摘要: 选取西藏东南部原始林区9个典型气象站资料,分析林区气候变化特征。结果表明:1954—2009年,藏东南林区年平均气温升高0.9℃,其中冬季升温高达1.47℃,升温突变点出现在2001年;林区年降水量增加了185 mm,其中春、秋季节分别增加83 mm、55 mm;藏东南林区气候趋于暖湿化;藏东南林区气温和降水的变化比我国东北、华北、西北等地显著,且海拔越高越显著。

Abstract: Based on the meteorological data collected at nine typical stations in the forestry region of southeast Tibet, the climate change in the region was analyzed. The results show that the annual mean temperature in southeast Tibet forestry region increased about 0.9℃ from 1954 to 2009, in particular the increment of mean temperature in winter was 1.47℃. According to the Mann-Kendall test, the abrupt change of annual mean temperature occurred in 2001. Meanwhile, the annual precipitation in the forestry region has distinctively increased 185 mm during 1954-2009, most of the increment happened in spring (83 mm) and autumn (55 mm), and the abrupt change of annual precipitation occurred in 1979. The climate change in the forestry region was more significant compared with those in Northeast China, North China and Northwest China, and it became more significant along with the increasing altitude of station.
