| 摘 要： | 人工林资源是森林资源的重要组成部分。我国人工林总体质量不高，普遍存在着生长量低、保存率低以及生产力低下等问题。文中在对人工林生产力研究的历史背景进行回顾的基础上，概述立地条件、初植密度、间伐措施、林地清理、连栽代数、施肥等方面对人工林生产力产生的影响，提出了促进我国人工林生产力维持关键技术体系研究的建议，即加强人工林生产力长期性、系统性、多目的性的研究。

| Abstract: | Plantation resource is an important component of forest resources. Overall plantation quality is not high in China, and the problems like low growth, low preserving rate and low productivity are commonly observed. This paper reviewed the historical background of the research on plantation productivity, described factors affecting plantation productivity including site conditions, initial planting density, thinning measures, ground clearance, and continuous planted algebra and fertilization. Finally, it was proposed to carry out key technology system research on plantation productivity maintenance and strengthen the research on the long-termness, systematic development and multi-purpose of planatation productivity. |
