摘要
城市规模扩张背景下,多种复合风险频发,城市韧性提升应从动态角度关注生态、生产与生活用地间的匹配关系。基于土地利用分类栅格数据,采用“源—汇”景观距离指数方法分析上海市2000—2020年的三生空间韧性水平演变特征。结果显示,上海市生态—生活空间韧性与生产—生活空间韧性均存在明显等级分化特征,且后者呈明显下降趋势,该特征与资源禀赋与发展模式高度相关,建议采取生态融合式建设和新城人口导入政策,同时加强耕地保护以实现韧性发展。
The improvement of urban resilience should focus on the dynamic relationship between ecological,production and living spaces from a dynamic perspective.Based on land use classification grid data,the source-sink landscape distance index method was adopted to analyze the evolution characteristics of the resilience level of Shanghai’s production-living-ecological space from 2000 to 2020.The results showed that Shanghai’s ecological-living space and productive-living space resilience levels both displayed significant differentiation,with the latter exhibiting a clear downward trend.This feature is highly correlated with resource endowment and development mode.Therefore,it is recommended to adopt policies for ecological integration and new city population import while strengthening farmland protection to achieve resilient development.
