【摘要】 从经济、资源环境和社会三方面构建城市脆弱性综合评价体系,运用综合指数法和GIS手段对东北振兴政策实施以来东北地区的城市脆弱性时空格局演变进行分析。研究发现:时间序列上,东北振兴以来,东北地区城市脆弱性演化历程可分为高脆弱性主导阶段(2003—2006年)和低脆弱性主导阶段(2007—2011年),城市脆弱性总体上呈现减小趋势,且区域差距不断缩小;空间演化上,城市脆弱性空间格局日趋均衡,高脆弱性城市呈现"扎堆"聚集的特点,低脆弱性城市与东北经济空间格局基本吻合,省际之间脆弱性程度内蒙东部最小,其次是辽宁和吉林,黑龙江最高,就区内差异而言,除黑龙江区内差距扩大外,其他三省均波动下降;区域中心城市的脆弱性不断降低且差距不断缩小,资源型城市的脆弱性程度下降幅度较大,内部呈现不平衡的特点。国家战略调整与重要规划实施、区域产业调整与财政金融扶持、区域开放带动与空间布局优化以及资源型城市转型政策是东北振兴战略对城市脆弱性时空格局演变的重要作用机制。更多还原

【Abstract】 By constructing comprehensive evaluation system of urban vulnerability, using compensive index method and the visualization of GIS,this paper analyzed the spatial-temporal evolution of Urban vulnerability of the Northeast region in China since Northeast Revitalization.Results are shown as follows.In the time series, the evolution of vulnerability can be divided into a high- vulnerability leading stage(2003- 2006) and low- vulnerability leading stage(2007- 2011). The vulnerability of northeastern cities generally decreased and the vulnerability gap shrunk. The spatial pattern of urban vulnerability has become increasingly balanced. High- vulnerability cities show the characteristics of"clustering". Lowvulnerability cities and the northeast economic area basically match. Among provinces, eastern Inner Mongolia has the lowest vulnerability, followed by Liaoning and Jilin, while Heilongjiang has the highest degree of vulnerability. In terms of differences between areas, the other three regions have experienced decreasing volatility at the same time that the Heilongjiang area gap is widening.The degree of vulnerability of the regional central city is also decreasing, and the gap is also shrinking. Resource-based city have experienced a larger decline in vulnerability. The internal gap is unbalanced.Mechanisms of effect which the strategy of revitalizing northeast has on temporal and spatial pattern of city vulnerability evolution consist of several aspects, i.e. the adjustment of national strategy and the implementation of Important plans,the adjustment of regional industries and fiscal and financial support, the drive of regional opening policies and the optimization of spatial arrangement, the transformational policies of the resource type cities and so on.更多还原
