1青藏高原东北部树木年轮记录揭示的最高最低温的非对称变化显示文摘江河源区自然环境严酷,生态系统脆弱.近年来由于该区域日趋严重的生态环境问题使之逐渐成为全社会所广泛关注的焦点地区.根据采自青藏高原东北部黄河源区西顷山和阿尼玛卿山的祁连园柏树轮样芯,重建了研究区过去近425a来冬半年的最低温和近700a来夏半年最高温.1578~1940年的近400a间研究区冬半年最低温度的波动较为平缓,但是自1941年来以来有急剧的升温趋势.夏半年最高温在20世纪末表现出明显的升温趋势.近425a来最高温和最低温的变化存在非对称现象.最高温和最低温在近425a来的变化非常相似,但最低温的变化比最高温的变化超前大约25a左右.如果在未来30a内最高温和最低温的变化保持过去近425a来的相关趋势,那么在未来30a内,最高温也将继续剧烈升温.勾晓华 陈发虎 杨梅学 Gordon Jacoby 方克艳 田沁花 张永 2007中国科学(D辑)2007,37,11:19
2Asymmetric variability between maximum and minimum temperatures in Northeastern Tibetan Plateau:Evidence from tree rings显示文摘Ecological systems in the headwaters of the Yellow River, characterized by hash natural environmental conditions, are very vulnerable to climatic change. In the most recent decades, this area greatly attracted the public's attention for its more and more deteriorating environmental conditions. Based on tree-ring samples from the Xiqing Mountain and A'nyêmagên Mountains at the headwaters of the Yellow River in the Northeastern Tibetan Plateau, we reconstructed the minimum temperatures in the winter half year over the last 425 years and the maximum temperatures in the summer half year over the past 700 years in this region. The variation of minimum temperature in the winter half year during the time span of 1578―1940 was a relatively stable trend, which was followed by an abrupt warming trend since 1941. However, there is no significant warming trend for the maximum temperature in the summer half year over the 20th century. The asymmetric variation patterns between the minimum and maximum temperatures were observed in this study over the past 425 years. During the past 425 years, there are similar variation patterns between the minimum and maximum temperatures; however, the minimum temperatures vary about 25 years earlier compared to the maximum temperatures. If such a trend of variation patterns between the minimum and maximum temperatures over the past 425 years continues in the future 30 years, the maximum temperature in this region will increase significantly.Jacoby GORDON 2008Science China Earth Sciences2008,51,1:19
