文章选取四川省中西部和云南省北部山地针叶林林区的55个气象站点数据,分析了山地针叶林林区的气候变化特征。结果表明：1959—2014年,四川省中西部和云南省北部山地针叶林林区的年平均气温升高了约0.9℃,温度变化达0.168℃/10a,升温突变出现在2001年;年平均最低气温升高趋势更为显著,其气温变率达到了0.232℃/10a;四季气温均有所升高,其中冬季增温趋势最为明显,增温幅度达到了1.42℃;年降水变化无明显趋势,主要呈现年际和年代际震荡,未发生降水突变,春季降水增加而夏、秋两季降水减少,春季降水增量为3.95mm/10a。
英文摘要：
Based on the meteorological data collected at 55 weather stations in the forestry region in Midwest of Sichuan and north of Yunnan province, the climate change characteristics of mountainous region coniferous forest was analyzed. The results showed that the annual mean temperature in research region increased about 0.9℃ from 1959 to 2014, the air temperature variation was 0.168℃/ 10a, the abrupt change of annual temperature, occurred in 2001. The annual minimum temperature increased more significant with 0.232℃/10a of increment. The air temperature increased at all seasons,and in winter the air temperature increased more significant which had increased about 1.42℃. Meanwhile, the annual precipitation in the forestry region had no significant change, it shocked by the interannual change and intergeneration change and had no abrupt change. The precipitation increased in spring which increment was 3.95mm/10a, and decreased in summer and autumn.
