通过对杉木檫树混交林与杉木纯林和檫树纯林的造林实验,在同一阳坡上三个实验区中设立600m2标准地,分别对纯林、混交林的生物量和林地土壤性状进行测定,对标准地上标准木用全重法分别树干、枝、叶和根进行乔木层生物量测定,对土壤按常规方法测定其物理性质和化学性质。研究结果表明:混交林的生物量大于纯林,对林地土壤的物理和化学性质的影响效果优于杉木纯林而劣于檫树纯林。 Based on the experiment of afforestation of the mixed plantation of Cunninghamia lanceolata and pure Chinese fir plantations and pure stand plantation, 600m2 standard plot was set up in three experimental zones on the same sunny slope. The biomass of pure forest and mixed plantation, Determination of the standard on the standard wood with full weight, respectively, trunk, branch, leaf and root tree biomass measurement, the soil by conventional methods to determine its physical and chemical properties. The results showed that the biomass of mixed forest was higher than that of pure forest, and the effect on the physical and chemical properties of forest soil was better than that of pure Chinese fir plantation and pure plantation.
