摘要：为了解不同间伐强度经营对柳杉人工林林地的影响,分析了对照、弱度间伐、中度间伐、强度间伐后土壤理化性质的变化。结果表明,柳杉林土壤密度(0~20cm)随着间伐强度的增加而增加,土壤最大持水量、最小持水量、毛管持水量、非毛管孔隙度、毛管孔隙度、总孔隙度(0~20cm)排序均为弱度间伐>中度间伐>对照>强度间伐;柳杉林土壤全N、全P、全K、水解性N、速效P、速效K(0~20cm)变化规律均随着间伐强度的增加而降低;弱度间伐、中度间伐对柳杉林土壤干扰影响较小,并有利于提高土壤含水能力和改善土壤肥力。
An investigation on Cryptomeria fortunei plantations was conducted by analyzing the impacts of different thinning intensities on the soil physicochemical properties.The results showed that the soil density (0-20 cm)increased with the increase of thinning intensity.The order of soil maximal saturated water retention,minimum saturated water retention,capillary water retention,non-capillary porosity,capillary porosity,total porosity (0-20 cm)was low thinning management>medium thinning management>control>high thinning management.Total N,total P,total K,hydrolytic N,available P and available K in soil (0-20 cm)all decreased with the increase of thinning intensity.Low thinning management and medium thinning management had less impact on soil disturbance and helped to develop soil water capacity and soil fertility.
