本文采用定位研究系统测定分析方法,对我国南方山地重要的混农林业生态系统——杉木-黄连林药复合生态系统进行了研究.结果表明:①林药人工复合生态系统通过调节、自控和多层次地利用光能以及系统的良性循环,光能利用率和系统的生产力有显著提高.林药复合生态系统中的林木生物最比纯林高2倍以上,年生产量高3倍多,年生产总量比纯林高4倍;②林药复合生态系统能够创造一个优于自然生态系统和传统搭棚栽连的环境条件,使杉木、黄连均能适生,为遗传特性的稳定创造了条件,从而品质优良、产量增加.黄连的药用成份含量达到传统搭棚栽连的99%以上;③杉木-黄连林药复合生态系统1ha节省木材52.5m3以上,省工28.7%,纯收益增加62.4%,劳动生产率提高30.3%.本文还针对林药复合生态系统的特点,探讨了杉木-黄连复合生态系统构建的技术关键和步骤.
In this paper, we used the method of location analysis system to study the complex ecosystem of Chinese fir-coptis chinensis forest, an important agro-forestry ecosystem in the mountainous areas of southern China. The results showed that: (1) The level of utilization of light energy and the virtuous circle of the system have significantly improved the utilization rate of light energy and the productivity of the system. The forest organism in the composite forest ecosystem is 2 times more than the pure forest and has an annual output of more than 3 times. The total amount is 4 times higher than that of the pure forest; ② The composite forest-medicinal ecosystem can create a better environmental condition than the natural ecosystem and the traditional scaffolding plantation, , Thus the quality is good and the yield is increased.The content of the medicinal ingredient of Coptis chinensis reaches more than 99% of that of the traditional scaffolding plantation; ③The 1ha of Coptis-Coptis Linyi compound ecosystem saves more than 52.5m3 wood, saves 28.7% of the labor and the net income increases by 62.4 %, Productivity increased by 30.3% .This paper also aimed at the characteristics of forest medicine compound ecosystem, explored the Chinese fir - Coptis complex construction of the key technologies and steps.
