| 摘 要： | 使用线性回归、趋势倾向性和空间相关等方法对比分析内蒙古辖区蒙古高原东部呼伦贝尔与南部额济纳旗地区器测时段气候变化特征。结果表明，呼伦贝尔与额济纳旗两地器测时段全年和生长季（6—9 月）平均温度增温显著，降水无显著共同变化，区域暖干化趋势明显。年径流总量变化、空间相关结果和周期分析显示，两地气候干湿变化具有同步趋势。全球变暖背景条件下，内蒙古东部沙地樟子松和西部胡杨面临着相近的气候环境与人类活动双重压力。

| Abstract: | Characteristics of climate changes in the Hulun Buir region and Ejina Banner during theinstrumental period, Inner Mongolia, were analyzed by the methods of linear regressions, trendsand spatial correlations. Our results indicated that significant warming trends existed in annual andgrowing seasonal mean temperatures in both regions, while no significant common trends existed inprecipitation. Variations of four annual runoff series, results of spatial correlations and period analysesshow a synchronous trend in wet and dry climate conditions existed in the eastern and southernMongolian Plateau. The effects of climate-related environmental pressure and human activities stresson the forest in the eastern and western Inner Mongolia are still serious under the global warmingbackground. |
