Multi-classifier fusion-based land unused condition prediction method and device

Abstract

The invention discloses a multi-classifier fusion-based land unused condition prediction method. The method includes the following steps that: step A, training sample plots are selected, the characteristic data of the plots are extracted, the plots are manually divided into unused plots, used plots and undetermined plots according to land unused condition standards; step B, with the characteristic data of the training samples adopted as classifier input and the categories of the training samples adopted as desired output, a plurality of different classification models are trained separately; step C, the characteristic data of a plot to be predicted are extracted and are inputted into a plurality of classifiers, the classification results of the plurality of classifiers are obtained; and step D, a confidence-based classifier fusion method is adopted to fuse the classification results of the plurality of classifiers, so that the land unused condition prediction result of the plot to be predicted is obtained. The invention also discloses a multi-classifier fusion-based land unused condition prediction device. With the multi-classifier fusion-based land unused condition prediction method and device of the invention adopted, land unused conditions can be accurately predicted, and therefore, scientific basis can be provided for the use, planning and management of land.

Description

technical field [0001] The invention relates to a land idle prediction method and device based on multi-classifier fusion, and belongs to the technical field of urban land planning. Background technique [0002] With the growth of urban population and economic development, urban spatial expansion is an inevitable development trend, but the accelerated development of urbanization has also led to the lack of construction land resources, frequent occupation and waste of urban land has become a problem faced by the state and local governments. common problems. To protect land resources, land resource management plays an important role in urban planning. Lack of land resources is a typical land problem, and idle construction land should be discovered and utilized in a timely manner. [0003] Many land databases have been built all over China, especially with the great improvement of GIS (Geographic Information System) technology, the size and reliability of data have made great...

AI Technical Summary

Problems solved by technology

On the one hand, this method is inefficient; more importantly, the existing technology can only judge whether the land is currently idle based on the idle land standard manually or by computer, but cannot scientifically and accurately predict the future land use trend
