地表水资源脆弱性:概念、内涵及定量评价

总结了资源环境科学脆弱性研究领域、研究进展及其存在的问题,认为水资源脆弱性研究比较薄弱,南方地表水资源脆弱性研究尤甚。借鉴脆弱性相关研究成果,结合南方地表水资源系统的特点,提出了地表水资源脆弱性的概念,分析了其脆弱性的内涵以及影响地表水资源脆弱性的因素。认为地表水资源脆弱性包括水质和水量2个方面,从脆弱性构成因素上来看它们都可以分解为自然脆弱性、人为脆弱性和承载脆弱性。构建了一个评价地表水资源脆弱性的多用途指标体系。最后,并给出了一种简便易行的地表水资源脆弱性评价方法。

Concepts of Vulnerability of Surface Water Resource and Its Quantitative Assessment

The domain,advancements and existed problems of research on vulnerability in the field of resources and environmental science are concluded.It is believed that research on vulnerability is weak in aspect of water resource,especially surface water resource in South China.After reviewing research on vulnerability in the field of resources and environmental science,a concept of vulnerability of surface water reflecting the characteristics of surface water resource system is put forward for the first time.Then the meaning and contributing factors about vulnerability of ground water are analyzed.It is believed that vulnerability of ground water includes two aspects of water quality and quantity,which all can decompose as natural vulnerability,artificial vulnerability and burdening vulnerability.A multipurpose index system is built to express the vulnerability of ground water resource.A quantitative assessment method is brought forward in the end.
