本文就寒温带大兴安岭林区兴安落叶松原始林生态系统降水输入总养分含量、大量元素和微量元素的养分含量占总养分含量的比值、降水输入养分含量月际变化和年内分配等进行了分析。结果表明 :兴安落叶松原始林区降水输入的大量元素低于其它几个研究地区。微量元素含量趋平均水平。降水输入养分月际变化最大者是 Ca元素。全年降水输入养分集中在生长季。
In this paper, the total input of precipitation, the ratio of nutrient content of total nutrients and total nutrients to total nutrient content, the monthly variation of input nutrients in precipitation and annual distribution of Larix gmelinii forest ecosystem in the cold temperate Daxing’an Mountains were analyzed. The results showed that a large number of elements input into precipitation in virgin forest of Larix gmelinii were lower than those in several other studied areas. Trace elements average level. Precipitation input nutrients, the largest change in the month is Ca element. Annual precipitation input nutrients concentrated in the growing season.
