摘要: 为了更好地了解北暖温带落叶阔叶林凋落物养分特征及土壤肥力的状况,本研究在天津八仙山国家级自然保护区阳坡、山脊和阴坡3种典型立地条件下分别设置1 hm2样地,进行了每木调查并分析了凋落物养分特征及土壤肥力。结果发现:在3个样地中阳坡样地树木个体数和物种丰富度均最大,而个体数最小的是山脊样地,物种丰富度最小的是阴坡样地。立木材积则以山脊样地为最大,阳坡样地较小,阴坡样地最小。3个样地阳坡样地凋落物蓄积量(37.21 t·hm-2)显著大于山脊样地(26.79 t·hm-2)和阴坡样地(23.87 t·hm-2)。3个样地中阳坡样地凋落物碳、氮含量最高,而其土壤碳、氮含量最低。凋落物8种矿质元素(Ca、K、Fe、Mg、Na、Mn、Zn、Cu)总含量:阳坡样地 > 山脊样地 > 阴坡样地。通过因子分析对18个土壤肥力指标进行综合评价,发现:山脊样地(0.350)> 阴坡样地(0.091)> 阳坡样地(-0.491),说明3个样地中山脊样地土壤肥力较好,阴坡样地次之,阳坡样地较差。

Abstract: Deciduous broad-leaved forest is one of the vegetation types in the northern hemisphere, however, warm temperate deciduous broad-leaved forest is the most typical in North China. Our objective was to better study the characteristics of forest floor nutrient and soil fertility quality in deciduous broad-leaved forest of north warm temperate. We carried out plant census, and compared forest floor nutrient and soil physicochemical properties in shady slope plot, ridge plot, and sunny slope plot in Baxian Mountain National Nature Reserve. The results showed individuals was most in sunny slope plot and least in ridge plot, and species richness was most in sunny slope plot and least in shady slope plot. Standing tree volume was highest in ridge plot, and lowest in the shady plot. The amount of forest floor accumulation was significantly higher in sunny slope plot than in ridge plot and shady slope plot. In three plots, soil C and N content were lowest and forest floor C and N content were highest in sunny slope plot. The content of mineral elements:sunny slope plot > ridge plot > shady slope plot. This is the reason that The integrated soil fertility assessment scores for ridge plot, shady slope plot, and sunny slope plot were, in a descending order, 0.350, 0.091, -0.491, through factor analysis.

Key words: deciduous broad-leaved forest, sites condition, forest floor nutrients, soil fertility assessment
