Relation between Leukemia and Types of Topograpay in Jiangxi Province

通过对地形地貌资料4502个数据，白血病死亡调查资料2239例，研究了白血病死亡率与人群生存区的地形地貌类型（山区、丘陵、岗地、平原）的相关性。结果表明，山区、岗地、平原与白血病死亡率有明显的相关性，等级相关系数分别为-0．1963（P＜0．05），0．2925（P＜0．0025），0．3122（P＜0．0025）。

This paper presents the studies on the relativities between mortality of leukemia and types of topography(mountain, hill, mound and plain) in the living areas of people by means of 4502topographic data and 2239 examples of investigation about the death caused by leukemia.The result showed that the mountain, mound, plain and mortality of leukemia was obviously correlated,correlation coefficient of gradation was - 0. 1963(p< 0.05),0. 2925(p<0.0025),0.3122(p< 0. 0025).
