摘要
近些年来，全球气温变暖已成为一个全世界广泛关注的问题。民勤属于我国最典型的干旱荒漠化地区。文中对民勤荒漠区1961—2007年气温和降水资料进行了分析，结果表明：民勤沙区近47年的年平均气温增高幅度高于全国水平。在过去47年当中，2月份平均气温增高3．01℃，这一增加幅度在其他文献中未见报道，当地冬季趋暖现象明显。近47年来当地降水增加的趋势并不显著，干旱期占据了植物的整个生长季节。
In recent years, the global temperature warming has become a world widespread matter of concern. Minqin county is the most typical arid desertification area in china. This research has carried on the analysis to temperature and the precipitation material in 1961 -2007 in Minqin desert area. The results indicated： the average temperature increase was higher than the national level near 47 year in Minqin desert area. Average temperature of February increased 3.01℃. Winter warming phenomenon was obvious in locality. Precipitation increase tendency was not remarkable in the recent 47 years, and the dry spell occupied entire vegetation growing season.
