Embodiment Construction

[0024] The specific technical solutions of the present invention are further described in the accompanying drawings of the structural description below.

[0025] as attached figure 1 As shown, a multi-method-based homestead utilization information acquisition method of the present invention includes the following steps:

[0026] Select two typical villages, formulate homestead utilization attribute tables, rely on the detailed data of land parcel survey and household survey, and use remote sensing image data interpretation and participatory rural assessment method to obtain the spatial and attribute data of rural households’ homesteads, and obtain the rural households’ Homestead spatial data and attribute data, establish the association between spatial data and attribute data, build a "farmer-homestead" database, and use this to invert the evolution process of typical village homesteads in different historical periods, and explore the process of farmers' livelihood differentia...

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 ...
