Abstract: This is a case study in which data are collected from Bijie in Guizhou Province and geographically weighted regression is performed,with comparison with OLS,to explore the influence of economic,social and natural factors on population density.Results demonstrate that economic and social factors have larger impact on population distribution than natural factors.Altitude does not influence population distribution significantly while slope does.There is negative correlation between population distribution and economic strength,urbanization level,transportation and terrain conditions.Medical conditions have positive influence on population distribution.Therefore in the future Bijie should enhance city and town construction,strengthen the ecological immigration and protect natural resource and environments to optimize population distribution.

摘要: 山区人口分布受多种经济、社会等非空间因素的影响外,还与不同区域的地理分布有密切关系。文章以贵州省毕节地区为例,以乡镇区域为研究单元,运用地理加权回归(GWR)分析方法,兼与全局普通二乘法(OLS)方法进行比较,研究人口密度和经济、社会、自然等因素的空间相关关系。研究表明,社会经济因素对毕节山区人口分布的影响大于自然环境因素的影响;海拔对毕节山区人口分布的影响不如坡度的影响显著;综合经济实力、城镇化水平、交通条件和地形条件的好坏与其对人口分布的影响大小呈反相关,而医疗条件的好坏与其对人口分布的影响大小呈正相关。因此,"加强城镇建设、鼓励人口聚集,加强生态移民工作、保护资源环境"是未来毕节地区相关政策的基础。
