摘 要:对生态防护林、薪炭林、用材林、经济林四个林种的特性进行了分析,分别提出了它们对树种的要求。根据树木对光照、水分、温度、土壤的不同要求的生物学特性,研究树种混交原理及混交技术,主要包括混交林的树种配置、混交比例、混交方式。并以杉松、杉桤、杉檫混交为例,研究树木混交的丰产效果以及产生丰产效果的机理。The study and analysis based on the characteristics of the following four: forest ecological prevention forest, firewood forest, timber stand and commercial forest. The demand of the those forests also was pointed out in the paper. The theory and technology of mixed plant were studied on the different ecological characters such as light, water and soil. The main mixed plant technology included the species arrangement, proportion and method of the mixed forest. The effect and mechanism of high-yield were studied by the example of mix forests Cunninghamia,lanceolota added pinus,Cunninghamia.lanocolata added Alus,cremastogyne,and Cunninghamia,lanceolota added Sassagai,tzumu.
