鼓浪屿疗区紫外线特征分析

Feature analysis of ultraviolet rays at Gulangyu convalescent area

目的为了把握鼓浪屿疗区紫外线照射强度的变化规律,更好地指导疗养工作,我们于2006-08—2010-08对鼓浪屿疗区紫外线进行为期4年的监测。方法利用美国生产的Davis 6162EU型自动气象站在鼓浪屿疗养区中心地带定点连续测定紫外线,每30 min取平均值采集数据1次。结果 4年中紫外线指数最大值为13.6;在晴空条件下,紫外线日变化规律呈以正午时分为最高点的对称抛物线型;春季、夏季、秋季中午前后的紫外线指数大于5,冬季(12—02月)紫外线指数基本在3以下。正午时分紫外线指数最大值大于10的主要分布在每年的06—08月。结论鼓浪屿疗养区紫外线丰富,要根据不同季节的气候特点合理安排疗养生活。冬季一般不需要做紫外线防护;春、秋季节中午前后3～4 h不宜户外活动;而夏季气温高、紫外线强,要采取严密的防紫外线措施。

Objective To grasp the varied regularity of ultraviolet(UV) rays intensity in Gulangyu sanatory distirct and instruct recuperating work better,the varied regularity of UV rays in Gulangyu sanatory distirct was mensurated from 2006 August to 2010 August.Methods UV rays in heartland of Gulangyu sanatory distirc was mensurated with Davis 6162 EU type automatic meteorological station made in USA,average value of UV index was taken every 30 minuts.Results The top UV index value is 13.6 In 4 years;In fair weather,varied regularity of UV rays intensity in daytime present with the symmetry parabola type which the biggest value was at noontide,in front and back of noon UV index was above 5 in spring,summer and autumn,in winter here(December,January,February),UV index was almost below 3.At noontide the biggest value of UV index is more than 10 mainly distributed in June,July and August.Conclusion The UV rays in Gulangyu sanatory district was abundant,recuperative open air life may be arranged reasonable according to dissimilarity season of the weather characteristics.In winter,don't need to do UA rays protection;In front and back of noon isn't proper for 3～4 hours doing outdoor activity in autumn and spring;In summer,air temperature was high and the UV rays was strong,need to adopt rigorously measure to defend UV rays.
