摘要(Abstract)：

以福建柏、木荷纯林为对照,对福建柏木荷混交林的经营密度和混交比例进行试验分析。研究结果表明:福建柏木荷混交造林是一种较好的混交组合。从经营密度分析10 a生混交林中福建柏平均胸径生长量从大到小依次表现为B > A > C,造林密度2 500株·hm^-2有利于福建柏胸径生长;从平均树高生长量分析,混交林中福建柏从大到小依次顺序为A > B > C。从混交比例分析福建柏的平均树高从大到小依次为B8M1 > B2M1 > B1M1 > B1MO,无论是何种的混交比例,混交林中福建柏的平均树高、平均胸径均大于福建柏纯林。福建柏林分蓄积B8M1与B1M1比差异达到极显著,B8M1与B2M1、B1MO比达到显著差异水平,B2M1、B1MO与B1M1 B0M1比达到显著差异水平。福建柏木荷混交对福建柏林分蓄积有积极作用,以B8M1为好。福建柏木荷混交8:1插花混交、2:1带状混交是可以推广的福建柏木荷混交组合。
In this paper,taking Fokienia hodginsii and Schima supeaba pure forests as a control,experimental analysis is made of the mixed density and ratio of Fokienia hodginsii and Schima supeaba mixed forest. The results have shown that mixed Fokienia hodginsii and Schima supeaba plantation is a better mixed combination. Analysis from the operating density B > A > C,afforestation density of 2 500 trees per hectare is favourable to Fokienia hodginsii DBH growth; in 10-year-old mixed forest from an average tree height growth analysis,Fokienia hodginsii displays a decreasing order of A > B > C. Fokienia hodginsii average height sequence from the mixed ratio analysis is B8M1 > B2M1 > B1M1 > B1MO. It is indicated that average tree height and average DBH of Fokienia hoginsii in mixed forest are greater than those in Fokienia hodginsii pure forest.
