摘要: 依据祁连山海北高寒湿地植物生长期观测资料,分析了区域辐射收支情况及其变化特征.结果表明:祁连山海北高寒湿地有较强的太阳总辐射(DR),但地表反射辐射(UR)、地面有效辐射(ELR)较低;地表长波辐射(ULR)、大气逆辐射(DLR)、净辐射(Rn)均较高,且具有明显的日、季节变化.植物生长期5~9月的日变化振幅DR>Rn>UR>ULR>DLR>ELR,其总量表现出ULR>DLR>DR>Rn>UR>ELR,分别达4650.6、4225.5、3058.8、2156.2、477.6和425.1 MJ·m-2.从月际分布来看,ULRDLRDR最高出现在7月,Rn出现在6月,UR出现在5月,ELR出现在8月,分别为980.3、913.1、721.5、554.9、112.1和127.4 MJ·m-2.

Abstract: In this paper,radiation balance and changing characteristics on alpine wetland in Haibei Prefecture of the Qilian Mountains were analyzed according to long-term observation data in growing season.The results showed that there were higher total global solar radiation(DR),lower surface reflected radiation(UR) and lower surface effective radiation for the alpine wetland,as well as higher long-wave radiation(DLR),atmospheric inversion radiation(ULR) and net radiation(Rn).Their diurnal and seasonal variations were pronounced.As regards the diurnal variation during growing season(from May to September),the order was DR>Rn>UR>ULR>DLR>ELR,however,as regards the total quantity,the order was ULR>DLR> DR>Rn>UR>ELR,with the values of 4650.6,4225.5,3058.8,2156.2,477.62 and 425.1 MJ·m-2,respectively.In light of monthly variations,the month maxima of ULR,DLR and DR were in July(950.1 MJ·m-2);those of Rn,UR and ELR were in June,May and August.The values of ULR,DLR,DR,Rn,UR and ELR were 980.3,913.1,721.5,554.9,112.1 and 127.4 MJ·m-2,respectively.

Key words: growing season, Haibei Prefecture in the Qilian Mountains, alpine wetland, radiation balance
