摘要
分析了杉阔混交林中杉木与 1 2个主要混交树种分别在不同资源空间 (土壤物理与化学营养 )中的种间竞争情况。结果表明 :在同一资源空间中 ,杉木与混交树种的竞争结局依树种不同而异。杉木与同一混交树种在不同资源空间中具有不同的竞争结局。建议在不同立地条件或采用不同混交树种时杉木与混交树种的混交比例应不同。
Interspecific competition between Chinese Fir and its 12 main mixed species in different resource space(physical and chemical nutrient of soil)was studied. The results showed that the stage of interspecific competition between Chinese Fir and its mixed species was different according to different species in the same resource space. In different resource space, the stage of interspecific competition between Chinese Fir and a certain species was different.It suggested that the mixed ratio between Chinese Fir and its mixed species should be different according to different groups of site type and species.
