摘要/Abstract

摘要： 精确评价乡村社会-生态系统脆弱性并识别其空间分异特征是合理制定国土综合整治规划和精准施策、促进乡村可持续发展的基础。该研究针对效率模型权重分配影响评价结果的精确性问题，引入灾害脆弱性理论的压力冲击因果链分析框架，界定乡村社会-生态系统脆弱性内涵和形成机理，构建社会-经济-环境-压力-状态-响应（SEE-PSR）模型的致脆效率评价指标体系，采用3种效率评价模型对2018年上海市青浦区184个行政村进行评价和比较，分析其空间分异特征并将研究结果运用于国土综合整治时空配置实践。结果表明，乡村社会-生态系统在环境、社会、经济等压力变化下所表现出的承脆体状态和综合应对能力过程符合"输入-产出"的系统致脆效率；采用熵权对抗交叉数据包络分析模型（EW-ACE-DEA）对乡村社会-生态系统脆弱性进行评价，结果更具可信度和精确性；2018年该区行政村社会-生态系统脆弱性均值为0.595，全区值域范围为［0.404，0.787］，且空间上呈现由东向西逐渐降低的变化趋势；采用乡村脆弱性等级-脆弱性空间集聚类型的综合配置法，可合理安排该区国土综合整治时序，上海市青浦区国土综合整治时空配置类型可划分为5类。该研究丰富了乡村地理学理论，可为乡村区域治理和区域可持续发展提供决策依据。

Abstract: The accurate evaluation of rural vulnerability and identification of its spatial differentiation is the basis for rational development planning and accurate implementation of the strategies to promote rural revitalization. Focused on the problem that the weight distribution of efficiency model affects the accuracy of evaluation results, this research studied the framework of stress shock chain analysis with the introduction of disaster vulnerability theory to define the regional social-ecological system vulnerability connotation and formation mechanism. Three kinds of efficiency evaluation models were used to evaluate and compare 184 administrative villages in Qingpu District of Shanghai in 2018, and the comprehensive ranking method of ‘vulnerability grade-fragile spatial agglomeration characteristic-fragile size’ was used to design the sequence of integrated territory consolidation. The obtained results are as follows:(1) The formative process of formation of the combined capacity of the regional social-ecological systems to respond to the differences in vulnerability, resistance, adaptability and resiliency in combination with the change of ‘environment-socio-economic’ pressure was consistent with the vulnerability efficiency of ‘pressure input-capacity output’. (2) The EW-ACE-DEA model based on entropy weight aggregation was more reliable and accurate for the evaluation of regional social-ecological system vulnerability. In the year of 2018, the average social-ecological system vulnerability of the administrative village in this region was 0.595, the range of the whole region was[0.404, 0.787], and the spatial trend was gradually decreasing from east to west. (3) According to the comprehensive ranking method of the regional vulnerability grade and the spatial agglomeration characteristic and value of vulnerability, the sequence of integrated territory consolidation in this area can be reasonably planned. The comprehensive regulation of administrative villages in Qingpu District can be divided into five categories:short-term (33 villages), short-medium-term (45 villages), medium-term (41 villages), medium-long-term (38 villages) and long-term (27 villages). The research results could enrich the theory of rural geography and provide decision basis for rural regional governance, rural revitalization and regional sustainable development.
