基于人体健康的 3种城市森林夏季林内紫外线照射环境特征比较研究
Comparing the Summer Ultraviolet Characteristics in the Shade of 3 Urban Forests Based on Human Health Effects
紫外线辐射对人体健康具有多种生物学影响,城市森林能够为居民提供温和的紫外辐射环境。为了了解林下紫外线环境特征是否存在树种间差异,对北京市夏季 3 种常见遮荫树种的林下紫外辐射(UV)强度、林内与林外UV辐射的比值(SR)、UVB在总UV辐射中占比(UVB/UV),以及VD合成和红斑效应两种人体作用有效辐射强度(UVVD、UVer)进行了测算。结果表明:(1)三种林分林内紫外辐射总量是林外的 3%—10%,不同林分的林内UV强度具有显著差异,元宝枫…查看全部>>
Ultraviolet(UV)radiation has multiple biological effects on human health,and urban forests can provide a moderate UV radiation environment for residents.In order to understand whether there are inter-species differences in the characteristics of UV environment in canopy shade,the UV intensity,the ratio of UV radiation in shade and in the open(Shade Ratio,SR),the proportion of UVB in total UV radiation(UVB/UV),and the intensity of two types of human-acting ef…查看全部>>
