Abstract

The invention provides a land comprehensive evaluation method and device based on a TOPSIS entropy weight method. The method comprises the steps: obtaining the original data of a target region according to a pre-constructed evaluation index model, and carrying out the standardization processing of the original data, and obtaining the standardized data; performing information entropy calculation on the standardized data by adopting a preset calculation model to obtain the information entropy of each evaluation index, and obtaining the weight of each index according to a preset calculation formula; and in combination with the standardized data and the weight of each index, calculating by using a preset linear weighting model to obtain a land comprehensive evaluation result of the target region. By implementing the method, comprehensive and comprehensive quantitative evaluation can be provided for the development of a national development region, and data support is provided for subsequently formulating targeted related policies and measures and promoting the development region to improve and transform.

Description

technical field [0001] The invention relates to the technical field of land evaluation, in particular to a method and device for comprehensive evaluation of land based on the TOPSIS entropy weight method. Background technique [0002] The development of the development zone represents a new economic growth pole to a certain extent, and it is an exploration and test area for a new economic development model. Carrying out development evaluation research and grasping the development status and existing problems of national-level development zones is of great significance for subsequent formulation of relevant policies and measures and promoting the upgrading and transformation of development zones. [0003] The research on the development evaluation of development zones mainly focuses on the countermeasures of development problems, the evaluation of land intensive use, the planning of development zones, and industrial clusters. However, as a complex system, the development sta...
