摘　　要：通过对红松、落叶松分别与紫椴混交的林型进行综合评价研究,结果表明:宽带状混交的林分生长表现优于窄带状混交的林分,混交林生物量大于纯林,针阔混交林综合效益明显;混交林物种丰富度的种类、数量都远远高于纯林;混交林中物种多样性复杂,土壤营养含量丰富,能加快枯落叶的分解速度,提高土壤肥力,改善土壤结构,加速营养元素的释放量。Forest types of Pinus koraiensis and Larixspp.which are respectively mixed with Ti1ia amurensis were studied comprehensively.Result shows that:the growth performance of broad-strip mixed-forest is optimal than that of narrow-strip mixed-forest;biomass of mixed forest is more than that of pure forest;the comprehensive benefits of broadleaved-coniferous mixed forest are significant.Species,numbers of species richness are much higher than that of the pure forest.In mixed forest,species diversity is complex,the soil nutrient is rich,broadleaved trees in the mixed forest can speed up the rate of decomposition of leaf litter;mixed forest can improve soil fertility,improve soil structure,and accelerate the release of nutrients.
