摘要：

本文对极区通量观测系统作了介绍,在国际极地年(IPY)全球协同观测中,极区通量观测系统在南极中山站进行了连续14个月的观测。结果表明,中山站年净辐射通量为12.9 W/m²。感热通量夏半年(10～2月)为正值,冬半年(3～9月)为负值,年平均1.9 W/m²。潜热通量全年都为正值,年平均11.2 W/m²。总体而言,地表通过净辐射获得热能,又通过感热和潜热方式向大气输送。观测得到的CO₂通量全为负值,年平均为-0.031 mg/m²,表明南极中山站是CO₂汇。

A polar regions flux observation system is introduced in this paper.The system worked continuously for 14 months at ZhongShan Station in Antarctica during International Polar Year(IPY)global coordinated observation.The results show that the annual average net radiation flux is 12.9 w/m2 at ZhongShan Station.The value of average sensible heat flux in summer halfyear(from October through February)is positive whereas negative in winter halfyear(from March through September)and the annual average sensible heat flux is 1.9.w/m2 The values of average latent heat flux in summer and winter are both positive and the annual average latent heat flux is 11.2.w/m2 As a whole the ground surface obtains energy by means of net radiation and transfers energy to the atmosphere by means of sensible heat flux and latent heat flux.The observing value of CO2 flux is negative which means ZhongShan Station in Antarctica is a CO2 sink region.
