中文摘要	针对已修复生态地区人地系统脆弱性及其干扰因素的研究,对实现区域可持续发展具有重要的意义。采用综合指数评价方法,从生态、经济和社会3个方面确定9项分指数、选取24个具体指标,构建了典型沙漠化逆转区人地系统脆弱性评价指标体系,对盐池县人地系统脆弱性进行了定量评价,运用障碍度模型分析了盐池县人地系统脆弱性的障碍因素。结果表明:盐池县经济、生态和社会系统脆弱性均呈波动走势,但又表现出相应的阶段特征。经济系统脆弱性伴随经济结构的转型,呈现先降后升的趋势。生态系统受气候和政策双重影响,以2000年为节点呈现前后不同的波动走势。社会系统在研究时段呈明显的线性递减趋势。盐池县人地系统脆弱性2000年前呈高位波动态势,2000年后整体波动递减,平均降幅32.06%;主要障碍因子为:欠合理的产业结构、特殊的地理区位、生态治理力度和社会保障水平。建议:加快推进产业结构转型升级;生态保护与开发并举,践行绿色发展;减小贫富差距,继续加强社会保障建设。
英文摘要	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.
