摘要
利用汾河流域静乐站1970-2004年的气温、降水及径流资料,建立多元非线性回归模型,分析径流变化对区域气候变化的响应,结果表明,径流对降水的响应比气温敏感,且径流变化是气候因子和流域下垫面条件共同作用的结果。
By using the precipitation, temperature and runoff data of Jingle hydrometric station during 1970- 2004,multiple regressive models were established and response of runoff to region climate change was analyzed. The results show that the tesponse of runoff to precipitation is more obvious than to temperature, and runoff variety is the joint results of the climate factor and underlying surface.
