Derived Data

Against the background that urbanization has proceeded quickly in China over the last two decades, a limited number of empirical researches have been performed for analyzing the measurement and driving forces of urban sprawl at the national and regional level. The article aims at using remote sensing derived data and administrative data (for statistical purposes) to investigate the development status of urban sprawl together with its driving forces. Compared with existing studies, NPP/VIIRS data and LandScan data were used here to examine urban sprawl from two different perspectives: urban population sprawl and urban land sprawl. Furthermore, we used population density as a counter-indicator of urban sprawl, and the regression results also prove the superiority of the urban sprawl designed by us. The main results show that the intensity of urban population sprawl and urban land sprawl has been enhanced. However, the upside-down between the inflow of migrants and the supply of urban construction land among different regions aggravates the intensity of urban sprawl. According to the regression analyses, the driving mechanism of urban sprawl in the eastern region relying on land finance and financial development has lost momentum for the limitation of urban construction land supply. The continuous outflow of population and loosely land supply have accelerated the intensity of urban land sprawl in the central and western regions. The findings of the article may help people to realize that urban sprawl has become a staggering reality among Chinese cities; thereby urban planners as well as policymakers should make some actions to hinder the urban sprawl.

In this paper, taking the Zhengding new district of Shijiazhuang city as an example, we put forward to take advantages of analytic hierarchy process and rough set theory and combine them with fuzzy comprehensive evaluation method to do the quantitative analysis of suitability of the engineering geology conditions of urban construction land .It can make the evaluation more objective. This paper divides study area into the most suitable,suitable,less suitable and unsuitable,and provides a strong scientific basis for the design and planning.

The supply of construction land index is difficult in coal villages migration, especially the construction land index in urban and rural, lacking of construction land index becomes the bottleneck of village migration. In order to ruduce the pressure of the contradiction between supply and demand of land used for construction purposes. This paper combines with the actual situation of coal villages, taking Huainan as an example, starting from the connotation and significance of the policy of linking the increase in land used for urban construction with the decrease in land used for rural construction, based on the analysis of the current situation of the city construction land use, making predictions on the potentiality of village land readjustment in coal mining areas, the potentiality of the rural residential areas hook readjustment and the potentiality of linking the increase in land used for urban construction with the decrease in land used for rural construction, the results show that the overall hook potentiality is larger.
