Assessing construction land potential and its spatial pattern in China

et al. 2018

Abstract:Land use change is extremely sensitive to natural factors and human influence in active debris flow. It is therefore necessary to determine the factors that influence land use change. This paper took Wudu District, Gansu Province, China as a study area, and a systemic analysis of the transformational extent and rate of debris flow waste-shoal land ( The latter is more than 60 times the former. This increase was brought about by natural disasters (debris flow, earthquakes, and landslides) and anthropogenic factors (national policies or strategies), which acted as driving forces in debris flow area. The former determines the initial use type of the DFWSL while the latter only affects the direction of land use and transformation.

“…We examined related research findings [35,[37][38][39][40][41][42][43] and tailored them to Changzhou's circumstances. Then, an index system that assesses the quality of national territory use was created within the context of harmoniously developing production-living-ecology spaces.…”

A Quality Assessment of National Territory Use at the City Level: A Planning Review Perspective

Gong

et al. 2016

With increasing urbanization, the populations in China's cities are growing, and the cities themselves are gradually expanding. Competition for access to the national territory's resources is also growing. Thus, the quality of national territory use is worsening. Quality assessments on national territory use can provide a basis for solving this issue. By combining the implications of new urbanization in China, we established an assessment index system relating to the quality of national territory use, from the perspective of harmoniously developing spaces for production, living and ecology. A subjective and objective integrated weighting method was developed based on principal component analysis and planning review. Then, a comprehensive discriminative model was established to assess the quality of national territory use. The evaluation results showed that harmonious development of spaces for production, living and ecology did not occur in either the ecology-oriented or production-oriented regions. The integrated quality of national territory use in the production-oriented region had a significant advantage over that of the ecology-oriented region. The integrated quality of national territory use was highest in Changzhou's city center and vicinity. The results can support the implementation of China's new urbanization strategy and provide evidence to improve the criteria for the intensive use of national territorial resources.

“…The planning of MFOZs is based on a comprehensive evaluation of the suitability of territorial functions using an index system that consists of six indices related to environmental resources (i.e., available land resources, available water resources, environmental capacity, ecological importance, and natural disaster potential), one index of population agglomeration, one index of economic development, and two indices related to development potential (i.e., transport dominance and strategic selection) [31][32][33]; all of the indices are quantitative except for strategic selection. Therefore, evaluations of potential MFOZs can not only take into account the economic and social development of an area but can also consider the natural environment and limits to ensure sustainable development.…”

“…The connectivity index for roads, the connectivity index for railways and the connectivity for aviation (in Level IV) represent urban accessibility in the provincial capitals. Hypsography refers to the relative elevations of different land areas, including elevation and slope (in Level IV), which are taken as the main variables for selecting available land resources in the evaluation of MFOZs [33]. Elevation and slope are used to represent the convenience of industrialization and urbanization.…”

Measuring and Analysis of Urban Competitiveness of Chinese Provincial Capitals in 2010 under the Constraints of Major Function-Oriented Zoning Utilizing Spatial Analysis

Ren

et al. 2014

Urban competitiveness aids local development by encouraging the exploitation of opportunities for economic development and by enhancing overall performance. Previous studies have evaluated urban competitiveness primarily from an economic perspective and few studies have considered locational conditions as factors that might influence local industrialization and urbanization. In response to the publishing of a national plan for the development of major function-oriented zones (MFOZs) in 2010, the present essay employs MFOZs as constraints to enable a balanced and comprehensive study of urban competitiveness that includes four dimensions of competitiveness: Economic, social-cultural, environmental, and locational (accessibility and hypsography). A four-level hierarchical indicator system and an entropy weighting method were used to assess the urban competitiveness of 31 Chinese provincial capitals based on a spatial analysis of data acquired in 2010 using Geographic Information System technology. The results reveal the overall ranking of provincial capitals in terms of urban competitiveness and their performances with respect to the four dimensions of competitiveness. Unlike OPEN ACCESSSustainability 2014, 6 3375 previous studies, this analysis was performed by overlaying the strategy of the national MFOZ with the urban competitiveness rankings. The development orientation of each provincial city is discussed according to its characteristics of urban competitiveness under the conditions of a MFOZ.
