Urban Spatial Growth and Thermal Environmental Effects Simulation

With the rapid progress of urbanization, urban environmental problems have become increasingly complicated, dynamic and challenging. Many studies have been developed to address these problems by using the simulation of urban spatial growth, such as, cellular automata model [1,2], multi-agent model [3,4] and the integrated application of other models. Study on thermal environment is the main method of single channel, including atmospheric correction method [5,6] and single window method. The Single window method consists of Single window algorithm [7-9], Universal single channel algorithm [10], Split window method, Multi channel algorithm [11] and Single channel multi angle and multi channel multi angle method [12]. Along with, the regression analysis was used to analyze the urban thermal environment, and the construction, land use and other factors were used as regression analysis [13,14], etc. Simulation of urban thermal environment effect mainly concentrated Soil Vegetation Atmosphere Transfer model [15], ENVI-met model [16-18], Community Land Model [19] and General space model [14], etc.

Therefore, this study will use geospatial data and statistical surveys and other data sources, combined with technology and methods of cellular automata and geographic information systems, urban spatial systems to simulate the growth of urban and its thermal environmental effects [20]. We intend to focus on three perspectives:

a) The three-dimensional space-time urban spatial growth differentiation and driving mechanism;

b) Methods of three-dimensional model of urban spatial growth simulation; and
