摘要
森林凋落物是森林生产力的重要组成部分,辽西建平付山地区试验研究,在凋落物现存量、林下凋落物层的积累量和持水量等方面均表现为油松蒙古栎混交林>油松纯林。较高的凋落物量有利于提高土壤肥力、保持水土,对提高林分稳定性,促进林分生长有明显的改善或提高作用。
Forest litter is the important part of forest resources. The status of Fusan is in the west of Liaoning province. In the study of litter standing crop,litter layer accumulative and water holding capacity,Quercus mongolica and Pinus koraiensis〉Pinus koraiensis. The plant species and individuals in mix forest were more abundant and complicated than that in the pure forest. Forests were conducive to improving soil fertility,conserving soil and water,improving forest stability and growth.
