水资源脆弱性及其定量评价

Concept and Quantitive Assessment of Vulnerability of Water Resource

总结了水资源脆弱性的研究领域、研究进展及其目前存在的一些问题 ,认为在水资源脆弱性方面的研究比较薄弱 ,应拓宽范围 ,加强理论与实际应用研究。参考目前水资源脆弱性研究的成功与不足 ,重新定义了水资源脆弱性的概念 ,用来描述在发生水灾、旱灾或水资源受到过度开发或污染时 ,系统本身所表现出的结构和功能易于受到破坏的性质、缺乏恢复到初始状态的能力等 ,扩展了水资源脆弱性的研究范围。为了便于进行水资源脆弱性评价 ,建立了易于操作、可比性强、综合全面的指标体系 。

The domain and advancements of vulnerability are concluded. It is believed that the research is weak in aspect of water resource and that the scope should be widened and the academic and applied research should be strengthened. The vulnerability of water resource is redefined to describe the ability of the system to recover its original structure and function when it is damaged. The research scope is widened, and a integrative index system is built to express the vulnerability of water resource, and a quantitative assessment method is brought forward.
