通过对暖温带地区两种典型人工针叶林生态系统内树干茎流和穿透雨的收集，对其中N、P、K、Ca、Mg、S和A1等7种元素进行了测定。研究发现这些养分元素在树干茎流和穿透雨中的含量在年内有明显的时间动态变化，这些变化主要受元素在水分中的含量和它们在植物生命活动中的活跃程度等影响，甚至在不同的针叶林生态系统之间都有一定的差异，其中表现最为明显的是N、K和S。 Seven kinds of elements, N, P, K, Ca, Mg, S and Al, were measured by collecting stem-stem flow and through-rain in two typical artificial coniferous forest ecosystems in warm temperate regions. The results showed that the contents of these nutrient elements in stem-flow and through-the-rain varied significantly during the year. These changes were mainly due to the content of elements in water and their activity in plant life, There is a certain difference between the coniferous forest ecosystems, of which the most obvious are N, K and S.
