摘　　要：陕甘宁地区是中国经济相对落后的地区 ,从气候方面分析研究它的贫困影响因素 ,探讨扶贫措施有着现实的意义。采用陕甘宁地区 1971～ 2 0 0 0年间的气温、降水等气象资料并进行了分析 ,结果表明 :陕甘宁地区年平均气温以 0 .0 379℃ /a的速度递增 ,2 0世纪 90年代以来递增幅度更大 ,且冬季增温尤其明显。降水以 1.0 6 39mm/a的速度递减 ,但 80年代有上升趋势 ,90年代以来却成明显下降趋势。因此 ,2 0世纪 90年代成为陕甘宁地区近 30年间最暖干的时期。气候的日趋暖干必然对本区的工农业生产带来负面影响并导致该地区贫困现状的加剧 ,因此分析影响经济发展的气候因素 ,找出相互关系 ,制定合理的方法措施是陕甘宁地区扶贫项目的重要环节。Shaan-Gan-Ning area(short name for Shaanxi, Gansu and Ningxia Provinces of Northwestern China) is the major poor region in China with nearly 80 percent of the state-named poor counties in the area. The climatic change in the area is becoming warmer in accord with the global climate change. Based on data of temperature, precipitation in 1971～2000, the climate change in the area is analyzed. The results show that the mean annual temperature of the area increases at the rate of 0.0379℃/a and demonstrates a enlarging tendency on temperature increase since 1990s; the temperature increase in winter is more notable than that in other period; the annual precipitation decreases at the rate of 1.0639mm/a with the tendency of rising in 1980s and apparent dropping in 1990s. The warm-dry tendency of climate in the area results in negative impacts on local development and aggravates poverty in the region. Some countermeasures are put forth for the development in the region under this kind of climatic situation.
