The Study Of Urban Morphology Zoning Based On GIS And "Housation"

City are within the scope of a certain geographical space entity, and its generation, the formation and development are inherent in space order and a specific spatial development patterns, urban elements of the spatial distribution of the material characteristics of the different geographic environment will evolve into different styles of city morphology.In this paper, both at home and abroad through the town forms a synthesis of research and geographic information systems applications in urban planning a synthesis, pointing out that layers of depth are observed in this study question the basic way; from practice to practice, cycle repeated continuously, and gradually increase to solve the problem of this study are the basic methods;Chengdu City area as an example, from the macro, meso and micro perspective of the three forms of city control of the study; from a macro level to control the total amount of urban construction, meso level through the establishment of morphological partition model, to facilitate city planning and management; from the micro-level, considering the configuration of public facilities in town, on the form of partition fine-tune the relevant indicators.Secondly,this article introduced the first "housation" the concept of using vegetation systems research methods, to study urban planning to provide a new approach, the property was the core of city building space to expand the original discrete data through spatial expansion Ways to continuous data and discrete data analysis, and that it will help promote our city to find land on the relationship between the relevant data to help us control over-exploitation of land in town,Finally, based on the VB6.0, the application of "wave front" principle, the use of grid-based data, the floor space was expanded to program design, in accordance with the contents of this paper were designed building statistics module, block statistics module, building density statistics module, floor area ratio statistics module, the average low-rise architecture statistics module as well as related indicators of space expansion modules, and program design.
