Abstract:Regarding 17 cities as the research units,the paper explored internal coordination and its spatiotemporal characteristics of intensive urban land use in He'nan Province.The main conclusions are as follows.Firstly,measuring on the internal coordination of intensive urban land use is not only feasible,but also new 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 between the intensive levels of urban land use and the 4 subsystems(land input level,land productivity,land use degree and land eco-environmental quality)showed a gradually rising trend,and generally the stage changed from an antagonistic stage to coordination stage passing by running-in stage.Fourthly,the whole intensive level of urban land use in He'nan Province gradually increased.However,the intensive level differences 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.
