| 摘 要： | 通过对ＧＡＭＥ－Ｔｉｂｅｔ野外工作期间所得藏北高原一个年周期的土壤温度资料的初步分析，发现藏北高原１９９７￣１９９８年冬半年土壤日温差的分布存在明显的异常现象；指出了这种异常现象的发生可能与藏北高原１９９７年冬天的特大雪灾有关。从浅层土壤日温差的异常变化，定性地说明了藏北高原１９９７￣１９９８年冬半年不同地点雪灾的严重程度，但由于受资料的限制，目前尚无法进行定量的评估。

| Abstract: | The preliminary analysis of the ground temperature in Northern Tibetan Plateau shows thatthe distribution of the daily range of the ground temperature during the winter season in 1997-- 1998 isanomalous. Such phenomena may be related to the snow disaster occurred in Northern Tibetan Plateau inwinter, 1997. Based on the anomalous variation of the ground temperature in shallow layer, the snow disaster conditions on different sites of Northern Tibetan Plateau in winter season of 1997-- 1998 are evaluated qualitatively. However, they cannot be evaluated quantitatively due to the data restriction. |
