西藏高原人体舒适度指数时空变化特征分析
Spatial and temporal variation characteristics of comfort index of human body in Xizang Plateau
摘要
Abstract
Based on daily meteorological data from 38 meteorological stations from 1981 to 2020 and climate da-ta with a spatial resolution of 30 seconds(approximately 1 km2)from 1970 to 2000 in the Xizang Plateau,China,we analyzed the temporal and spatial variation characteristics of the comfort index of human body(ICHB)and comfort index of human body in plateau(PICHB).The results showed that:(1)Over the past 40 years,the ICHB in Xizang showed a noticeable upward trend.The overall increase rate of ICHB in the Xizang Plateau was 0.76·(10a)-1,with regional increase rates ranging from 0.57·(10a)-1 to 0.98·(10a)-1.(2)The annual and seasonal in-crease rates in ICHB followed the order,west>north>northeast>southeast>central and southern edge,and winter>autumn>spring>summer.(3)The PICHB indicated a cold and extremely uncomfortable environment,with severe plateau reactions mainly distributed in the mountains of the northern,western,and northeastern regions of the Xi-zang Plateau.Cold,uncomfortable,and severe plateau response areas were mainly distributed on the northern,central,and southern mountain edges.The cold,uncomfortable,and moderate plateau response areas were mainly distributed at lower altitudes on the northern,central,and southern margins.Cool,uncomfortable,and mild pla-teau response areas were mainly distributed southeast and east of the southern edge.Areas that were neither cold nor hot,felt comfortable,and had no plateau reactions were mainly distributed in southern Cona County and southern Medog County.In general,with the warming and humidifying climate trend in the Xizang Plateau,the ICHB significantly increased,and the PICHB shifted to a more comfortable state.关键词
