| 目的：调查、测试广西巴马县各村人群长寿发生几率和地磁场强度，初步研究地磁环境对人群长寿的影响。方法：在广西巴
马县境内不同村庄，采用入户调查问卷、询问村干部等多种方式核实长寿（85 岁及以上年龄）老人数量；用高精度智能磁力仪测试
相应各村镇的地磁强度；然后基于GIS（Geographic Information Systems）技术绘出巴马长寿老人的空间分布图，最后研究巴马地
磁和长寿发生几率之间的变化关系。结果：（1）巴马长寿老人空间分布呈非均匀性, 县境内存在" 长寿集落区"（主要分布在石山
地带）和" 非长寿集落区"(主要分布在土坡丘陵地区)；（2）" 长寿集落区" 的地磁强度普遍比" 非长寿集落区" 的高；（3）地磁和
长寿率之间的变化关系呈" 功率窗"曲线：当地磁强度小于约46650 nT 阈值时，长寿发生几率随地磁强度的增加而升高；当地磁
强度超过该阈值时，长寿发生几率随地磁强度的增加而减少。结论：巴马长寿发生几率和地磁强度之间的变化曲线符合磁场生物
效应的" 功率窗" 变化特性，推测地磁场可能是影响广西巴马人群长寿的一个重要因素之一。 |

| Objective:The longevous population and the earth's magnetic field of Bama county in Guangxi province of China
were investigated and measured in order to learn the influence of the Earth's magnetic field on the longevity of the people.Methods:The
numbers of the longevous people who were 85 years old and above were obtained via survey questionnaire and inquiring some cadres in
the villages of Bama. And the magnetic fields were measured by using a high precision magnetometer. Then the geography distribution of
the longevous population in the villages of Bama county was mapped. Finally the relationship between the percentage of the Longevous
population and the earth's magnetic field of Bama County was studied.Results:(1) The spatial distribution patterns of the longevous population
are uneven in Bama county. There are a few "longevity areas "and "Non-longevity areas", where the percentage of longevous
population of the former is much higher than that of the latter; (2) The percentage of the longevous population living in mountainous region
are usually higher than those in slope areas.（3）The curve of the change relationship between the earth's magnetic field and the percentage
of the longevous population presents the shape looked like a "power windows": The longevous percentage raises with the increase
of the strength of the earth's magnetic field which are less than about 46650nT, and decrease as the earth's magnetic field are beyond
46650 nT.Conclusion:The variation relationship between the percentage of the longevous population of the villages and the earth's
magnetic field in Bama corresponds to the change characteristic of the magnetic bioeffects. It means that the earth's magnetic field is
probably one of the important factors influencing the geography distribution of longevous population in villages of Bama county. |
