Embodiment

[0043] Embodiment Input the scale index of a certain type of evaluation factor (such as business service center). Among them, the scale index is used to reflect the scale of the evaluation factor, which is usually obtained through comprehensive calculation of a series of indicators (such as the number of teachers in the school, the building area, etc.), and its calculation method is not the focus of the present invention. For details, please refer to the relevant land evaluation procedures. It can be recorded as SI, where the value range of SI is a real number of [0-100].

[0044] Step 2. According to the number N of evaluation factor objects, a two-dimensional plane grid with a size of N×N is constructed, and each evaluation factor object is randomly assigned to the two-dimensional plane grid.

[0045] The spatial position of each evaluation factor can be represented by row and column numbers (Row, Col). The implementation of the evaluation factor object assignment of the e...

Abstract

The invention relates to an assessment factor rating method for land resources based on an ant colony clustering model. The method comprises the steps of inputting indexes of scale of each assessment factor; establishing a two-dimensional planar grid according to assessment factor objects, and randomly distributing each assessment factor object on the two-dimensional planar grid; setting artificial ants and randomly distributing the artificial ants on the two-dimensional planar grid; and iteratively picking up and dropping the assessment factor objects in probability through the artificial ants so as to obtain a rating result of the assessment factor objects. The assessment factor rating method for the land resources based on the ant colony clustering model can automatically rate the assessment factor objects and provide technical support for rational use of the land resources.

Description

technical field [0001] The invention belongs to the technical field of automatic evaluation of land resources, in particular to a method for classifying land resource evaluation factors based on an ant colony clustering model. Background technique [0002] (1) Land resource quality evaluation technology [0003] With the advent of the 21st century, many global issues, such as population issues and food security issues, are becoming more and more severe. As a country with a large population, land resources are relatively scarce in China. How to use land rationally and realize the sustainable use of land resources is an urgent problem to be solved at present. Therefore, using scientific technical means and methods to evaluate the quality of land resources is a necessary means to promote the rational use of land resources. [0004] According to the definition of the Food and Agriculture Organization of the United Nations (FAO), land resource evaluation refers to the process o...
