Abstract:
Taking 2014 as the evaluation point,the construction land within the scale of urban land use in Nanjing center as the object of study,according to the principles and methods of functional area delineation,it was divided into 641 functional areas,including residential,commercial,industry,education,administrative and other functions. It took the method of multi factor evaluation to quantitatively evaluate the intensive utilization of various functional areas,and took the method of ESDA to analyze the spatial autocorrelation of land use intensity to reveal distribution law. The results showed that:the intensive use is the main construction in Nanjing central urban area,followed by moderate utilization; the residential functional area had the highest land use intensity,the industry functional area had the lowest land use intensity; the extent of land intensive utilization is higher in the center than Xianlin,Dongshan and Jiangbei vice city,showed a distribution pattern of decreasing from the center to the periphery; the land use intensity of various functional areas have significant spatial positive correlation and spatial agglomeration,among which the residential function was the best,and the educational function was inferior; the city center with high value of intensive degree should adopt structural adjustment potential tapping method to optimize land structure through urban renewal and three-dimensional development,the city edge with low value of intensive degree should take connotation management potential tapping method to increase the intensity of land use through increasing investment and planning. This paper is expected to provide basis for improving land benefit of urban construction land in Nanjing.
