroad and domestic research, and from the perspective of environmental water requirements, renewability, anthropogenic disturbances, etc, it respectively investigates the advances and precursory problems to accomplish groundwater sustainable assessment.
