大气降水经过茂密的树木枝叶后,其化学成分含量会发生改变,本文通过于2011年4、5月份在桂林理工大学校园内接收未经植被淋滤的普通雨水和经过铁树、桂花树、竹子3种树木枝叶淋滤的雨水,测定其K＋、Na＋、Mg＋、Ca2＋、SO24-、Cl-、PO34-和TN的含量,分析其基本特征和变化规律。大气降水在经过以上3种树木枝叶淋滤后,其总氮含量及各种离子含量和未经树木淋滤的普通雨水相比都是增加的。由于各种综合因素影响,其变化规律呈多样性。

The content of nitrogen and conventional ion in atmospheric precipitation will change after leaching through dense tree branches.This study collected the atmospheric precipitations with and without leaching through the branches of iron tree,acanthus tree or bamboo tree in May and April 2011 on the campus of Guilin University of Technology(GUT).K+,Na+,Mg+,Ca2+,SO2-4,Cl-,PO3-4 ion and nitrogen in these waters were measured and their basic characteristics and changing rules were analyzed.After leached by the aforementioned trees,the total nitrogen and various kinds of ion increased compared with precipitation not leached.The changing rules are diversified due to various factors.
