沙漠化脆弱性的概念与评价

The Concept and Assessment of Desertification Vulnerability

全球变暖背景下,气候变化和人类活动对沙漠化的影响成为可持续发展研究的热点问题。首先,本文基于对脆弱性概念发展的简要回顾,结合气候变化研究中的脆弱性,提出沙漠化脆弱性的概念和理论体系。其次,梳理国内外关于脆弱性评价的文献,依据沙漠化系统的特点阐释了沙漠化脆弱性评价体系、评价内容及评价方法。最后,列举沙漠化脆弱性研究中需要解决的问题,明确中国沙漠化脆弱性评价的未来特点和趋势。

With the background of global-warming,impacts upon desertification resulting from various factors,including climate change and human activities,have become a hot issue for sustainable development.In this paper,the concept of desertification vulnerability and its theoretical system was proposed based on the brief review regarding evolution of vulnerability and climate change vulnerability.Then,according to literatures on vulnerability assessment and the character of desertification system,we also interpret the theoretical system of desertification vulnerability assessment,as well as the content and method of it.Finally,we have to pay attention to several problems to be solved in research into desertification vulnerability later on and to identify the features and trends of desertification vulnerability,along with future challenges for properly assessing it.
