黄山近50年的气候变化研究

Study on Climate Change at Huangshan Mountain in Recent 50 Years

利用1956—2005年黄山风景区光明顶气象站的气象资料,分析了近50年黄山旅游风景区气温、降水、日照时数的变化特征。结果显示,黄山风景区年均温、冬季、夏季气温均呈上升趋势,冬季增温强于夏季;降水总体趋势下降;年平均日照时数也呈总体下降趋势,表明黄山风景区气候正在趋向变暖,特别是20世纪90年代以来气温升高显著,冬季增温明显,夏季降水变化加剧。

Based on the meteorological data of Guangmingding meteorological station in Huangshan Mountain Scenic Area from 1956 to 2005,the characteristics of temperature precipitation and sunshine duration in the last 50 years were analyzed. The results showed that the annual mean temperature, winter mean temperature and simmer mean temperature were rising generally. Winters witnessed stronger wanning than summers. The precipitation showed a decreasing trend generally. The annual mean sunshine duration had a decreasing trend too. According to the analysis above, the climate in Huangshan Mountain Scenic Area was becoming warmer.Especially in the 1990＇s,temperature increase in winter became more obvious,variations of precipitation in summer was more remarkable.
