Research On The Regional Development Intensity Predict Based On The Cellular Automaton

Regional development intensity refers to a building space area proportion of thetotal area, it is the basic means to control the amount of construction land and realizespatial structure optimization, it is the main functional area planning need to calculatethe key indicators.Shenbeixinqu as an important city of Shenyang northern expansion space in thenorth new district, is new type industrialization demonstration zone in Shenyangeconomic zone, it is the bridgehead of Shenyang economic zone radiation northeastAsia. With the economic development in old industrial base in Northeast China andaccelerating construction of Shenyang economic zone, urban space expand Shenyangland use change in the future will be the most direct performance, regionaldevelopment space problem, in the development process of regional developmenttiming problems, and the problem such as the land contradiction conflict, so this paperchose Shenbeixinqu as a typical research case.On the basis of the major function oriented zoning about the developmentintensity problem research idea, this paper integrated use the GIS and RS technology,through the simulation of regional land use change and forecast, forecasted the futurestrength of regional construction land distribution and development. The article isdivided into five parts:The first part illustrates the research background and research significance of thisarticle, by analyzing the problems existing in China’s economic and socialdevelopment, especially the urban spatial expansion, the contradiction between supplyand demand of urban construction land, etc., putting forward the necessity of regionaldevelopment intensity prediction research;The second part from the development intensity, development of land suitabilityand the construction land expansion in the domestic and foreign research aboutdevelopment strength and the comprehensive development in the summary of thesystem, summed up the research on regional development intensity predictioninstructive experience;The third part focused on the key technical problems of the regional developmentintensity prediction, based on binding CA-Markov model mainly included the research, the key link of development intensity projection, etc.;The fourth part carried on the empirical research, the application of a model inthe north new district of Shenbeixinqu regional development intensity predictionresearch, through the Shenbeixinqu related to land in the north new district planning,urban planning and urban construction land in the relevant part and index analysis andevaluation, to determine the binding limiting factor, and prohibited developmentregions to set hard for the CA-model binding factors, on the basis of the dynamicmechanism of urban sprawl and urban expansion mode is analyzed and suitabilityassessment, and finally simulate the most likely urban form in the short period,putting forward the optimal solution of urban construction land expansion;The fifth part summarized the regional development strength of the bindingCAMarkov prediction, researched the relevant data and predicted results of ofregional development strength.
