藏东南高山松林凋落物特征研究1
Litter characteristics of Pinus densata forest in Southeast Tibet
[目的]通过探究藏东南高山松林凋落物特征,为揭示该区凋落物特征形成原因以及发挥青藏高原生态安全屏障作用提供理论依据。[方法]以藏东南针叶林优势种群高山松林作为研究对象,在藏东南地区选取 5个典型样点,测定凋落物特征变化情况。[结果]五个样点高山松林凋落物平均厚度为 10.98±1.01cm,LL、BK、DZ和BB样点凋落物厚度不同层次排序均为:未分解层＞半分解层＞腐烂层,而 DD样点凋落物则相反;五个样点凋落物平均鲜重为 7075.73±938.…查看全部>>
