摘要
资源型城市作为一类特殊类型的城市,其脆弱性涉及资源、生态环境、经济和社会等多个方面。探讨资源型城市脆弱性测度及动态演变特征对其转型发展具有重要意义。以西南地区典型资源型城市攀枝花市为研究对象,通过构建脆弱性测度指标体系,利用层次分析法确定指标权重,采用多因子综合评价法研究其脆弱性及动态。结果表明:(1)攀枝花市2006~2015年城市综合脆弱性总体呈下降趋势。其综合脆弱性指数从2006年的0.74下降到2015年的0.37,经历较高脆弱度、中脆弱度和较低脆弱度的演变;(2)该市近10 a来分系统中资源脆弱性年均值最大(0.57),其次为经济脆弱性(0.50),社会脆弱性(0.46)和生态环境脆弱性(0.43)相对较小。其中资源、生态环境和社会脆弱性均呈下降趋势,年均变化幅度分别为0.10、0.10、0.08,经济脆弱性呈振荡上升,年均变化幅度最大(0.13);(3)该市近10 a来经济系统对城市综合脆弱性贡献度上升明显(由2006年的15.53%上升到2015年的70.03%),同时社会脆弱性也较突出(2015年达20.16%)。未来攀枝花市在转型与城市脆弱性调控上应坚持以经济转型为核心,推进资源综合开发利用;进一步加强矿产资源地质勘探;推进区域统筹发展,减少社会脆弱性;提高工业固体废弃物综合利用,加强生态环境建设。
As a special type city,resource-based cities have four parts of its vulnerability,including resource vulnerability,eco-environmental vulnerability,economic vulnerability and social vulnerability. Discussing the vulnerability measures and dynamic evolution characteristics of the resource-based cities has great significance to its transformation development. This paper took Panzhihua-the typical resource-based cities in the southwest area,as the research object,focused on establish the vulnerability measure index system,utilized AHP（ Analytic Hierarchy Process） to determine the index weight and adopted multi-factor comprehensive evaluation method to study its vulnerability and dynamics. The results indicated that：（ 1） the trend of comprehensive vulnerability of Panzhihua in 2006-2015 was in decline. The index fell from 0. 74 in 2006 to 0. 37 in 2015,through the evolution of high vulnerability,middle vulnerability to low vulnerability.（ 2） In recent 10 years,the annual average of resource vulnerability（ 0. 57） was the maximum in Panzhihua,followed by economic vulnerability（ 0. 50）,while the social vulnerability（ 0. 46） and the eco-environmental vulnerability（ 0. 43） were relatively small. In the meantime,the resources vulnerability,eco-environmental vulnerability and the social vulnerability were declining,their annual variation was 0. 10,0. 10 and 0. 08. However,the economic vulnerability rose by oscillation,with the maximum annual variation（ 0. 13）.（ 3） In recent 10 years,the contribution to economic vulnerability of urban comprehensive vulnerability in Panzhihua rose significantly（ up from 15. 53% in 2006 to70. 03% in 2015）. At the same time,the contribution of the social vulnerability was also prominent（ 20. 16% in2015）. In the future,Panzhihua should adhere to the economic transition of the core in the transformation and city ＇s vulnerability regulation, promote the resources comprehensive exploitation and utilization; further strengthen geological prospecting min
