摘要
人类的健康长寿主要依赖于遗传、生活习惯以及环境等因素,其中环境是影响长寿现象的重要因素之一。对江苏省如皋市长寿人口的空间分布研究表明,如皋市90岁以上长寿人口比率的空间分布具有地域聚集特征,比率较高的区域分布在北部-东部-东南部发育较强的壤质雏形土和人为土上,在中西部的砂质雏形土和南部弱发育的年轻壤质-粘质雏形土上,比例较低。这种分布特征与土壤中的有效硒、锌和硼等微量元素空间分布特征相似。相关分析和主成分分析结果表明,如皋市土壤中有效态硒、锌和硼与90岁以上人口比例均达到极显著相关,并归属于同一主成分,表明这些元素或组合可能是该地区对健康长寿有益的主要微量元素。
Health and life-span of a person mainly depend on factors such as inheritance, living habit and environment. Among the three factors, environmental is an important one affecting the phenomenon of longevity. The study on spatial distribution of the density of longevous people of Rugao County, Jiangsu Province, shows that the over-90 rate （ number of people over 90 years old per 100 000 in population） is high in some areas. It is higher in areas of well-developed loamy Cambosols and Anthrosols in the northern, eastern and southeastern part of the county than in areas of sandy Cambosols in the western part and areas of clayey and weakly-developed Cambosols in the southern part. According to the correlation and principal component analysis, available Se, Zn and B in soils were significantly correlated with the over-90 rate, and belonged to the same principal component, indicating that available Se, Zn and B or their combination in the soil of Rugao are probably the most important trace elements beneficial to the health and the life-span of the people in Rugao County.
