摘　　要：近20年来,我国城市绿地水平普遍提高,但空间差异明显,基于"省域尺度"研究城市绿地水平的时空演变特征及区域差异构成,可为城市绿地的协调发展提供理论依据。以江苏省县级及以上的城市为研究对象,选取城市绿地面积、建成区绿地率、人均公园绿地面积三个指标,采用扩展速度、扩展系数分析城市绿地水平的时空演变,运用锡尔系数进行江苏省差异分解研究。实证表明:江苏省城市绿地水平处于快速提升阶段,城市绿地面积的均衡程度也明显提高;江苏省三大地带间差异明显缩小,城市绿地扩展速度从高到低依次为苏北、苏中和苏南;江苏城市绿地水平总体差异主要是由地带内市际差异引起,但地带间差异的贡献度在逐渐提高。In the last 20 years, the level of urban green space in China has generally improved. However, the spatial difference is obvious. We research the temporal and spatial evolution characteristic and regional difference of urban green space based on the ＂province scale＂ , which can provide the theory foundation for urban green coordinated development. We take the cities of Jiangsu as the objects, choose three indicators of green area of built district, green space rate of built district and public recreational green space per capita, use the method of extension rate and expansion coefficient to analyze the spatio-temporal evolution of urban green, and we also study the overall difference by Theil indices. The result shows that the level and equ{librium of urban green space had been ascending rapidly. The difference between three zones had been significantly reduced. Urban green space expansion rate from high to low in turn was Subei, Suzhong and Sunan. The overall difference of urban green space in Jiangsu was caused by the difference among cities, however, the contribution of the difference among zones had been gradually improving.
