摘要: 本文利用NOAA/AVHRR卫星资料分析了章古台地区不同生境的反射率及地表温度,并研究了防护林体系对辐射平衡和表面温度的影响。结果表明,固沙造林可使辐射平衡由占总辐射的46%提高到57%,白天地面有效辐射由占总辐射的35%减小到29%,表面温度日较差由13.0—14.0℃减小到2.0—3.5℃。

Abstract: In this paper, reflectivity and surface temperature in different biotypes of Zhanggutairegion are analysed in terms of NOAA/AVHRR data, and the effects of shelterbelt system on radiation balance and surface temperature are also studied. The results indicate that the percentage of radiation balance in the shelterbelts for sand fixation increases from 46% to 57% of the total, that of surface effective radiation decreases from 35% to 29%, and the range of surface temperature is also decreased from 13.0—14.0℃ to 2.0—3.5℃ during the daytime.
