【摘要】：近年来,我国城市绿地水平普遍提高,但建成区绿地率与人均公园绿地面积失调较为严重,且城市间存在明显的差异性。研究以我国地级及以上城市为研究单元,采用1990~2011年各市建成区绿地率与人均公园绿地面积的截面数据,通过模型测度各城市建成区绿地率与人均公园绿地面积的离差系数,以揭示我国城市建成区绿地率与人均公园绿地面积失调的特征及差异性,结果表明:全国整体失调较为严重,并且失调等级呈增强的态势;四大地区失调性由东北向东、西部再向中部逐步增强;巨型城市协调性最好,其他几类城市总体发展比较均衡,但其内部差异性也比较明显,规模小的城市高度失调以上等级所占比例大;从城市类别上看,行政级别越低的城市,失调等级越高。
[Abstract]:In recent years, the level of urban green space in China has been improved generally, but the proportion of green space in the constructed areas and the per capita area of park green space are more serious, and there are obvious differences between cities. Taking cities at or above the prefectural level as the research unit, using the section data of green space rate and per capita park green space area of each city from 1990 to 2011, the deviation coefficient between the green space rate and the per capita park green space area of each city is measured by the model. In order to reveal the characteristics and differences between urban green space rate and per capita park area imbalance in China, the results show that the overall imbalance is serious in China, and the imbalance grade is increasing; The maladjustment of the four major regions is gradually strengthened from northeast to east and from west to central; The coordination of megacities is the best, and the overall development of several other cities is more balanced, but the internal differences are also obvious. In terms of city category, the lower the administrative level, the higher the level of maladjustment.
