摘    要:于2003年5月至2004年9月,在长白山自然保护区北坡垂直植被带的4种林分(阔叶红松林、红松云冷杉林、岳桦云冷杉林和岳桦林)内,利用凋落物原位减少法对凋落物分解过程中的养分动态变化进行了研究.结果表明:4种森林凋落物分解过程中C质量分数变化幅度不大,N和P质量分数都是先上升后下降;K质量分数呈逐渐降低的趋势;阔叶红松林、红松云冷杉林、岳桦云冷杉林和岳桦林凋落物的养分年释放总量依次为1380.80、1145.46、418.74和599.91kg·hm-2·a-1.

关 键 词:凋落物  养分动态  长白山

Abstract:An experiment was conducted to study the changes in soil nutrients of four types of forests in Changbai Mountains during litter decomposition by the method of in situ litterfall lessening during May 2003 and September 2004.Results showed that the content of carbon changed unobviously,the contents of nitrogen and phosphorus increased first and then decreased,and the content of kalium gradually decreased during decomposition.The total annual amounts of nutrients released by litter decomposition in broadleaved...
