| 摘 要： | 通过对小兴安岭林区云冷杉林的对比分析,探索云冷杉林演替特征及土壤变化趋势,以达到对云冷杉林的合理经营与定期监测的目的.结果表明:云冷杉林地上层土壤密度均小于下层土壤密度,土壤孔隙度、土壤水分含量均是上层大于下层.死亡云冷杉林土壤密度与生长良好的云冷杉林相比呈下降趋势,由0.75g·cm-3降至0.49g·cm-3;土壤孔隙度呈增加趋势,由70.73%增至80.77%;有机质、水解N呈上升趋势,速效钾、速效磷质量分数则呈下降趋势.生长良好的云冷杉林各种水分常数均低于严重死亡的云冷杉林,且达差异显著水平(p＜0.05).结果揭示出云冷杉生长状况变化对土壤性质的影响和云冷杉对土壤性质变化的反应.

| Abstract: | A comparative analysis of different growth status of spruce-fir forests in Xiaoxing'an Mountains was conducted.The relationships between the succession characters of spruce-fir and its soil properties were analysed in order to realize rational management and regular monitoring.Results showed that the soil bulk density of the upper layer was less than that of the subsoil,while the soil porosity and soil water content of the upper layer were more than those of the subsoil.Compared with the well-grown spruce-f... |
