珠三角城市群人居环境高质量发展时空演化特征及影响因素

综合运用熵权法、协调度研究了2010—2019年珠三角城市群人居环境高质量发展时空演化特征,并采用障碍度分析了该城市群影响人居环境高质量发展的障碍因子。结果表明:①珠三角城市群人居环境高质量水平呈上升的态势,空间分布呈“屋脊”式格局,区域差异明显。②在人居环境高质量五大准则层中,除生态环境外,其他四大准则层均表现为波动上升态势,协调度呈现高质量低协调和低质量高协调两种差异。③公共基础服务、社会经济和居住环境对珠三角城市群人居环境高质量发展障碍度较大。

Spatial-temporal Evolution and Influencing Factors of High-quality Development of Human Settlements in the Pearl River Delta Urban Agglomeration

Comprehensive used of entropy method and coordination degree,this paper analyzed the spatial-temporal evolution characteris tics of the high-quality development of the human settlement environment in the Pearl River Delta Urban Agglomeration from 2010 to 2019,and used the obstacle degree to analyze the obstacle factors that affect the high-quality development of the human settlement environment.The results showed that:①The high-quality level of human settlements in the Pearl River Delta Uban Agglomeration was on the rise;the spatial distribution presented a“roof-ridge”pattern,with obvious regional differences.②Among the five criteria levels for high-quality human set tlements,the other four criteria levels except for the ecological environment all showed a trend of rising volatility,and the degree of coordination presented two differences between high-quality,low-coordination and low-quality,high-coordination.③Public basic services,social econ omy,and the living environment had greater obstacles to the high-quality development of the human settlement environment.
