冀北山地油松蒙古栎混交林水化学特征
Precipitation Hydro-chemical Characteristic of the Mixed Forest of Pinus and Mongolicain of North Mountain of Hebei Province
摘要
Abstract
The contents of six nutrient elements（Ca,Fe,K,Mg,Mn,Zn） in through-fall,stem-flow and litter water were measured in the Pinus-Mongolicain cross-forest in mountains of north Hebei province.The results showed that：（1）Chemical elements content of atmospheric precipitation were increased to different degrees as a sequence of CaKMgFeMnZn after they were passed through the canopy layer,also a sequence of CaKMgFeZnMn was detected in stem-flow,in litter water,the elements of K and Ca had largest increase in concentration.（2）In atmospheric precipitation,variation coefficient of Zn was the highest one with its index 2.853,K and Ca were the lowest with their index 0.158 and 0.163 respectively.In through-fall,the element Fe had the highest variation coefficient as well as the element Zn in stem-flow with their index 0.692,0.594 respectively.In litter water the element had the highest variation coefficient was also Fe with its index 1.164.（3）All of the elements measured were increased in concentration after leaching,and there were more Ca,K but few Fe,Mn,Zn leached in through-fall,stem-flow and litter water.关键词
