Climatic Change Characteristics and Its Impaction in Wutai Mountain
Based on the daily temperature(including average,lowest and highest temperature),precipita-tion and sunshine duration data of Wutai Mountain from 1998 to 2019,the multiple time scale variation charac-teristics of temperature,moisture and radiation were studied.Meanwhile,we also analyzed its impaction on tourism development.The results showed that:(1)There was an increasing trend in temperature at a rate of 0.1 ℃/10 a.The trend of the annual average minimum temperature was the most evident,and the average mini-mum temperature was increased most in spring;(2)The annual precipitation presented a statistically significant increasing trend at a rate of 124.66 mm/10 a,and the annual precipitation days increased significantly at a rate of 17.44 d/10 a in Wutai Mountain.Summer Precipitation was about 60％of the annual total amount and played a major role in Wutai Mountain.The seasonal precipitation and precipitation days both increased,and in summer occurred the remarkable change rate.The contribution of light and moderate rainfall to the annual precipitation was 67％;(3)All precipitation indices on different grades increased,and the amount of heavy rain and the number of light rain both had a remarkable upward trend;(4)The annual sunshine duration had significant de-creasing trend.During four different seasonal sunshine durations,the sunshine duration in spring was the most.The sunshine durations in four seasons all decreased,and the changing trend of the summer,autumn and winter sunshine duration showed a significant decreasing trend.
