Embodiment Construction

[0060] The present invention first proposes a spatio-temporal analysis model construction method, which can serve for the monitoring of land use change. Most of the traditional land monitoring models use the simplest purely numerical statistical method to provide numerical monitoring (often just calling regression analysis); some may also take the spatial distribution into account, but often simply use the spatial distribution as a comparison of numerical statistics, There is no systematic time series comparison and cause exploration on the time series; some may consider the time information and spatial distribution information comprehensively, but the influence of various factors in the space within the period of time is not considered uniformly. Typical, such as national (or provincial, or municipal) major events in the economy (or administration, or transportation) and other aspects of the impact on land use change.

Abstract

The present invention is applicable to the technical field of land management, and provides a method for feeding back land use changes based on land spatiotemporal models, including: determining the land use category, land time series information and land space information of a target area based on time series land use data; Determine the land impact factor of the target area; based on the land use category, the land time series information, the land space information and the land impact factor, construct a quadruple land space-time model; based on the quadruple land A space-time model for generating a land use change curve in the target area; based on the land use change curve, predicting the land use change in the target area. The present invention can comprehensively reveal the recent land use change in the corresponding area, and predict the land use change in the area in the future, so as to provide reliable auxiliary information for land use and land planning decision-making in the country or region.

Description

technical field [0001] The invention belongs to the technical field of land management, and in particular relates to a method and system for feeding back land use changes based on land space-time models. Background technique [0002] In my country's current rapid urbanization process, the economy is developing rapidly, the quality of the population is improving rapidly, and the population in rural towns is migrating to cities and towns at an unprecedented speed. As a result, many advantageous resources (including educational resources, medical resources, leisure and entertainment resources) have gathered Land resources on which to carry out various economic behaviors and social activities in economically more developed regions have become typical scarce resources, which is especially reflected in the central urban areas of top-ranked first-tier or second-tier cities and new cities and new districts that are developing rapidly obvious. In the face of the increasingly scarce la...
