山区人口分布与环境要素关系的定量分析
Quantitative Analysis on the Relationship Between Population Distribution and Environment Factors in Mountain Area
摘要
Abstract
[ Objective ] The aim was to analyze the relationship between population distribution and environment factors in mountain area quantitatively. [ Method] Taking the contiguous area of Sichuan, Yunnan and Guizhou Province as study object, population density and residential point density were chosen as the indexes of population distribution, and the quantitative relationship between population distribution and environment factors (including altitude, topography relief amplitude, land use, road network and river network ) in mountain area was analyzed. [ Result ] Altitude and topography relief amplitude in mountain area had obvious negative correlation with population density and residential point density, and the correlation coefficients with population density were -0.731 and -0.743; residential points were fewer in the region far from rivers, but there was no obvious correlation between population density and river network density; residential point density was higher in cultivated land and construction land, and population density had obvious positive correlation with the area proportions of cultivated land and construction land, with the correlation coefficients of 0. 895 and 0.726; the more distant from road, the smaller residential point density, and there was obvious positive correlation between population density and road network density, with the correlation coefficient of 0. 823.[ Conclusion ] The study could lay a foundation for the further development of Spatiality of population data in study region.关键词
