In this paper, a simulation model of pedestrian flow based on geographical cellular automata, GCAP Model, is established. The GCAP Model takes the walking suitability of the roads into consideration, and uses six dynamic parameters to simplify tactically the decision-making process of pedestrians in their movements. The simulation results show that the model is quite sensitive to different road conditions...
Rapid industrialization and urbanization of China have deepened the conflicts of the land supply and demand. In this transition period, there occur many changes to the land utilization. Central and local governments should make prompt effective and scientific planning and control of land use to satisfy requirements of economic and social development. Taking Xinbei district of Changzhou city as the...
Based on the advantages of single model in the field of land use simulation, This research construct a Markov-logistic-CA integrated model to reflect the land use change precisely considering both sides of macroscopic and microscopic factors. The conventional CA model is extended from two aspects including iteration times and conversion rules by Markov and Logistic respectively. Finally the integrated...
Land use change is not only related to some natural, social and economic factors, but also influenced by land use structure, policies and value orientation, and the influence of driving factors are spatially unstable. To make the simulation of land use patterns more reasonable and accurate, CLUE-S model is applied and improved. The authors use GWR instead of logistic regression to build a regression...
It is a hot issue of current research that how to strengthen the land use management, so that resources and environmental capacity, land development costs and industrial construction and agricultural production would be spatial balanced to promote regional sustainable development in rapid urbanization and industrialization process. A Case Study in Langfang city of Hebei province was made. Based on...
In this paper we emphasize on the technology research depending on the CA model which have powerful computation function and spatial analysis ability of GIS to simulate and forecast urban land use change in Shenzhen city. We reconstructed and extended conventional CA model from three aspects including model run-time, influencing factors, transforming rules and finally integrate GIS into CA model by...
Urban planning is human purposeful, conscious social activity. It is influenced by nature and human society. Research of urban planning and urban space expansion is in the forefront of global urban research, and is one of the hot topics. China is troubled by population growth, lack of resources, ecological and environmental degradation, and rational urban development is closely related to sustainable...
