摘要
【目的】人居环境建设对黄河流域城市的高质量发展具有重要意义。本文旨在立足于韧性与人居环境理论,厘清黄河流域不同类型资源型城市的人居环境韧性水平与障碍度,丰富人居环境韧性相关研究,深化对人居环境这一复杂体系的理解。【方法】本文基于自然、人类、居住、社会、支撑5个子系统,构建黄河流域资源型城市人居环境韧性综合评价指标体系,运用HP滤波分析、三维核密度、热点分析、障碍度模型等方法,分析其2007—2021年的时空演化特征,并对影响人居环境韧性的障碍因子进行科学诊断。【结果】(1)从时序演化特征看,黄河流域资源型城市人居环境韧性整体处于波动上升态势,其演化周期经历了“低位停滞—渐进提升—波动骤升”3个阶段;不同类型资源型城市人居环境韧性日益提升的趋势均比较明显,其中成熟型、再生型城市韧性水平的提升幅度明显高于衰退型、成长型城市。(2)从空间演化特征看,城市人居环境韧性水平在空间上呈现“外围高于中心、下游高于上游”的格局特征,且空间集聚变化较为稳定,形成黄河流域外围热点区域空间集聚的特征。(3)从准则层看,各子系统障碍度变化相对稳定,整体大小表现为支撑韧性>自然韧性>社会韧性>人类韧性>居住韧性,具体到因子层面,单位面积水资源量、研发投入占GDP比重、污染物综合指数等为主要障碍因子,且不同类型资源型城市人居环境韧性的主要障碍因子存在空间异质性。【结论】黄河流域资源型城市的人居环境韧性水平总体处于上升趋势,且存在显著的空间区域差异。未来亟需从水资源、区域创新以及环境污染等方面优化人居环境韧性。
[Objective] The construction of the human settlement environment holds great significance for the high-quality development of cities in the Yellow River Basin.The human settlements of different types of resource-based cities are heterogeneous.Exploring the change of the human settlement resilience level and obstacle degree of these cities is conducive to providing targeted policies for the construction of human settlements in different types of cities.[Methods] This study developed a comprehensive evaluation indicator system of human settlement resilience of resourcebased cities in the Yellow River Basin based on the human-natural-living space-social-support subsystems,and used HP filter analysis,three-dimensional kernel density estimation,hotspot analysis,and the obstacle degree model to examine the spatiotemporal change characteristics of the human settlements from 2007 to 2021.A scientific diagnosis was conducted to identify the obstructive factors that influenced the resilience of human settlements.[Results](1) From the perspective of temporal evolution characteristics,the human settlement resilience of resource-based cities in the Yellow River Basin showed a fluctuating and increasing trend,and had gone through three stages of low-level stagnation,gradual improvement,and sudden increase with fluctuation.The rising resilience of human settlements in different types of resource-based cities was obvious,among which the resilience of mature-type and regen-eration-type cities was significantly higher than that of growth-type and decline-type cities.The growth-type,mature-type,and regeneration-type cities all showed an agglomeration of high resilience cities,while the decline-type cities with high resilience level tended to be dispersed.(2) From the perspective of spatial evolution,the resilience level of urban human settlements presents a spatial pattern of “periphery is higher than center,downstream is higher than upstream.The spatial agglomeration changes are relatively stable,forming the characteristics of s
