通过对北方土石山区不同木本植物的径流小区进行土壤物理性状的测定和径流量、侵蚀量的观测,分别在汛期降雨量、不同降雨强度和前期降雨条件下,揭示不同木本植物径流小区所产生的径流量和侵蚀量的变化规律,为临朐县乃至相同类型地区的坡面综合治理提供理论依据和实践指导。结果表明:土壤物理性状、土壤含水量、土壤饱和贮水量及土壤渗透速度以葛藤林地为最好,其次是桑树、胡枝子、花椒、李树林地,种植花生小区为最差。分析降雨量、降雨强度、前期降雨对灌木径流小区径流量和侵蚀量的影响,表明不同灌木林的蓄水、保土效益皆以葛藤林地为最好,其次为桑树、胡枝子、花椒、李树林地,种植花生水土流失最严重。
By measuring soil physical properties and runoff and erosion of runoff plots of different woody plants in the northern mountainous area, the authors found that different flowering communities of woody plants under rainfall, rainfall intensity and rainfall in the rainy season The variation of runoff and erosion caused by this model can provide theoretical basis and practical guidance for the comprehensive management of slope in Linqu County and even the same type of area. The results showed that soil physical properties, soil water content, soil saturated water storage capacity and soil infiltration rate were the best in Kudo for woodland, followed by mulberry, Lespedeza, Chinese prickly ash and plum woodland. The effects of rainfall, rainfall intensity and pre-rainfall on the runoff and erosion of shrub runoff community were analyzed. The results showed that the storage and soil conservation benefits of different shrubbery were the best in the field of kudzu vine, followed by mulberry, Lespedeza, Chinese prickly ash, The most serious soil erosion is peanut cultivation.
