The Studying Of Region Land Function Space Division

Land function space refers to a geographical space under the administrative jurisdiction, which is for the people to survive and practice.With the accelerating process of urbanization and industrialization as well as the rapid population growth, the demand for a variety of land use has risen sharply, making thecompetitive relation in the types of land use space more intense and leading a series of space issues, including an imbalance on region development, space development out-of-order, inefficient use of resources, environmental degradation and so on.In the context of developing Wild China, scientifically making adivision of land function space plays an important role inland exploitation, socio-economicdevelopment, environmental managementan dprotection, as well as improving people’s quality of life.Land functional assessment is the core content and important support of land space division.Land function spac classification system is the foundation of land function space adivision, and under the reference to the land functional classification at home and abroad, land space classification adopts two levelsclassification form according tothecharacteristics of land spacefunction.The first-levelclassification of land spaceincludes production space, living space and ecological space; and the second-level classification of land space includes agricultural production space, forest production space, production space livestock products, aquatic production space, industrial production space and urban living space, rural living space, space conservation and ecological leisure services space.We define the connotations of land functional evaluation and land space function division, and then establish the land functional evaluation system, obtaining the index weight with the method of AHP. To calculate the evaluation scores of the individualland function by the method of weighted summation, the evaluation scores of individualland functional higher, the land in the spatial expression ofvland space function stronger. Take the maximum score as the best expression to make a division of land space. Taking DaweiTown in Gangbei District, Guigang City, Guangxi as an example, with the evaluation unit of 1km×1km grid, make a comprehensive evaluation from the three aspects of the land function in production, life and Ecology.
