人工林的育林方向和育林体系

本文根据我国人工林长期发展实践经验和“七五”“八五”期间针对我国人工林发展中存在问题所做的科技攻关成果进行归纳总结,为人工林的持续经营提供科技支撑。主要内容包括人工林培育上的6个方向(或目标),即定向、速生、丰产、稳定、优质和高效,以及按生态系统管理要求提出的人工林育林体系上的5个控制:遗传控制、立地控制、密度控制、植被控制和地力控制。按照上述6个方向和5个控制在人工林培育上的实施,人工林的长期生产力将会得以保持,人工林多功能培育效果也得以实现。

Targets of the Silviculture System of Plantation Forestry

The main purpose of this paper is to summarize the practical experiences in the long-term development of plantations and the scientific and technological achievements in response to the problems in plantation forestry during the period of 7th and 8th“Five-Year Plan”in China,in order to provide technical support for the sustainable management of plantations.6 targets were proposed for plantation cultivation,they are specific orientation,fast-growth,high-yield,high stability,high quality and high efficiency,and 5 controls for the silviculture system of plantation forestry based on ecosystem management requirements,they are genetic control,site control,density control,vegetation control and site productivity control.The 6 targets and the 5 controls can be applied in plantation cultivation to ensure the long-term productivity of plantations and the multiple benefits of plantations.
