| 摘 要： | 运用G IS技术,以1 km×1 km格网为基本评价单元,计算了陕北的城镇化水平指数和生态环境质量指数,并系统地分析了两者的空间协调程度。结果表明:(1)陕北城镇化水平和生态环境质量整体偏低。在空间分布上,城镇化水平呈北高南低、东高西低趋势,而生态环境质量则南部优于北部、东西部优于中部。(2)陕北城镇化水平与生态环境质量之间存在明显的空间差异,根据两者之间的空间协调程度可将陕北划分为过快高胁迫、较快强胁迫、基本协调、较缓弱胁迫和缓慢低胁迫5种类型区。

| Abstract: | The fragile eco-environment constrains the urbanization in northern Shaanxi Province,while highly urbanization has a certain role of coercion on eco-environment.In this paper,the urbanization level and the eco-environment quality were evaluated respectively in northern Shaanxi by using the ArcGIS technology.At the same time also analyzed the spatial coordination degree between urbanization and eco-environment quality.The results showed that: the level of urbanization and the quality of eco-environment in no... |
