| Abstract: | Based on the monthly average temperature data of 12 meteorological stations in the Three-River Headwaters Region of Qinghai Province from 1961 to 2010,the regional differences and abrupt changes of temperature variation were analyzed by the methods of moving average,linear trend analysis,spline interpolation,and Mann-Kendall test.Some important results were obtained in four aspects as follows.(1)The annual and seasonal average temperature in the Three-River Headwaters Region of Qinghai Province and its sour... |
