【摘要】 根据1993年10月至1994年12月天山积雪遥感监测结果,着重分析了天山西部、中部和玛纳斯河流域积雪状况。研究结果表明,天山西部积雪面积波动幅度大于中部。西部和中部积雪时间变化特征相似,但是中部积雪面积和雪量小于西部。玛纳斯河流域3个垂直带的积雪覆盖率随海拔而增加,月平均最大覆盖率出现时间随海拔而推进。更多还原

【Abstract】 On the basis of satellite monitoring of snow cover in the Tianshan Mountains during the period from October, 1993 to December, 1994, this paper is intended to analyze the conditions of snowcover in the west and central sectors of the Tianshan Mountains and Manasi River basin. The results show that the amplitude of variation in snowcover areas in the west sector is larger than those in the central sector. The temporal variation of snow covers in the west sector is the same as that in the central sector. Snowcover areas and amounts in the central sector are less than that in the west sector. The snow covere of the three vertical zones in the Manasi River basin increase with their elevations, while the time when the monthly mean maximum of snow covers appear delays with the increase of elevation in the Manasi River basin.更多还原
