Study On The Land-saving Mode Of The Spatial Form In Mizhi County

There are some problems exists in the development of small towns in Northern Shaanxi Loess Plateau. Such as the space scale expansion caused ecological damage,extensive land utilization caused the unreasonable spatial structure,the high degree of spatial fragmentation making low efficiency. Therefore, how to construct a scientific and rational land mode is particularly necessary。The study of the subject is the county seat of Mizhi, the goal-oriented is the harmonious man-land relationship.Based on the above knowledge and ideas, thesis research problem, purpose and significance are described. Through literature review related to the research and application of domestic and foreign order, summarize the research perspective and starting point. Technical methods and theory and research papers were introduced. And then summarizes the purpose and significance of the research. Secondly, in theory, based on research and introduction presentation, the paper Mizhi county land resources of the background conditions made a presentation and make summarize its characteristics. Using technical methods of land use status quo was calculated analysis and feature summary. Land use status quo here, including the status of the land status of the internal space of external borders and land forms. Mizhi County land from the current situation analysis, summary Mizhi county land-use issues in the construction of development. Furthermore, to solve these problems, the paper constructed from two aspects Mizhi County land external borders model, and the internal space of Mizhi County land form mode, respectively. By ecological suitability assessment, classification dimension estimation, and other research and land external borders; compactness by land evaluation, land complex relationship analysis and spatial integration capabilities, etc., on a variety of assumptions simulated scenarios to determine land inside space Form. And by studying the relationship between spatial form Mizhi county land elements of the construction of Mizhi county land space form synthetically relational model.Finally, according to the above-constructed spatial form Mizhi county land mode, the status quo Mizhi County Mizhi county building and planning 2014 edition, generate Mizhi County land plan.By examining the land program for Mizhi county land mode feedback and adjustment. Hoping to guide land development Mizhi County, northern Shaanxi and provide reference for studying other forms of small towns and land space.
