摘要: 脆弱性理论与方法已成为研究复杂社会生态系统可持续发展的有力工具。通过构建脆弱性评价指标体系,研究振兴东北战略实施以来东北西部农牧交错带社会生态系统脆弱性时空演变特征。结果如下。1)东北西部农牧交错带社会生态系统脆弱性总体呈下降趋势,平均脆弱性得分由2005年的1.343下降到2015年的1.197;适应能力的提高是地区脆弱性降低的主要原因。2)脆弱性水平呈"西南高、东北低"、"北部稳定、中南部下降"的时空分异特征。3)低应对能力是地区脆弱性的主要特征,而各脆弱类型呈差异化分布态势。在当前东北地区粮食结构调整背景下,针对不同地区的脆弱性特征,实施差异化的应对策略是保证地区可持续发展的有效途径。

Abstract: The vulnerability study has become a powerful tool for the comprehensive analysis of the social-ecosystem. This paper analyses the spatio-temporal characteristics of vulnerability of the social-ecosystem in the agro-pastoral ecotone in western Northeast China by constructing a vulnerability evaluation index system. The results are given as follows. 1) The vulnerability level in the agro-pastoral ecotone in western Northeast China totally demonstrated a downward trend from 2005 to 2015, and it evolved from 1.343 in 2005 to 1.197 in 2015. 2) The vulnerability in the southwest of the study area is at high level while in the northeast it is relatively low. Additionally, it stays stable in the north while declines in the south and in the central region. 3) The low response ability is the main characteristic in the agro-pastoral ecotone and the various vulnerable types demonstrate differential distributions. Under the background of the current grain structure adjustment in Northeast China, it is an effective way to ensure the sustainable development of the region to implement different strategies according to the different characteristics.

Key words: vulnerability, social-ecosystem, agro-pastoral ecotone, spatio-temporal characteristic, the western Northeast China
