鄱阳湖流域气候变化及其对入湖径流量的影响OACSTPCD
Climate change and its influence on runoff in Poyang Lake watershed
为分析鄱阳湖流域气候变化特征及评估其对流域径流的影响,研究利用1961-2010 年间鄱阳湖流域29个气象站和入湖"五河"水文控制站观测数据,分析该时段内流域气候和径流量变化趋势,建立统计模型分析其对流域径流量的影响. 研究结果表明:鄱阳湖流域年气温呈显著性( 99%置信度检验)波动上升趋势,流域降水总体呈略上升趋势,降水天数呈下降趋势. 受气候变化的影响,鄱阳湖流域径流量呈上升趋势. 统计模型计算结果表明,径流量与降雨变化呈非线性关系,径流量对…查看全部>>
In order to assess the effect of future climatic variation on runoff , the paper analyzed the temporal and spatial variation trends of climate and established a statistical model to study its impacts on the runoff by using the observational data of weather station and the annual runoff series (1961-2010 ) of five hydrologi-cal gauging stations within Poyang Lake watershed .The results indicated that annual temperature presents the obvious rising trend;it pre…查看全部>>
