Homestead utilization information acquisition method based on multiple methods

Abstract

The invention provides a homestead utilization information acquisition method based on multiple methods, and the method is characterized by comprising the following steps: S1), selecting a village A located in the southeast of Guangxi and in a semi-hilly plain region and a village B located in the north of Guangxi and in a mountain and hilly region as typical case sites; s2) the village domain layer data mainly comprises remote sensing image data of two villages, land utilization current situation data, land utilization change data and social economic data; s3) based on remote sensing image data; s4) along with the continuous development of market economy, the peasant households are continuously changed from highly homogenized pure peasant households to heterogeneous facultative households; and S5) dividing the village A into five districts a, b, c, d and e according to the distribution characteristics of the village A, the village B and the natural station. According to the homestead utilization information acquisition method, the homestead utilization attribute table can be formulated, and the optimized regulation and control path and mechanism innovation of homestead utilization transformation are provided based on detailed data of land parcel investigation and home-entry investigation.

Description

technical field [0001] The invention relates to the technical field of remote sensing image information extraction, in particular to a multi-method-based homestead utilization information acquisition method. Background technique [0002] With the rapid advancement of industrialization and urbanization, the rural homestead management system is not perfect, and the problems of inefficient use of rural "multiple houses for one household", excessive occupation of homesteads, vacant and abandoned homesteads, etc. are more prominent and are intensifying. As a non-contact information acquisition technology, remote sensing technology, especially the current development of high-resolution remote sensing, has significant advantages such as cost saving and short acquisition cycle compared with traditional ground actual surveys and visits. However, the current technology for automatically extracting information on "empty and abandoned rural housing sites" from high-resolution images is ...
