| 摘要: | 我国城市化进程高速发展, 城市面临的风险趋向多元化、复杂化. 从城市韧性的角度出发, 构建了“规模-密度-形态-基础设施”四位一体城市韧性描述体系, 分析了浙江省2000年至2020年间城市韧性的时空变化, 并对城市发展方向提出了建议. 结果表明: 在研究期间, 浙江省城市韧性整体呈下降趋势, 其中城市规模韧性逐年下降, 存在着城市规模安全的隐患; 城市密度韧性呈下降趋势, 全省常年处于生态赤字风险之中; 城市形态韧性整体上有所下降, 但降幅较缓; 城市基础设施韧性呈螺旋上升趋势, 且各城市间差距逐渐缩小. 浙江省的城市韧性呈现出“西高东低”梯度化的空间格局, 相同韧性类型的城市也有集中分布的空间特征. 根据城市韧性描述体系的研究结果, 将浙江省各城市划分为高韧性城市、中韧性城市和低韧性城市三类, 并分别给出城市发展方向的建议. |
| Abstract: | Fast urbanization development puts it at risk which is characterized by diversity and complicatedness. From the perspective of urban resilience, in this paper the “size-density-morphology-infrastructure” is constructed for four dimensional integration city resilience description system with analysis on the urban spatial and temporal variations of resilience for zhejiang province between 2000 and 2020. Based on the study, suggestions on urban development directions are put forward. The results show that during the studied period, the urban resilience of Zhejiang Province presents an overall downward trend, in which the urban scale resilience decreases year by year, and there is a hidden danger of urban scale security. The resilience of urban density appears to be a downward trend, and the entire province is at the risk of ecological deficit. Urban type resilience has declined with slow pace in general. The resilience of urban infrastructure is spiraling upward, and the gap between cities is gradually narrowing. The spatial pattern of urban resilience in Zhejiang province is “high in the west and low in the east”. Cities with the same type of resilience also have the spatial characteristics of centralized distribution. From the results of the urban resilience description system, cities in Zhejiang province are divided into three types: high resilience city, medium resilience city and low resilience city. Suggestions for urban development directions are also given accordingly. |
