摘要: 对杉木林、阔叶林集水区的降水、穿透水、树干茎流水、地表径流水和地下水中化学元素的动态特征进行研究的结果表明,大气降水中元素含量与降水形态、降雨量大小有关;穿透水和树干茎流水中绝大多数元素含量增加2—24倍。杉木林的地表径流水中K、Ca、Mg、Fe、Cu元素含量高于穿透水;地下水中绝大多数元素含量低于穿透水和地表径流水。该项研究,可为森林生态系统物质循环和区域环境质量评价提供科学依据。

Abstract: The dynamics of chemical elements in precipitation,throughfall,stemflow,surface runoff and underground runoff have been studied.The results showed that element con-tents in precipitation associated with the amount and its characteristics of a rainfall.Most element contents in throughfall and stemflow increased 2 to 24 times than in pre-cipitation.In Chinese fir plantations,the amount of most elements in surface runoff,such as K,Ca,Mg,Fe,and Cu,were larger than those in throughfall,while most element con-tents in underground runoff were lower than those in throughfall and surface runoff.The results can benefit the physical cycle in forest ecosystem and the large—scale evaluation of environment quality.
