河南省城市土地集约利用内部协调性的时空演变

Spatiotemporal Characteristics of Internal Coordination of Intensive Urban Land Use in He′nan Province

以河南省17个省辖市为研究单元,探索了不同研究年份城市土地集约利用的内部协调性及其演变格局。研究表明:(1)对城市土地集约利用的内部协调性测度是可行的,也是必要的。(2)河南省城市土地集约利用的内部整体协调性呈现明显的上升态势,且其水平高低与城市所在区域的资源禀赋、工业基础和城市基础设施建设等因素密切相关。(3)城市土地集约利用水平与4个子系统(土地投入水平、土地产出水平、土地利用程度和土地生态环境质量)之间的内部局部协调性呈逐步上升的态势,且从总体上由拮抗阶段,经磨合阶段,向协调阶段推进。(4)河南省城市土地集约利用水平逐步提高,但同一研究年份不同城市之间的土地集约利用水平差异却逐渐增大。(5)在不同研究年份,4个子系统对城市土地集约利用水平的影响力大小是不同的。

Regarding 17 cities as the research units, the paper explored internal coordination and its spatio temporal characteristics of intensive urban land use in Helnan Province. The main conclusions are as follows. Firstly, measuring on the internal coordination of intensive urban land use is not only feasible, but also nec essary. Secondly, the whole internal coordination of intensive urban land use in He＇nan Province showed an obviously rising trend, and its level was closely related to such factors as the region＇s resources endowment, industrial foundation and urban infrastructure construction. Thirdly, the partial internal coordinations be tween the intensive levels of urban land use and the 4 subsystems（land input level, land productivity, land use degree and land ecoenvironmental quality） showed a gradually rising trend, and generally the stage changed from an antagonistic stage to coordination stage passing by runningin stage. Fourthly, the whole intensive level of urban land use in Hernan Province gradually increased. However, the intensive level differ ences of urban land use between different cities were gradually increasing in the same research years. Finally, each influence of 4 subsystems on the intensive levels of urban land use was different in the different research years.
