摘要
为了研究内蒙古大兴安岭林区的气候特征,通过采用线性回归方程以及线性趋势的方法,研究了内蒙古大兴安岭中部林区—根河1981—2010年的气象监测数据,分析了温度、降水、湿度、日照时数、风速等气象要素的变化规律以及与全球气候变化的关系。结果表明:在全球气候变暖的趋势下,根河林区呈气温升高,降水量减少,日照时数增加的趋势,该区各气象要素与全球气候变化存在一定的对应关系;通过分析得出林区近30年气温的增长趋势(0.42℃/10年)明显高于全国平均水平,气温上升趋势较为显著。
In order to study climate characteristics of the Greater Khingan Mountains, by using a linear regression equation and the linear trend method, the author studied the on-site monitoring data of Genhe of the Greater Khingan Mountains in Inner Mongolia from 1981 to 2010, analyzed the changing rules of temperature, precipitation, humidity, sunshine hours, wind velocity and other meteorological factors in the region and their relationship with the global climate change. Results showed that, under the trend of global warming, Genhe of the central Greater Khingan Mountains was keeping with the trend of temperature increase, precipitation decrease and the increase of sunshine hours. The meteorological factors had some corresponding relationships with global climate change. The results also indicated that the surface temperature growing trend （0.42℃ per 10 years） in the past 30 years in Genhe was much higher than the national average, and the temperature increasing trend was obvious.
