摘 要:以甘肃省为例,从脆弱性的角度出发,运用综合评价方法构建社会—生态系统脆弱性评价体系,探寻甘肃省脆弱性的空间分布格局及驱动机制,为保护西北地区的生态屏障提供理论依据。结果表明:甘肃省的区域脆弱性程度呈自南向北递增趋势;中等脆弱性地区占甘肃省的面积最大,达到36.1%;社会因素与自然因素对脆弱性起共同作用,但社会因素为主要的驱动因子;甘肃省的地理分区与脆弱性分区在空间上基本保持一致。最后依据不同区域各自的特点提出了降低脆弱性的有益意见。Vulnerability is an important research field of global environmental change and hot issues. The article takes Gansu Province as an example, starts from the point of view about the vulnerability, uses the comprehensive method of assessment to construct the evaluation system of vulnerability of Social-ecological system, explores the space of distribution of vulnerability and driving mechanism in Gansu Province, to provide theoretical basis for the protection of the ecological barrier in Northwest China. Results show that: the degree of vulnerability of Gansu Province shows increasing trend from south to north, the largest area accounted is moderate vulnerability, up to 36.1%. Social and natural factors both effect the vulnerability, But the social factors as the main driving factors. The geographical division in Gansu Province keeps the consistent in space with vulnerability division. Finally, according to the characteristics of different regions, put forward the beneficial opinions to reduce the vulnerability.
