摘　　要：利用海晏县气象局1997~2017年气象资料及海北牧业气象试验站土壤湿度观测资料,对青海湖北岸土壤湿度变化及土壤干旱发生规律进行分析,结果表明:青海湖北岸春季干旱发生概率较大,夏季土壤干旱发生概率最大,且程度明显偏重,秋季是一年当中土壤含水率最好的时期,土壤干旱发生的概率很小。Based on the Meteorological bureau of Haiyan County from 1997 to 2017 and the soil moisture observation data of Meteorological experi mental station for animal husbandry in Xihai Town,on the north shore of surrounding QingHai lake soil moisture change and soil drought occurrence regulation analysis.The results show that the probability of drought in spring is relatively high,and the probability of drought in summer is the highest,and the degree of drought is obviously excessive.Autumn is the period with the best soil moisture content in a year,and the probability of drought in soil is very small.
