Abstract
[ Objective] The aim was to study the variation characteristics of temperature and precipitation in Benxi Manchu Autonomous County of Liaoning in recent 50 years. [ Method] By using meteorological observational data in Benxi Manchu Autonomous County during 1961 -2010, and the conventional mathematical statistics method was adopted to analyze the variation characteristics of smaller scale temperature, precipitation decadal climate of this county. [ Result] The annual average temperature in Benxi Manchu Autonomous County of Iiaoning was 7.0 ℃ during 1961 -2010, annual average temperature over the years increased obviously with the year, and climate trend rate was 0. 517 ℃/10 a, moreover, the trend increased by 2.6 ℃ in recent 50 years; in recent 10 years the trend increased by 2.0 ℃ than 1960s, however, in recent 20 years, the average temperature had not any increasing trend; temperature of spring, summer, autumn and winter had increasing trend to different degree, especially in winter. The larger the variability of annual precipitation, seasonal precipitation, the poor the stability; average precipitation over the years was 781 mm, annual precipitation showed decreasing trend, furthermore, precipitation in spring and winter was more than summer and winter. [Conclusion] The study provided climatic background for large scale climatic analysis, and also provided basis for understanding and grasping variation characteristics of local climate and disaster prevention.关键词
