Urban Land Use
Handbook of Regional and Urban Economics, 2015Co-Authors: Gilles Duranton, Diego PugaAbstract:We provide an integrated treatment of the theoretical literature on Urban Land Use inspired by the monocentric model, including extensions that deal with multiple endogenous business centres, various dimensions of heterogeneity, and durable housing. After presenting the theory and distilling its key empirical implications, we critically review the empirical literature on differences in prices and development across Urban locations, patterns of location choices of heterogeneous hoUseholds in cities, sprawl and residential decentralization, and employment decentralization.

Research Progress and Prospects of the Researches on Urban Land Use Structure in China
Progress in geography, 2010Co-Authors: Wen FengAbstract:Urban Land Use structure is always one of research cores both in Urban plan and Urban geography. Reasonable Land Use structure has been one of the ways to ptomote Urban function and Land Use benefits. This paper reviews the research results of Urban Land Use structure according to Urban Land Use evolution feature, driving mechanism of Urban Land Use evolution, Urban Land Use structure optimization and Urban Land Use structure dynamic simulation. The conclusions show the present reasearch has its own limits in methods and contents. In the future, following works should be conducted. (1) From the view of rational arrangement of Urban functional structure, the relations between Urban functional structure and Urban Land Use structure should be studied and the general rule of Urban Land Use structure evolution in different industrial phases should be explored; (2) Static models should be changed to dynamic-quantitative models, and a supporting system for decision-making should be established; (3) A theoretical framework for regulating Urban Land Use types and Land Use structures should be established to provide a theoretical support for Urban planning and Land Use spatial distribution optimization.

Spatial Patterns and Dynamic Mechanisms of Urban Land Use Growth
Progress in geography, 2002Co-Authors: Liu ShengAbstract:Through carrying out a systematical review on the research progress of various Western academic schools on spatial patterns and dynamic mechanisms of Urban Land Use growth, this paper highlights that its focus has shifted from summarizing spatial evolutionary models to exploring dynamic mechanisms during the decision making process of Land development, from free Land market to smart growth management. Historical experiences at home and aboard demonstrate that, while the monopoly administrative allocation system would force Urban Land Use development to become an affiliated part of administrative powers and result in inefficiency and inequality, the free market mechanism would probably push Urban Land development to become an growth machine solely controlled by the motivation of profit making and deliberately destroy un renewable resources and amenable ecological environment. Therefore, in order to realize sustainable Urban development and coordinate the conflicts among Urban development, conservation of cultivated Land, and construction of ecological environment, China should, on one side, continue to accelerate its reform on Urban Land Use system to significantly increase the importance of the market mechanism on Urban Land development, and establish an equal and efficient supervising mechanism on the operation of Urban Land market, on the other side, strengthen the macro management function of the Governmental agencies and rationally control Urban Land Use growth motivated by the market mechanism through various growth management policies.

A critical review on the progress of Urban Land Use theories in the West
Geographical Research, 2001Co-Authors: Liu ShengAbstract:This paper carries out a systematical literature survey and critical review on the research progress of Urban Land Use theories in the West, which are classified into historical morphological, locational economics, social behavior, and political economics by their research approaches. The historical morphological approach is good at exploring the spatial differentiation laws and the evolutionary models of Urban Land Use, but its simple circular models are inconsistent with actual situation. The locational economics approach provides strong quantified economic explanation on the spatial structure of Urban Land Use through deep decomposing the price components of Urban Land, but it pays more attention to “why” than to “what”. The behavior analysis approach becomes more comprehensive and practical becaUse it additionally takes social driving forces into account, but it is based on the two concepts of “uncertainty” and “stochastity” of individual decision makers of Land Use, thus its theoretical explanation power is rather limited. The political economics approach focUses on the impact of the social production system and “power” on the process of Urban Land development, and greatly extends and enhances our understanding on inner dynamic mechanics of Urban Land development. Finally, this paper emphasizes that China should adopt and strengthen the application of locational economics and political economics approaches in its researches on Urban Land Use in the future.

A GIS based Model of Urban Land Use Growth in Beijing
2000Co-Authors: Liu ShengAbstract:Based on the Land Use maps of Beijing in 1982, 1992 and 1997, its spatial and temporal process of Urban Land Use growth was analyzed through spatial clustering and historical morphological approaches. The growth intensity index (GII), was employed instead of growth speed to describe the spatial differentiation of Urban Land Use growth. Assisted by spatial analysis techniques of GIS, the average GIIs per year (AGIIPY) of 155 communes or towns during 1982~1992 and 1992~1997 were calculated and then classified through the Natural Breaks method, and the spatial differentiation maps of Urban Land Use growth in Beijing during 1982~1992 and 1992~1997 were made. This paper found: (1) Industrial Land is the most important element of Urban Land Use growth in Beijing, and its contribution rate is on the increase, which is different from the general Western Urban growth model driven by residential expansion. Since 1982, the industrial Land had been keeping expanded at the average rate of 24~25 km 2 per year. It is extraordinary high especially during the 1992~1997 period, while that of residential Land and Urban Land Use dropped by 59% and 24%, to 3 4 km 2 per year and 29 8 km 2 per year respectively. Thus, the contribution rate of industrial Land to Urban Land Use growth increased from 64 91% in 1982~1992 to 80 67% in 1992~1997. (2) The spatial pattern of Urban Land Use growth in Beijing was in distinct concentric sprawl. With the growth centers' gradual shift from the inner to outside, the new added Urban Land Use were increased in distinct concentric zones and continually encroached upon the green spaces among the central mass and those “dispersed constellations”. The total area of green spaces for isolating built up areas in General Plan of Beijing, was 314 km 2 in 1958, reduced to 260 km 2 in 1983 and 160 km 2 in 1993. The concentric sprawl pattern seriously destroyed the spatial structure of “dispersed constellations” designed by the General Plan of Beijing, and also badly worsened the regional ecological environment. (3) The growth axes of Urban Land Use in the southern and eastern part of Beijing had stepped into their decline period. The southern and eastern part of Beijing is located in the North China Plain and have advantages in Urban development space, economic and transport communication, etc., so that they are determined as the main Urban development areas and direction by the latest General Plan (1991~2010). But this paper found, the two major growth axes of Urban Land Use along the Beijing Tian Jin and Beijing Shen Zhen highways in the southern and eastern part of Beijing, had stepped into their decline period during 1992~1997. Their AGIIPY decreased from 1 63 and 1 58 during 1982~1992 to 0 86 and 0 67 respectively, and the spatial growth pattern have also switched from vigorous axial expansion to fill in among axes.

Social Sensing for Urban Land Use Identification
ISPRS International Journal of Geo-Information, 2020Co-Authors: Adindha Surya Anugraha, Hone Jay Chu, Muhammad Zeeshan AliAbstract:The utilization of Urban Land Use maps can reveal the patterns of human behavior through the extraction of the socioeconomic and demographic characteristics of Urban Land Use. Remote sensing that holds detailed and abundant information on spectral, textual, contextual, and spatial configurations is crucial to obtaining Land Use maps that reveal changes in the Urban environment. However, social sensing is essential to revealing the socioeconomic and demographic characteristics of Urban Land Use. This data mining approach is related to data cleaning/outlier removal and machine learning, and is Used to achieve Land Use classification from remote and social sensing data. In bicycle and taxi density maps, the daytime destination and nighttime origin density reflects work-related Land Uses, including commercial and industrial areas. By contrast, the nighttime destination and daytime origin density pattern captures the pattern of residential areas. The accuracy assessment of Land Use classified maps shows that the integration of remote and social sensing, using the decision tree and random forest methods, yields accuracies of 83% and 86%, respectively. Thus, this approach facilitates an accurate Urban Land Use classification. Urban Land Use identification can aid policy makers in linking human activities to the socioeconomic consequences of different Urban Land Uses.
