| 摘 要： | 根据1961-2009年秦岭南北57个站点的月降水资料,采用区域旱涝指标和Z指数,运用Mann-Kendall检验、小波分析、Kriging插值等方法,对秦岭南北旱涝时空变化趋势进行分析。结果表明：①关中地区年平均气温倾向率大于陕南,气温突变年均为1996年。②近49年来,关中地区暖干化及春旱、夏涝的趋势较陕南显著。气...

| Abstract: | Based on the monthly precipitation data observed by 57 meteorological stations in the Qinling Mountains during the period from 1961 to 2009,this paper analyzes the temporal and spatial trends of drought and flood in the north and south of the Qinling Mountains and the response of regional drought index and Z index to global climate change using mainly the M-K mutation test,wavelet analysis and Kriging interpolation.The conclusions are as follow:(1) Climate trend rate of average annual temperature in Guanzho... |
