摘要
将内蒙古东四盟分为4个区,以每个盟为一个区分析土壤墒情变化。结果表明,降水量呈下降趋势,下降幅度为20%～46%,下降顺序为呼伦贝尔、兴安盟、赤峰、通辽。植物生长季气温呈上升趋势,升温幅度为0.2～0.7℃,受气候变化影响,内蒙古东四盟土壤墒情呈下降趋势干旱严重程度依次为呼伦贝尔、兴安盟、赤峰、通辽。
Eastern four leagues in Inner Mongolia were divided into four regions, the variation of soil moisture was analyzed with every league as one region. The results indicated that precipitation showing decrease trend, the amplitude was 20% -46% , the order was Hulunbeier, Xing＇ an League, Chifeng and Tongliao. The temperature in plant growing season showed increasing trend, the amplitude was 0.2 - 0.7 ~C. Affected by climate change, the soil moisture in eastern four leagues showed decrease trend. The severity of drought degree was in order： Hulunbeier, Xing＇ an League, Chifeng and Tongliao.
