摘要: 基于田间试验和室内分析数据,分析了不同管理方式对人工林生态系统地力和持续发展的影响.结果表明,幼林期间种豆科牧草等农作物、营造混交林、针叶纯林间伐后引进阔叶树等生物途径以及改变整地方式、合理施肥等工程措施都有利于地力的恢复和林分生产力的提高.

Abstract: Based on field and laboratiory experiments,the effect of different management approaches on site fertility and sustainability of plantation ecosystems such as Cunninghamia lanceolata and Pinus massoniana is analysed.The results show that some biopathways such as intercropping with leguminous grass,silviculture of mixed plantations, introducing broadleaved tree species after thinning,and some engineering measures such as application of fertilizers and changing methods of site preparation can be helpful to the recovery of soil fertility and the increase of productivity of pure conifer forest.
