当前,我国城市用地规模扩展对城市绿地面积增加的支撑与制约作用十分明显,认识和把握两者之间的扩展关系,对于科学推进城市绿地建设和实现城市土地资源的合理配置具有现实意义。文章以我国1996~2013年的31个省级行政区建成区绿地面积、建成区面积的面板数据为基础,运用年均扩展面积、年均扩展速度、增速扩展系数刻画城市绿地与城市用地规模扩展的特征和规律,采用计量分析方法检验城市绿地与城市用地规模之间的长期均衡和作用程度。其分析结果可为我国相关研究提供数据参考。
At present, the scale of urban land expansion in our country is very obvious to support and restrict the increase of urban green area. It is of practical significance to understand and grasp the expanding relationship between urban green space and scientifically promote the rational allocation of urban land resources. Based on the panel data of green area and built-up area of 31 provincial-level administrative regions from 1996 to 2013 in our country, the paper uses the average annual expansion area, average annual expansion rate and growth expansion coefficient to characterize the expansion of urban green space and urban land use The characteristics and regularity of the urban green space and the scale of urban land use the quantitative analysis method to test the long-term equilibrium and the role degree. The results of the analysis can provide data reference for related research in our country.
