忻州市近50年气候变化特征分析

为了研究气候变化的区域差异，合理开发利用区域气候资源，更好地改善农业生产环境，利用忻州市15个站点1963—2012年地面气象观测资料，对忻州市的气温和降水的时空变化趋势进行了统计分析。结果表明：（1）河曲、五台、五寨年平均降水量回归系数为负，表现为下降趋势；忻府区、繁峙年平均降水量回归系数为正，表现为上升趋势。（2）忻州市年平均气温突变基本都发生在20世纪90年代，并且气温都呈上升趋势。

The Analysis of the Climate Characteristic of Variation in Past 50 Years in Xinzhou City

In order to study the regional differences in climate change and rational development and utilization of climate resources, better improve agricultural production environment. Based on the observation data of 15 meteorological stations from 1963 to 2012 in Xinzhou City, the spatio-temporal changes of temperature and precipitation trends were analyzed. Results showed that: (1) Hequ, Wutai, Wuzhai regression coefficient was negative for the downward trend in annual average precipitation, and Xinfuqu, Fanshi average annual precipitation in regression coefficients were expressed as an upward trend. (2) The temperature mutations had occurred in the 90’s of the last century in Xinzhou City, and it temperatures showed an upward trend.
