| 摘 要： | 利用吉林通榆“干旱化和有序人类活动”长期观测试验站2002年10月~2003年12月在退化草地下垫面获得的近地层湍流通量及能量的连续观测资料(样本间隔30min),分析了半干旱地区退化草地下垫面近地层能量的日变化、季节变化特征;同时还讨论了干湿季转换期及不同季节近地层能量收支特征,以及天气状况对近地面层能量收支的影响。 |
| 关 键 词： | 退化草地 近地层能量 日变化 季变化 |

| Abstract: | By using the observation data collected at long-term field experiment station on aridification and ordered human activity during the period of October 2002-December 2003, the diurnal and seasonal variations of surface energy flux on degraded-grassland over semi-arid area have been analyzed. And the near surface energy budget also has been discussed during different seasons and the transition period between dry and wet season, and also including the impact of weather. |
| Keywords: | degraded-grassland near surface layer energy budget diurnal and seasonal variation |
