摘要: 以CBERS1为数据源,获取贵阳市景观数据,通过简单相关和偏相关分析,从定量角度阐明人口密度和景观类型之间的相关关系和相关程度。结果表明,简单相关分析和偏相关分析的差别很小,不能影响变量之间的相关关系;相关分析中,只有居民点及建设景观与人口密度为正相关,且相关关系不显著,其他均为负相关,其中农田景观、林地景观、草地景观为显著相关,石漠化景观相关性不显著,水域景观和园地景观可视为无相关性;人类活动对自然界景观格局的影响虽然广泛而深刻,但以人类干扰景观为主,人口密度对景观格局不存在决定性的作用。

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.
