摘要: 選取西藏東南部原始林區(qū)9個典型氣象站資料,分析林區(qū)氣候變化特征。結果表明:1954—2009年,藏東南林區(qū)年平均氣溫升高0.9℃,其中冬季升溫高達1.47℃,升溫突變點出現在2001年;林區(qū)年降水量增加了185 mm,其中春、秋季節(jié)分別增加83 mm、55 mm;藏東南林區(qū)氣候趨于暖濕化;藏東南林區(qū)氣溫和降水的變化比我國東北、華北、西北等地顯著,且海拔越高越顯著。

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.
