Properties of water chemical elements of Castanea mollissima forest in Miyun reservoir watershed
摘要
Abstract
The paper studies on the water chemical elements of Castaneamollissima forest in the Miyun reservoir watershed, Beijing. The total concentration of chemical elements in precipitation was 12.0011mg/L, and it greatly varied in the main rainfall periods. The sequence of the water chemical elements contentration in precipitation was Ca>N>K>Mg>Na>P>Fe>Zn>Cu>Mn. The chemical elements of through-fall and stem-flow varied in same way, most of the chemical elements concentration were increased. Through-fall and stem-flow total chemical element concentration was 20.6135mg/L and 73.3235mg/L，respectively, they increased 8.1624mg/L and 62.3124mg/L than those in precipitation, respectively.关键词
