摘  要：
Based on the natural environmental features in the Guizhou Karst Plateau,in this paper the correlations between the population distribution and the natural environmental factors including average altitude,karst geological conditions,etc.are analyzed using correlation analysis,and the difference of population distribution in different karst areas and the factors affecting population distribution and migration are also analyzed so as to reveal the geographical factors affecting population distribution in the Ghuizhou Karst Plateau.The results reveal that the unique mountainous plateau topography and the karst geologic conditions are the main factors resulting in the complexity and vulnerability of natural environment,and also the main factors affecting population distribution and migration in Guizhou Province.Population distribution in the province is mainly affected by the elevation,landforms,topographic slope and the climatic, hydrologic and vegetation conditions,which is similar to that in other regions.However,there are also some differences in population distribution,for example,the population density does not decrease with the increase of elevation,that is,the regions with high elevation are densely populated,but the places with low elevation is sparsely populated except the regions with elevation over 1 600 m a.s.l.The unique karst geologic and geomorphologic conditions restrict the population carrying capacity of lands and the population migration in Guizhou Province.The population distribution is also affected by the proportion of area of soil erosion under the joint effects of elevation,slope,fluvial erosion,climatic and geologic conditions,etc.
