杉木速生丰产的研究体系

A Research System for a Fast-Growing and High-Yield Plantation of Chinese Fir

在总结过去已形成的杉木速生丰产的研究体系的基础上,运用系统途径原理提出了这种新的研究体系。本研究体系将杉木生物学特性、立地条件、密度控制三大要素融为一体,使基础理论研究、应用技术研究、综合技术推广、生产实践四大结构层次一步到位,还具有信息反馈机制,有利于科技转化为生产力。结果表明,本研究体系将使杉木速生丰产研究基本达到预期的研究目的,产生了巨大的社会、生态和经济效益。

Summarizing research systems for the fast-growing and high-yield plantation of Chinese fir over the past years, this paper presents a new research system for the plantation by means of the systematic approach. The research system consists of three key factors,the biological characteristic of the species, site and density control of the plantation , which is divided into four research layers,theory, applied technique, application of the theory and techn-ique, and the practice Of culture, and has a feedback information among the factors or the layers. The result for the application of the research system to the practice showes that it nearly reaches the expected goal, and has brought about very significant social, ecological and economic benefit.
