Spatial heterogeneity analysis and driving forces exploring of built-up land development intensity in Chinese prefecture-level cities and implications for future Urban Land intensive use

The evolution of urban form is a slow and complex process driven by various factors which influence its pattern of occurrence (time, shape and directions) over time. Given the ever-increasing demand for urban expansion, and its negative effects on travel efficiency and environmental quality, it is imperative to understand the driving forces behind this complex process. This study investigates the role played by transport developments in the expansion of Perth’s urban footprint. Since transport developments are influenced by prevailing economic developments and planning regulations, our analysis starts by deconstructing a timeline of milestones under these three themes, from an urban land development perspective. An overview of the eras of transport evolution is provided, and we discuss the pattern of urban form changes as they relate to these transport advancements. The paper ends by mapping and quantifying changes in Perth’s urban land over the past five decades. The results show that transport had a strong influence on the pattern of urban expansion for a long time, but that trend has now been reversed. Rail constructions have been playing catch-up to residential expansion since the late twentieth century. Meanwhile, the rate of urban expansion has gone down in the twenty-first century, as the city goes for compact growth.

Spatial Analysis Method

Worldwide urban spatial expansion has become a hot topic in recent decades. To develop effective urban growth containment strategies, it is important to understand the spatial patterns and driving forces of urban sprawl. By employing a spatial analysis method and land use survey data for the years 1996–2010, this study explores the effects of hierarchical administrative centers on the intensity and direction of urban land expansion in a Beijing municipality. The results are as follows: (1) land development intensity and expansion speeds are both affected significantly by the municipal and district and county centers where the governments hold a lot of administrative, public, and economic resources. (2) The distances to the administrative centers are determinant factors for the direction of urban land expansion. Except for several subregions adjacent to the municipal center, the closer the area is to an administrative center, the more likely it is that the expansion direction points toward the center. (3) The spatial patterns of urban land development are shaped jointly by governments at different levels, and transportation lines also play a role in remote areas. These findings are expected to have consulting value for future policymaking on urban land use and management in mega-cities, especially those with strong local government powers in other transition economies and developing countries.

Bp Neural Network Model

Using BP neural network model to analyze the urban land development status of Zhengzhou City from 2013 to 2017, the evaluation grades are divided into over-utilization, intensive use, moderate utilization and extensive utilization, and from the land input intensity, land use intensity and a total of nine indicators were selected for evaluation in three aspects of land output benefits. The results show that the urban land intensive degree of Zhengzhou City during the five years from 2013 to 2017 is 0.3039, 0.5118, 0.6189, 0.6914, 0.8509, and the intensive degree is gradually increased every year. The degree of intensive use is gradually increased every year, the evaluation level has risen from extensive use to intensive use, and the intensity of land intensive use has continued to increase.
