中文摘要	采用非随机试验,运用图示分析法、序列试验法、区域对比试验法、区域回归试验法,分析了2002-2004年冬春季在河西走廊东部武威市进行的焰弹人工增雪作业.试验发现：增雪效果显著,增加降雪量12.5 mm,增加水量为7.75*108 m^3,平均相对增雪率为40.2%.并对武威市冬春季人工增雪季节、布点和增雪时机等进行了探讨.
英文摘要	Wuwei City is located in the east Hexi Corridor in Gansu Province, the north of the Qilian Mountains, south of the Tengger Desert, and west of the western margin of the Loess Plateau, in the study area it belongs to the moderate continental arid climate, the annual precipitation in the main farming areas varies in a range of 100-160 mm, and more than 80% of precipitation occurs mainly during the period from May to October. The water supply for industrial, agricultural and domestic purposes relies basically on stream water of the Shiyang River recharged by the glacial-snow melt water from the Qilian Mountains and groundwater. Along with global warming, the elevation of snow-line in the Qilian Mountains is increased, the precipitation variability becomes high, the precipitation in winter and spring is reduced, the shortage of water becomes more and more serious, and the ecological environment has been seriously degenerated. Therefore, artificial rainfall/snowfall is an effective way. This paper analyzes the data of artificial snowfall experiment in Wuwei City in the east Hexi Corridor, Gansu Province in winter and spring during the period from 2002 to 2004 by means of non-random experiment, such as the diagram analysis, sequential test, regional comparative experiment and regional regression test. The results reveal that the effect of artificial snowfall was quite well, the snowfall was increased by 12.5 mm, the increased water volume was 7.75*10^8 m^3, and the average relative increase rate of snowfall was 40.2 %. The seasons, distribution of operation sites and time of artificial snowfall in Wuwei City are discussed.
