A method and device for evaluating land use

Abstract

The invention discloses a land utilization evaluating method and device which are used in the technical field of land programming. In some feasible embodiments of the invention, the method comprises the steps of: determining a reference evaluating object of a three-dimensional utilization form, wherein the reference evaluating object comprises at least one kind among building three-dimensional utilization, three-dimensional traffic construction and three-dimensional greening; setting a utilization form index and a utilization benefit index of the reference evaluating object, wherein the utilization form index and the utilization benefit index are respectively an index of the three-dimensional form; and based on the utilization form index and the utilization benefit index of the reference evaluating object, constructing a land utilization evaluating model. According to the technical scheme of the invention, the reference evaluating object of the three-dimensional utilization form is adopted, so that the method is suitable for cities developing in three dimensions, and the requirement of land space high-efficiency and intensive utilization under a city three-dimensional development condition is met.

Description

technical field [0001] The invention relates to the technical field of land planning, in particular to a land use evaluation method and device. Background technique [0002] In the history of urban development in the world, urban expansion for hundreds of years is a flat pattern based on the theory of flat urban development. This pattern emphasizes the arrangement of urban production and living space on the ground as the base. With the accelerated development and industrialization of human society, the rapid advancement of urbanization and the shortage of urban land resources, in the context of rapid urbanization, urban development has experienced the evolution process of "first plane, then ground, and then three-dimensional development". At present, urban development has changed from a stage of quantitative expansion relying solely on land and population to a new stage of further deepening and development of urbanization that places equal emphasis on structure, quality, and...

Problems solved by technology

However, at present, the planar land development management technology based on the two-dimensional spatial thinking model is often used for land use evaluation. The planar land development management technology based on the two-dimensional spatial thinking model cannot systematically support the investigation, evaluation, and evaluation of spatial resources under the three-dimensional use of land. Planning cannot be applied to cities that develop in a three-dimensional direction

For example, the planar land development management technology in the two-dimensional spatial thinking mode cannot express the quantity and form of space resources under the three-dimensional utilization mode, cannot evaluate the potential and suitable use of space resources, and cannot realize the rational allocation of space resources for production and living needs, etc. As a result, it is impossible to realize the optimal allocation, dynamic simulation and real-time early warning of land space resources under the three-dimensional utilization mode, which seriously restricts the development of the three-dimensional utilization of urban land space in my country at the technical level.

[0003] To sum up, the traditional planar development management technology based on the two-dimensional spatial thinking mode can no longer be applied to cities developing in a three-dimensional direction
