中文摘要:
      桂林是典型的旅游城市,对其脆弱性成因及动态演变进行分析与评价,能够为降低城市脆弱性提供科学依据。以桂林市为研究对象,从生态环境、经济、社会和资源四个系统构建评价指标体系,运用AHP确定评价指标的权重,用综合指数评价法计算城市脆弱性指数。通过分析桂林市综合脆弱性的动态演变过程,可以发现:(1)2009—2018年,生态环境脆弱性波动较大,资源脆弱性、经济脆弱性和社会脆弱性逐年持续走低;(2)桂林城市综合脆弱性可分为逐年下降、缓和上升和波动下降三个阶段,整体上看综合脆弱性指数降低了70%,表明桂林市对外界抗干扰能力增强,城市发展质量有所提高;(3)城市综合脆弱性与生态环境相关性较大,桂林市脆弱性由经济和社会主导转为生态环境主导。城市脆弱性是城市发展中形成的“慢性病”,需要及时调理,否则会导致城市系统的崩溃。建立城市脆弱性评价体系,有助于诊断城市问题,可为降低城市脆弱性指引方向。
英文摘要:
      Guilin is a typical tourist city.The analysis and evaluation of the causes of its vulnerability and its dynamic evolution can provide a scientific basis for reducing urban vulnerability.Taken Guilin city as the research object,this paper constructed the evaluation index system from the four systems of ecological environment,economy,society and resources,used AHP to determine the weight of the evaluation index,and calculated the urban vulnerability index by means of Comprehensive index evaluation method.Through the analysis of the dynamic evolution process of comprehensive vulnerability in Guilin,it can be found that:from 2009 to 2018,the ecological environment vulnerability fluctuated greatly,and the vulnerability of resources,economy and society continued to decline year by year;the comprehensive vulnerability of Guilin city can be divided into three stages:year on year decline,moderate rise and wavelike decrease.On the whole,the comprehensive vulnerability index decreased by 70%,indicating that the anti interference ability of Guilin to the outside world was enhanced,and the quality of urban development was improved.There is a great correlation between the urban comprehensive vulnerability and the ecological environment.The vulnerability of Guilin city has changed from the economic and social leading to the ecological environment leading.Urban vulnerability is a “chronic disease” formed in urban development,which needs timely adjustment,otherwise it will lead to the collapse of urban system.The establishment of urban vulnerability assessment system is helpful to diagnose urban problems and guide the way to reduce urban vulnerability.
