会同杉木林、阔叶林集水区水化学动态的研究

Abstract

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．

Key words: Precipitation, Throughfall, Stemflow, Runoff, Water chemistry
