Embodiment Construction

[0045] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0046] This embodiment provides a method for evaluating the quality of land space utilization in urban agglomeration areas. figure 1 It is a flowchart of a method for evaluating the quality of land space utilization in an urban agglomeration area according to an embodiment of the present invention. Refer to figure 1 Steps S101 to S104, the evaluation method uses the fuzzy membership function model to standardize the data of urban agglomeration-scale land space quality evaluation, and comprehensively uses three objective weighting methods: entropy weight method, standard deviation method and CRITIC method to comprehensively Determine the weight to improve the objectivity and scientificity of weight d...

Abstract

The invention provides an urban agglomeration region land space utilization quality evaluation method and device. The method comprises steps that an excel work book format data file is acquired, and data of the data file is extracted; a fuzzy membership function model is employed to carry out dimensionless processing on original index data to generate standard index data corresponding to the original index data; an entropy weight method, a standard deviation method and a CRITIC method are employed to determine corresponding a weight value of an index respectively, and an average value of the weight values determined by the three methods is taken as a final index weight value; a measuring and calculation model corresponding to the index is utilized, and the index value corresponding to the index is calculated according to the standard index data and the final weight value. Through the method, a problem that an index weight value determined through an analytic hierarchy process or a delphi method can not objectively and scientifically reflect the influence degree of the index on the result is solved, and weight determination objectivity and scientific property are improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for evaluating the quality of land space utilization in urban agglomeration areas. Background technique [0002] The construction process of the land space utilization quality evaluation index system is a process of continuous negation, continuous improvement and spiral upward. After six constructions successively, the index system for evaluating the quality of land space utilization in urban agglomeration areas was finally determined. The design principles of the indicator system are: (1) Pertinence principle: according to the land space characteristics of the urban agglomeration area, it is different from the national scale, the city area scale and the urban built-up area scale, and grasps the problems and important characteristics of the urban agglomeration land space, based on this Create evaluation indicators. (2) Feasibility principle: the data can be ob...
