【摘要】 运用甘肃省长江流域11个气象站1971～2000年30年整编气象资料及5个农业气象观测站1981～2000年1m土层内的土壤湿度资料,分析了该地大(暴)雨发生频率及大(暴)雨易发时段不同深度层次的土壤含水量、可容纳水量的变化,构造了评价当地大(暴)雨引发泥石流的评价指数。结果表明:在发生大雨时,西汉水流域的泥石流发生可能性大于白龙江流域,发生暴雨时,白龙江发生泥石流的可能性大于西汉水流域。更多还原

【Abstract】 Based on the meteorological data of 11 weather stations in 1970-2000 and the data of soil moisture of 5 agrometeorological observation stations in 1981-2000, the frequency of heavy rain and storm and the variation of soil water content and potential soil water content were analyzed. The index which is used to assess possibility of mud-rock flow had been created. The results showed the possibility of mud-rock in Xihan River valley is larger than Bailong River valley under the heavy rain while the possibility of mud-rock in Bailong River valley is larger than Xihan River valley under the storm.更多还原
