An Analysis on Spatio-temporal Evolution of Human-land Interaction in China Based on Big Data

Human-land Interaction has remained as the core of geographical study for long and is regarded as the significant base of the progressing territorial space planning in China. The utilization of multi-source data to represent the spatial distribution and spatial-temporal movement of human beings so as to build a relationship model between human and land factors is of great significance to optimize the spatial pattern of land, rational allocation and efficient utilization of natural resources. In this essay, the supply of urban construction land and population data of various types in China in the past 10 years is systematically reviewed, and the spatio-temporal coupling relationship between human and land, such as the man-land relationship index and the strength of inter-city connection, is calculated, which promotes the construction of analysis methods and theoretical conclusion on Human-land interaction under the new data environment, effectively serving the compilation and implementation supervision of territorial space planning.
