摘要
林分改造在优化群落结构、改善林分质量以及提高生态功能等方面具有重要作用,是建立高功能效益生态公益林的重要举措。文章对中山市五桂山以大叶相思、马占相思以及马尾松林为主的混交林分的枯落物和土壤持水功能进行研究。结果表明,混交林分中枯落物持水量的大小顺序为:马尾松林>马占相思林>大叶相思林;土壤持水量大小为:大叶相思林>马占相思林>马尾松林。
Forest rehabilitation plays an important part in bettering plant community structure, improving the quality of forest stand and ecological functions, and establishing ecological public-welfare forests with high functional benefits. The paper made a research on the water-holding capacity of the litter layers and soil in the mingled forest stand in Wugui Mountain of Zhongshan, where the forest is primarily occupied by Acacia auriculiformis, Acacia mangium and Pinas massoniana. Results showed that the order of the water-holding capability of litter layer is Pinas massoniana〉 Acacia auriculaeformis〉 A. mangium, and the order for soil is Pinas massoniana〉 A. mangium〉 Acacia auriculaeformis.
