1Response of runoff to climate change and its future tendency in the source region of Yellow River显示文摘这研究检验水文学和来源区域的气象学的数据从 1956 ~ 2010 的黄河和从地区性的气候的未来气候情形当模特儿(摘要) 在 20102020 期间。通过分析流动变化并且揭示气候原因,它为未来流动预言变化趋势。年度吝啬的流动显示出一个减少的趋势在,这被发现最近在有 5a, 8a, 15a, 22a 和 42a 的伪时期的黄河的来源区域的 50 年;削弱的华南海夏天季风导致了降水减少,以及蒸发增加并且在全球温暖的情形冻结土壤退化是气候因素,它引起了流动减少。基于地区性的气候模型摘要预言,在黄河的来源区域的流动是可能的在下一 20 年里通常减少。Li Lin Shen Hongyan Dai Sheng Xiao Jianshe Shi Xinghe 2012Journal of Geographical Sciences2012,22,3:11
2May-June mean maximum temperature change during 1360-2005 as reconstructed by tree rings of Sabina Tibetica in Zaduo,Qinghai Province显示文摘Based on tree-ring samples collected from Zaduo area in southern Qinghai Province, a 646-year ring-width series was established. Using response function, correlation function and partial correlation analysis we found that the ring-width series is sensitive most to May and June mean maximum air temperature at Zaduo meteorological stations and the correlation is significantly negative. Therefore, May-June mean maximum air temperature in Zaduo area since 1360 is reconstructed using this ring-width series. The regression equation was cross-validated in the calibration period of 1961-2005. The calibration equation can explain 59.8% of the total variance. Since high temperature could reinforce evapotranspiration and result in water stress, the high values are more reliable than the low values in the reconstructed series. By further analyzing upon the reconstructed series, it shows that on the in-ter-annual scale there are 6 periods with higher temperature: 1438-1455, 1572-1612, 1684-1700, 1730-1754, 1812-1829 and 1853-1886; while there are 5 periods with lower temperature: 1547-1571, 1701-1729, 1755-1777, 1830-1852 and 1887-1910. There is no significant rising of temperature in recent 50 years. By comparison with the rings-width series nearby which are also sensitive to the mean maximum air temperature and the mean maximum temperature reconstruction by ring-widths, it is found that the variation of inter-annual scale is fairly common in the region.SHI XingHe QIN NingSheng ZHU HaiFeng SHAO XueMei WANG QingChun ZHU XiDe 2010Chinese Science Bulletin2010,55,26:8
