长白山阔叶红松林作为典型的温带森林生态系统,其长期的气候动态状况对研究全球变化具有重要的意义。本文采用中国科学院长白山森林生态系统定位站气象观测场1982~2003年的地面常规气象观测资料,对长白山阔叶红松林的光能因子(包括年日照时数、年日照百分率)、热量因子(包括年平均气温、1月、7月月平均气温、年极端最高、最低气温、年积温)、水分因子(包括年总降水量、年最大雪深、相对湿度、年总蒸发量)、以及年平均风速与风向等气候因子进行了分析,从而得出这些因子22年的平均值及其动态变化趋势,进而为相关领域的研究提供基础资料。
As a typical temperate forest ecosystem, the long-term climate dynamics of Changbai Mountain broad-leaved Korean pine forests is of great significance for studying global changes. In this paper, the meteorological observational data of Changbai Mountain Forest Ecosystem Positioning Station of Chinese Academy of Sciences from 1982 to 2003 were used to analyze the light energy factors (including annual sunshine hours and annual sunshine percentage), the thermal factors (including Annual average temperature, monthly mean temperature in January and July, annual extreme maximum, minimum temperature, annual accumulated temperature), water factor (including annual total precipitation, annual maximum snow depth, relative humidity, annual total evaporation), and annual average Wind speed and wind direction and other climate factors were analyzed, and the average of these factors for 22 years and its dynamic trends, and thus provide the basis for the study of related fields.
