我国城市绿地建设水平的区域差异研究

我国城市绿地建设存在一定的地区差异，这种差异直接反映在人均公共绿地面积、建成区绿地率和建成区绿化覆盖率这三项绿地指标上。以省为单位，依据这三项绿地指标进行聚类分析，可将全国31个省、自治区、直辖市分为城市绿化先进区、达标区、未达标区和缺乏区四类。我国城市绿地建设水平自东向西呈阶梯状由高到低变化，主要是受地形地貌、城市建设资金投入、发展理念等因素的影响。

Regional Difference in Urban Green Space in China

There is difference in urban green space level of different regions in China, which is reflected in number and percentage of green space, as well as green coverage per capita. This paper analyzes these three indexes of each province and divides them into four levels in terms of green space construction: good, sufficient, insufficient, and bad. The green space level degrades from east to west due to difference in geography, investment, development concept, etc.
