【摘要】 根据黑河下游额济纳绿洲柽柳灌丛波文比-能量平衡法的实测资料,分析了该地区的辐射特征,研究了热量平衡各分量的变化特征及热量平衡规律。在绿洲内部,其太阳辐射、净辐射具有明显的日进程和季节变化规律;太阳辐射月总量最大值(2133325.0kW.m-2)出现在6月份,最小值(133325.0kW.m-2)出现在10月份;在柽柳灌丛生态系统的热量平衡中潜热通量占能量支出量的62.85%,感热通量占32.85%,土壤热通量占4.44%。在日变化中,潜热在上午大于感热,在下午,由于湍流加剧,感热交换大于潜热。更多还原

【Abstract】 According to the data of long-time series observation to the Tamarix.spp Boscage Radiation and Heat balance,the radiation characters and quantity of sensible heat and latent heat or heat balance law in Ejinaqi were analyzed,some results were obtained:sun radiation and net radiation showed the obvious daily and seanonal diversification.The max.month radiation was 133325.0kW·m-2,and appeared in June,however the min.month radiation was 133325.0kW·m-2,and appeared in Oct.About 32.85% of total heat spent was sensible heat flux,about 4.44% of total heat spent was soil heat flux.The heat flux diversification law of days was: latent heat flux big to sensible heat flux in forenoon,sensible heat flux big to latent heat flux in afternoon.更多还原
