Study On Natural Division Of Highway In Yunnan Province

Through the study of natural divisions at home and abroad for reference, this paper, according to the zoning of the basic theory, principles, methods, etc., and refer to the existing natural geography and highway construction in yunnan province on the premise >f information, data, graphics, etc, the implementation experience of highway construction and practice in our country, as well as the related technical documents of highway construction specifications and requirements, including water and electricity, construction, railway and geology, and so on various projects department, the definite target in the research of yunnan highway natural regionalization, establishing and perfecting the highway natural regionalization research system and research type, at the same time, developed districts research methods and research principles.Through continuous efforts, complete natural divisions in yunnan province and research and development in yunnan province highway natural regionalization information system software.Presented in conformity with the practical situation of yunnan province highway natural regionalization research ideas and research framework of technical route scheme, provincial highway natural regionalization type system can be divided into three categories:highway natural individual divisions, special natural regionalization and highway natural regionalization.Perfect the provincial highway natural regionalization and the principle of special zoning system, method system and level units.According to the domestic and foreign various natural divisions, departments and various, special regionalization, the present study combined with practical experience and relevant regulations and requirements of highway construction, put forward and meet the requirements of the highway construction in yunnan province natural regionalization is established and the special division of division index system.Comprehensive application in highway natural regionalization advanced GIS technology and the technology platform, and use the powerful spatial analysis function of GIS provides, the landform, climate, rock and soil, hydrological, geological disasters such as natural geographical factors superposition of spatial data analysis, operation and spatial interpolation, etc, for the natural environment parameters or highway natural regionalization index partition.
