Village function type identification method and device

Abstract

The invention provides a village function type identification method and apparatus. The method comprises the steps of collecting and checking village land utilization type vector data; merging and extracting the land utilization type vector data step by step, and measuring and calculating the function intensity of the merged land utilization type vector data; and performing clustering analysis and discriminant analysis on the village land utilization type function intensity, and quantitatively identifying the village function type. According to the method, the problem of relatively high subjectivity of weight assignment species due to index selection in a constructed index system is avoided; the village function type identification accuracy is improved; the problems of index selection dimension intersection, high data acquisition difficulty and the like in traditional village classification are avoided, and the village function type identification efficiency is improved; when data arrangement is carried out, urban and rural regional spaces and production and living spaces in villages are effectively distinguished, and the production and living regional spaces in the villages are effectively distinguished, so that the research of external leading functions of villages is more accurate, and the method has greater significance for practical guidance.

Description

technical field [0001] The invention belongs to the technical field of village function classification, and in particular relates to a method and device for identifying village function types. Background technique [0002] At present, the research on rural functions mostly adopts the evaluation method. Firstly, according to the cognition of scholars, the top-down prediction of the rural function types is carried out, and the quantitative evaluation indicators are selected according to the characteristics of each function type, and the evaluation index system is constructed. Through AHP or entropy The value method assigns weights to each index, and obtains various functional strength values ​​of villages through comprehensive calculation. Although this technology can realize the quantitative evaluation of village functions, due to the subjective nature of function type prediction, evaluation index selection, index weight assignment, etc., it is greatly affected by the researc...

AI Technical Summary

Problems solved by technology

Although this technology can realize the quantitative evaluation of village functions, due to the subjective nature of function type prediction, evaluation index selection, index weight assignment, etc., it is greatly affected by the researcher's personal factors; and due to the availability of data, most studies use The county is the smallest research unit, and it is impossible to effectively distinguish between urban and rural spaces, resulting in complex functions of villages. There is no effective method for quantitatively identifying villages that is more convenient and fast
