Research on the assessment of the vulnerability of man-land system and its disturbing factors in restored ecological areas is of great significance to improve regional quality and promote sustainable development. In this study, using a comprehensive index assessment method, we selected 9 subindexes involving 24 specific parameters from 3 aspects (ecological system, economic system and social system) to construct a comprehensive index system for the assessment of Yanchi County’s vulnerability. The obstacle factors of man-land system vulnerability in Yanchi County were analyzed by using the obstacle degree model. This study revealed that the vulnerability of Yanchi County's economic, ecological and social systems fluctuates, but it also shows corresponding stage characteristics. With the transformation of economic structure, the vulnerability of economic system shows the trend of decreasing first and then rising. The ecosystem is affected by climate and policy, and shows different fluctuation trend with the transition of 2000. The social system showed an obvious linear decreasing trend during the research period. The vulnerability of Yanchi County’s man-land system fluctuated at a high level before 2000, and declined gradually after 2000, with an average decline of 32.06%. The main obstacles are unreasonable industrial structure, special geographical location, ecological governance and social security level. According to the research results, the following suggestions are put forward: firstly, accelerate the transformation and upgrading of industrial structure; secondly, combine ecological protection and development to practice green development; thirdly, reduce the gap between rich and poor, and continue to strengthen social security construction.

Key words: desertification reversal area, man-land system vulnerability, obstacles, Yanchi County
