摘　　要：该文运用GIS空间分析方法和数理统计方法,分析我国北部沿海、东部沿海和南部沿海综合经济区人口空间分布与其相关因子(自然和经济因子)间的定量关系,筛选与人口分布密切相关的关键指标并建立人口数学模型,最后对模型进行精度验证,分析该区域人口分布的特点及其影响因素。本文具体结论如下:(1)北部沿海综合经济区人口分布特点:地势平坦的内陆平原地区和沿海地区经济发达,交通便利,人口分布较为密集,内陆山地、丘陵地区人口分布稀少;(2)东部沿海综合经济区人口分布特点:人口分布整体比较密集,特别是交通便利、经济发达的地区人口分布尤为密集;(3)南部沿海综合经济区人口分布特点:内陆河流分布密集、积温较低的地区人口分布较为密集,积温较高、丘陵低地区域人口分布稀少。According to the national region economy division standard, dividing the China＆#39;s coastal zone into the north coastal synthesizes eco-nomic zone, the eastern coastal synthesizes economic zone and the south coastal synthesizes economic zone. In various regions, analysing the ration re-lations of the population spatial distribution characteristic and correlation factors through theory, method and technique, putting forward the key index which have close correlation with population spatial, establishing the population mathematical model, finally verifying the precision in various regions population model, and analysing the population distribution characteristic and the factors which affect various regions population distribution. The verification method includes independent-samples T-test and the correlation analysis of model-population and census population. The conclusion is below：1.The north coastal synthesizes economic zone, Key factors： GDP, rail, river and area of plain, Population model：（x1 is GDP, x2 is rail, x3 is river,x4 is area of plain） The result of T-test： the value of sig is 0.334 which is bigger than 0.05, the value of F is 0.949, and the value of R2 is 0.6679;The characteristic of population distribution：the distribution of popu-lation is denseness in the inland-plain and coastland where the hypsography is evenness, the traffic is convenient and economic is develop, and sparseness in the in the hill and inland-mountain.2.The eastern coastal synthesizes economic zone.Key factors： GDP, area of plantation, and area of residential;Population model：（x1 is GDP, x2 is area of plantation,x3 is area of residential）The result of T-test：the value of sig is 0.290 which is bigger than 0.05, the value of F is 1.147, and the value of R2 is 0.6668;The characteristic of population dis-tribution：the whole distribution of population is denseness, especially more denseness in the zone where the traffic is convenient and economic is de-velop.3.The south coastal synthesizes economic zone,
