Abstract: Vulnerability assessment framework in sustainability science has properties of multi-scale, multi-element, multi-flow and multi-cycle, so vulnerability assessment is a new research paradigm in the realms of global environmental change and sustainable development, and provides an effective tool for the study of interaction mechanisms and processes of coupled human-land system. Based on the dependence of economic development on resources, and the instability in employment, and the ecology being relatively disrupted, the vulnerability assessment indexes of Anshan city are established. By using the set pair analysis and the entropy method, the essay analyzed the sensitivity, response capacity and vulnerability level of the economic system, as well as the employment system and the ecosystem. Then the vulnerability of human-land system of Anshan city are tested and the evolution of vulnerability characteristics during 1990 to 2009 has been revealed.
The relationship of human-land system of Anshan city belongs to the lower sensitivity and higher response capacity type. In comparison with other resource-based cities in Northeast China, the human-land stability of Anshan city is stronger, and the vulnerability is relatively weak, which means that Anshan city has lower sensitivity and better response capacity to the complicated human-land system. The sensitivity of Anshan city has a declining trend, and the economic sensitivity is bigger than the environmental sensitivity and the social sensitivity. The response capacity of Anshan city shows a rising trend, and the environmental system is more evident than the social system and the economic system. There is a rising trend for vulnerability of Anshan, and economic system is most vulnerable. The paper reflects that Anshan city has better potentials to develop a sustainable economy, but attention should be paid to lowering the sensitivity of the economic system and to increasing the response capacity.

Key words: Anshan city, human-land system, response capacity, sensitivity, set pair analysis, vulnerability
