【 摘 要 】

This paper aims to develop a set of valid and reliable indicators to evaluate the regional land subsidence disaster vulnerability. The proposed indicator system can provide effective theoretical support for further land subsidence risk evaluation and risk management. This study transfers the qualitative analysis of land subsidence vulnerability to quantitative evaluation by developing a universal land subsidence vulnerability indicator system and outlining a corresponding vulnerability analysis framework. The land subsidence vulnerability analysis in Xixi-Chengnan area, Jiangsu Province, China used as the case study to prove the applicability and the simplified use of the proposed system. Based on the flexibility of the proposed universal indicator system, indicators can be added into and deleted from the system, according to the actual situation in a certain study area.
