Abstract: Using CBERS-1 as information source,we derived the landscape data of Guiyang.Bivariate correlation analysis and partial correlation analysis showed the correlativity and extent of correlation between the landscape types and population density.There was an imperceptible contrast between bivariate correlation analysis and partial correlation analysis.The relationship between the landscape of habitation,building and population density was positive but not significant.The others had negative relationship with population.The landscape of farmland,woodland and lawn passed significant test.No significant correlation between the landscape of rock desertification and population density was observed.The landscape of water area and garden plot had no correlation with population density.Although human activity influence landscape pattern widely and profoundly as disturbance factor,population density didn't perform a decisive function.
