贵州喀斯特高原人口分布的自然环境因素——Ⅱ多元回归分析与地带性研究

以贵州喀斯特高原76个县市(区)农业人口密度、人口密度以及自然地理因素的资料为基础,主要应用多元逐步回归方法研究贵州省人口分布与其主要影响因子的相关关系,并建立多元回归模型,针对贵州喀斯特地区的自然地理因素分布具有一定地带性,综合研究这些地带性因素的分布特征,探讨贵州喀斯特地质条件下人口分布的自然地带性规律,其结果表明:在喀斯特地质环境条件下,受经度、纬度以及平均海拔高度之间错综复杂的相互影响关系的作用,决定了贵州高原人口分布疏密差异的态势,表现为西北部人口过密,东南部人口稀疏的空间格局,使经济、社会、生态发展也呈现出不协调的状况.

Natural Environmental Factors of Population Distribution in Guizhou Karst Plateau:Multiple Regression Analysis and Zonality

Based on the data including agriculture population densities,population densities and natural geography factors from 76 counties in the Guizhou karst plateau,the paper mainly uses regression method to analyze the relationship between population distribution and main influence factors,and a multiple regression equation has been established.Aiming at some zonality in the distribution of natural geography factors in the GuiZhou karst area,we have a comprehensive analysis of the characteristic of their distribution to discuss the zonality regulation of population distribution.The result shows: Under the condition of karst geology environment,because the complex influence of the relationship among longitude,the latitude and average elevation mutually,the dense and sparse situation of population distribution in the Guizhou plateau is formed: the denser in the northwest area,the sparser in the southeast,which makes it immoderate in economy,society,ecosystem development.
