韧性城市视角下土地生态安全评价

Land Ecological Security Evaluation from the Perspective of Resilient City

基于韧性城市理念构建评价体系,采用熵权法、障碍度模型等方法,探究山东半岛城市群土地生态安全演变特征和障碍因子。结果表明:山东半岛城市群土地生态安全等级稳步提升,呈现“核心-边缘”分布格局,济南、青岛“双核心”特征明显;土地经济、社会生态安全增速快,土地自然生态安全增速慢;经济稳定性、经济恢复性、社会稳定性、社会脆弱性、社会恢复性障碍度呈下降态势;地均社会消费品零售总额、地均财政收入等为主要障碍因子。

An evaluation system was constructed based on the concept of resilient city,and the e-volution characteristics and obstacle factors of land ecological security in Shandong Province were explored by means of entropy weight method and obstacle degree model.The results show that the level of land ecological security in Shandong Province is increased steadily,presenting a"core-edge"distribution pattern,and the characteristics of"dual core"are obvious in Jinan and Qingd-ao.The growth rate of land economic and social ecological security is fast,while the growth rate of land natural ecological security is slow.The degree of economic stability,economic recovery,social stability,social vulnerability and social recovery obstacle decrease.The main obstacle fac-tors are the total retail sales of consumer goods and the fiscal revenue of local average.
