通过对20多年生人工诱导的阔叶红松林系列生态效益调查,结果表明,混交林与纯林相比,枯落叶贮量、土壤持水能力、养分含量及分解速率、蚯蚓数量、林下草灌植物和土壤中细根生物量等,明显高于红松纯林;混交林对改善土壤理化性质,增强林木自我施肥机制及贮水保土能力等产生了明显的效果,并对红松主要病害起到了明显的抑制作用,它将成为我国东北东部山地生态协调的理想森林群落类型。
The ecological benefits of 20-year-old man-made broad-leaved Korean pine forests were studied. The results showed that compared with pure forests, the litter reserves, soil water holding capacity, nutrient content and decomposition rate, the number of earthworms, The fine root biomass in soil was significantly higher than pure Pinus koraiensis plantation. The mixed plantation had obvious effect on improving soil physical and chemical properties, enhancing the self-fertilization mechanism of forest tree and water storage and soil conservation ability, Obvious inhibitory effect, it will become the ideal type of mountain forest ecological coordination in the eastern part of northeast China.
