【摘要】：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 n T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。
[Abstract]:Objective: to investigate the probability of longevity and the intensity of geomagnetic field in various villages of Bama County, Guangxi, and to study the effect of geomagnetic environment on longevity. Methods: a household questionnaire was used in different villages in Bama County, Guangxi. Ask village cadres and other ways to verify the number of elderly people aged 85 and above; use a high-precision intelligent magnetometer to test the geomagnetic intensity of the corresponding villages and towns; and then draw a map of the spatial distribution of long-lived people in Bama based on GIS(Geographic Information systems technology. Finally, the relationship between geomagnetism and the probability of longevity was studied. The geomagnetic intensity of the "longevity colony area" (mainly distributed in the rock mountain zone) and the "non-longevity colony area" (mainly located in the hilly area of the earth slope) is generally higher than that of the "non-longevity colony area" (the geomagnetic intensity of the "longevity colony area" is generally higher than that of the "non-longevity colony area". The relationship between the variation of local magnetic intensity and longevity rate is a "power window" curve: when the local magnetic intensity is less than about 46650 NT threshold, The probability of longevity increases with the increase of geomagnetic intensity, and when the local magnetic intensity exceeds the threshold, The probability of longevity decreases with the increase of geomagnetic intensity. Conclusion: the curve between the probability of longevity and the intensity of geomagnetic field is consistent with the "power window" characteristic of the biological effect of magnetic field. It is speculated that geomagnetic field may be one of the important factors influencing the longevity of Bama population in Guangxi.
