| New century, China entered the era of urbanization, the city's sustainable development requires a reasonable growth of urban space, but the current theory for the development of China's urban space research lagged behind the actual planning. With the acceleration of urbanization process, as well as the urban population and land size continues to expand, urban land use structure has also undergone changes.Evolution of urban spatial structures reflect the progress of science and technology as well as social structure, economic structure and political structures change. Spatial structure of urban areas as a set of applied and theoretical basis for integrating research, revealing the evolution of the shape space structure and mechanism of the corresponding control theory, control mode and measures. Urban systems research focus is to reveal the history and evolution of objective things, dynamic mechanism to predict the future development of urban space and the evolution of the path.In this paper, the geographical point of view of space-time simulation, based on SLEUTH model of comprehensive use of GIS, Markov theory, cellular automata and spatial economics, to build regional space model their evolution. In the model to urban areas, transportation and other spatio-temporal data, based on historical change based on the regional geo-spatial evolution of the rules extracted; the use of cellular automata based on the SLEUTH model and the stochastic simulation of regional geography cellular growth, reproduction and die. Respectively, and Tangshan of Hebei Province Baoding City, the simulation of regional spatial and temporal evolution of empirical research, its evolution and the evolution of the mechanism of the regional space-depth analysis of the Baoding and Tangshan City, the idea of regional spatial structure optimization and strategy.Chapterâ… Introduction part of the first chapter. Background on the significance of the study at home and abroad discussed the current situation, and the evolution of regional spatial analysis of the feasibility of simulation.Chapterâ…¡The evolution of regional spatial structure of theoretical basis. Description of geographical simulation system and the evolution of regional spatial structure of the link pairs of cellular automata for structural systems were systematically explored.Chapterâ…¢The expansion of the SLEUTH model theory. SLEUTH model analysis describes theoretical approaches and the main ideas, as well as the essential element of model construction. Chapterâ…£Based on SLEUTH model to Baoding, Hebei Province based on remote sensing image data such as the evolution of regional spatial simulation model to do a preliminary empirical study of the theory. Discusses and analyzes the evolution of spatial structure of Baoding in urbanization, margination, and the expansion of cluster effects. Through the regional spatial structure and status quo analysis of the evolution of cities and counties out of the merger in favor of regional spatial development of Baoding. The city into the major cities around the county-level city administrative areas are conducive to the integration of administrative centralization and resource development, regional planning and coordinated development enabler.Chapterâ…¤Baoding mechanism and the evolution of regional spatial structure optimization. Baoding city space under the future structure of the optimization ideas and strategy formulation of regional spatial development and appropriate measure.1.City-oriented development strategy. Major cities of economies of scale generated in the process will lead the overall development of the region; taking into account the optimization of the layout of downtown land in order to enhance the strength of downtown.2.1nto Beijing, Tianjin,Hebei economic circle. Baoding city-oriented development process, needs to upgrade the industrial structure and industry aggregation degree of acceleration of urbanization process, through integration into the economic development of Tianjin and Hebei circle, sharing resources, complement each other as well as through inter-regional competition to improve their efficiency and competitiveness of advantage. The core of the city through economic circle of radiation and the proliferation of functional capabilities to promote their cities.3.Promoting coordinated regional development. Baoding regional spatial development trends, the expansion of space for the Baoding has laid a solid foundation, but also for the connection of the Beijing-Tianjin Shi laid a solid economic base.4.Optimize the productive forces, enhance the degree of industrial aggregation. To strengthen the construction of marginal zone Industrial Base to promote the sound development of the outlying areas of cities.Chapterâ…¥Hebei Province based on data from remote sensing images, based on distribution characteristics of geological disasters, using SLEUTH model the evolution of Tangshan City Regional Space simulation and prediction. Analysis of simulation results derived terrain slope huge impact on urban development, Tangshan City, north of the mountains and hills, landslides and other geological disasters, the region's urbanization rate is far lower than other regions. Description topography and geological disasters on the development of urbanization has significant impact.Chapterâ…¦Through the period the Tangshan city planning, combined with models to predict the results of analysis to explore the development of Tangshan new trend of regional space. Tangshan urban space from the previous centralized crowding together style, and gradually form a space for the overall development of the three-chip models; the focus gradually shifting coastal cities. According to the process of urban development that exist in geological disaster prevention, land use planning and urban development issues in the discussion on the promotion of regional spatial development of Tangshan suggestions: 1.Optimize the industrial structure. Reasonable on regional spatial planning, through cities and towns groups, Jidong coastal areas, central city 3 focus on the development sub-regional planning, straighten out the central city and the county, towns, industrial relations between points, and gradually form a the coordination of the regional spatial pattern.2.Rational urban planning group structure. The establishment of the urban area as the center, and coastal county Metro as a link to towns, backed Organized Group model. Constructed to the central area as the main body, to the southern coastal city with a belt and the northern Piedmont city's urban development pattern for the two wings, medium cities and small towns to promote the coordinated development.3.Speed up the inter-urban road construction. Combination of Tangshan City, the layout of the features of the road traffic system of unified planning, improve the road between the various groups and the urban transportation system within the road traffic system planning.4.Strengthening regional cooperation. Beijing and Tianjin North to strengthen the coordinated development of regional economic development in the Bohai Sea. Through the coordination of development, accelerate the production elements together, forming industrial development, two-way and open a new advantage; the formation of the pattern of coordinated development of industries.Chapterâ…§Summarizes the conclusions and outlook of the regional space-based SLEUTH model the evolution of the model and the main conclusions of the study shortcomings.The main contribution of this study in the following areas:1.Learn geography,economics, and other multi-disciplinary theory, the SLEUTH model, based on the introduction of systems science and complexity of scientific thought to simulate the regional spatial evolution of regional spatial structure study has provided new research perspectives and theoretical basis.2. Evolution of the regional spatial structure built on the basis of the study on the urbanization of regional spatial development patterns are discussed. Theoretical study and closely integrated empirical analysis presents a more complete study of ideas and build a new set of regional spatial' structure of a research framework.3.Baoding, Hebei Province systematically discussed the evolution of regional spatial structure and mechanisms, in-depth analysis of urban spatial structural change in the status quo and existing problem, a right of regional spatial structure optimization of Baoding countermeasures and suggestions, with a certain degree of practical significance.4. In the geological hazards based on the analysis of Tangshan City Regional Space evolution of the simulation and prediction. Tangshan periods through the analysis of urban planning in Tangshan City in conjunction with the status of the development process put forward the regional spatial development of Tangshan City, countermeasures and suggestions.
