【摘要】：在对国内外城市脆弱性及其评价体系的研究脉络进行梳理的基础上,针对已有研究的不足之处,提出城市脆弱性综合评价模型,将其设定为四个目标层,即资源脆弱性、生态脆弱性、经济脆弱性、社会脆弱性,各目标层的脆弱性则设定为敏感性、适应性、应对力三个因子的综合函数,使评价模型能更全面地评价城市的脆弱性,同时,又能反映出各城市脆弱性的主要症结,为风险控制提供思路。通过对河南省18个省辖市脆弱度进行测量,发现总体脆弱性呈降低趋势,与区位密切相关,同时也找出了各城市的脆弱性风险主导因子,据此,提出河南不同省辖市降低城市脆弱性的具体措施,包括建设紧凑城市、生态城市、双创城市、海绵城市,慎建城市新区等建议。
[Abstract]:On the basis of combing the research context of urban vulnerability and its evaluation system at home and abroad, a comprehensive evaluation model of urban vulnerability is put forward, which is defined as four target layers, that is, resource vulnerability.Ecological vulnerability, economic vulnerability, social vulnerability, vulnerability of each target layer are set as three comprehensive functions of sensitivity, adaptability and coping power, so that the evaluation model can evaluate the vulnerability of cities more comprehensively, at the same time,It can also reflect the main crux of the vulnerability of cities and provide ideas for risk control.By measuring the vulnerability of 18 provinces and municipalities in Henan Province, it is found that the overall vulnerability shows a decreasing trend, which is closely related to the location. At the same time, the leading factors of vulnerability risk in each city are also found.The specific measures to reduce the vulnerability of cities in different provinces and municipalities of Henan Province are put forward, including the construction of compact cities, ecological cities, double creation cities, sponge cities, careful construction of new urban areas, and so on.
