【摘要】：随着我国城市绿地建设的不断发展,城市绿地建设水平的区域差异问题日益凸显。选取建成区绿地率的指标,运用锡尔系数对我国四大地区及其所属的省、市、自治区进行城市绿地建设水平的总体差异和构成分解,实证分析表明:我国城市绿地具有非均衡空间分布特征,全国总体区域相对差异明显缩小;城市绿地建设水平总体差异主要是由地区内差异引起,地区间差异对总体差异的贡献度在逐渐提高;在四大地区内省际差异中,东部省际差异对全国总体差异影响最大,西部影响较大,中部影响较小,东北影响最小;东部省际差异呈大幅下降趋势,西部省际差异一直保持在较高水平,中部、东北省际城市绿地建设水平发展均衡,且变动幅度也小,均呈现降低的趋势。分析认为上述区域差异及演变是由建成区规模变化、经济发展水平、人口、政策、自然地理和资源条件等因素综合作用造成的。
[Abstract]:With the continuous development of urban green space construction in China, the regional differences in the level of urban green space construction are increasingly prominent. Select the green space rate index of the built areas, and apply the Sier coefficient to the four regions of our country and their provinces and cities. The overall difference and composition decomposition of urban green space construction level in the autonomous region are analyzed. The empirical analysis shows that the urban green space in our country has the characteristics of disequilibrium spatial distribution, and the relative difference between the whole country and the whole area is obviously reduced. The overall difference of urban green space construction level is mainly caused by the difference within the region, and the contribution degree of the regional difference to the overall difference is gradually increasing. Among the inter-provincial differences in the four major regions, the eastern inter-provincial differences have the greatest impact on the overall national differences, the western region has a greater impact, the central one has a small impact, and the Northeast has the least impact. The inter-provincial differences in the eastern region show a significant downward trend, the inter-provincial differences in the west have been maintained at a higher level, the central and northeast provinces of urban green space construction level balanced development, and the range of change is small. It is concluded that the above regional differences and evolution are caused by the comprehensive effects of the scale change, the level of economic development, population, policy, natural geography and resource conditions.

【正文快照】： 城市绿地建设水平区域差异是指一定时期内不同区域之间城市绿地建设水平的非均衡化现象,是反映区域城市绿地发展水平、质量的重要特征。20世纪90年代以来,我国城市绿地建设进入快速发展阶段[1-5]。1990—2011年,我国建成区绿地率从9.98%提升到35.27%,人均公园(公共)绿地面积从
