中国城市绿地空间分布特征及其影响因素研究

Research on Spatial Distribution Characteristics and its Influencing Factors of the City Green Space in China

利用2007年中国城市社会经济统计资料对中国241个地级及以上城市的建成区绿地面积进行分析。结果显示:①建成区绿化覆盖率分布走向由东南至西北逐渐降低,该分布情况与我国的城市化程度、经济发展及人口密度分布方向基本一致。②建成区绿化覆盖面积与建成区土地面积、地区生产总值和人口数量呈正相关,以建成区绿化覆盖面积受建成区土地面积影响最大,地区总产值次之。

It is analyzed that based on the Chinese urban social economic statistics collected in 2007,the research on green coverage rates shows three conclusions in 241 prefecture-level cities.First,the green coverage rate of the built-up areas is declining from the southeast to the northwest,and the trend coincides with the directional distributions of the urbanization degree,the economic development and the population density and spatial distribution;Second,there is a positive correlation with the green coverage rate and the built-up land area or the GDP,and the green coverage rate is mostly affected by the built-up land area,and then followed by the GDP.
