| 摘 要： | 近百年来,全球气候发生了以气温升高为主要特征的显著变化。东北是中国的重要粮食主产区,气候变化将可能加剧东北地区水资源短缺情势,进一步影响到国家的粮食安全。以辽河流域为对象,分析了近60年来降水径流变化特性,采用水文模拟方法,揭示了河川径流变化成因,基于假定气候情景,研究了河川径流量及土壤含水量对气候变化的响应。结果表明:铁岭站实测径流量自20世纪60年代中期以来,总体呈明显的阶段性减少趋势,人类活动是河川径流减少的主要原因。降水增加比减少对河川径流量的影响明显,土壤含水量对降水减少的响应更加敏感,气候暖干化趋势将非常不利于东北地区的水资源利用和农业生产。

| Abstract: | The enhanced greenhouse gas effect is expected to cause high temperature increase globally,and this would lead to an increase in precipitation in some regions while other regions would probably experience reduction in precipitation.The impact of expected climate change will affect almost all the sectors of human endeavor,among which,water resources is the most direct and important sector.North-eastern China is scarce in water resources,while the region is main food source area of China as well.Climate chang... |
