我国不同行政级别城市的建成区绿地率差异实证分析

Empirical analysis on differences of green space rate of built districts in cities of different administrative levels of China

我国采用行政区划对城市进行分级管理,不同行政级别的城市绿地建设水平呈现差异,以建成区绿地率为研究指标将不同行政级别城市绿地建设水平差异定量化,对统筹全国城市绿地建设具有一定意义。以我国655个城市为样本,运用锡尔系数、变异系数等方法,呈现2012年全国基于不同行政级别的城市绿地建设水平差异构成,以及各行政级别组内部城市之间的绿地建设水平差异表现。

The cities in our countries are managed at different levels according to the administrative divisions,and the green space construction in cities of different administrative levels is different from each other. The dif-ferences of urban green space construction between different administrative levels of cities are quantified by using the green rate as the study index, which is of important significance to the construction of the national urban green space. With the 655 cities in China as a sample, methods such as the Theil coefficient, the coefficient of variation and so on are used to present how the different administrative levels of cities contribute to the overall differences of the urban green space construction in our country and the differences of the city green space construction between cities in different administrative levels in 2012.
