中文摘要: 利用晋中市近49年的气候和水资源等资料,对气温、降水的变化特征以及由此引起
的水资源量的变化进行了统计分析。结果表明:年平均气温整体呈上升趋势,平均以0.3℃/10
年速率上升,气温偏高主要是冬季,夏季变化幅度不大。降水量的变化呈减少趋势,以35.9mm/10
年的速度在递减,1990年代是降水量减少幅度最大的时期;水资源总量、地下水、河川径
流量呈减少趋势,与降水的变化具有明显的一致性。
Abstract:Based on the climate and water resources data of Jingzhong , Shanxi Pr
ovince for recent 49 years, the change characteristics of temperature, precipita
tion and water resources are analyzed. The results indicate that the annual mea
n temperature is rising at a rate of 0.3 ℃/10a, and the increasing mainly occur
s in winter. While, the precipitation is decreasing at a rate of 35.9mm/10a, wit
h the largest decrease in the 1990s. The water resources, groundwater and river
runoff all tend to decrease, which are consistent with the changes of precipitat
ion.
