长白山阔叶红松林近22年的气候动态

Climatic dynamics of broadleaved Korean pine forest in Changbai Mountain during the last 22 Years.

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.

Broad-leaved Korean pine（Pinus koraiensis） forest in Changbai Mountain is one of the typical temperate forest ecosystems. Its long term climatic dynamics is important for global change research. Some climatic factors, such as radiation factor, thermal factor, moisture factors, wind velocity and wind direction, were analyzed with the meteorological data recorded by the Opened Research Station of Changbai Mountain Forest Ecosystem, Chinese Academy of Sciences. The paper reported the mean value and the dynamic characteristics of these climatic factors in the lest 22 years.
