坡地侵蚀红壤垦种绿化后 ,随垦种年限、红壤熟化程度的提高 ,红壤的肥力状况得到了显著改善 ,主要表现为 :水稳性团聚体数量增加 ,土壤养分含量提高 ,土壤通气性改善 ,土壤通透库容增加 ,能有效调节和控制水土流失状况 ,地表径流量和泥沙流失量大幅度降低 ,同时在各种利用方式对水土流失控制和红壤肥力状况改善的影响方面 ,林地比草地的调节作用强 ,阔叶林的作用比针叶林大。 With the increase of reclamation years and red soil maturation, the fertility status of red soils has been significantly improved. The main manifestations are as follows: the number of water-stable aggregates increased, the content of soil nutrients increased, the soil aeration improved, Soil storage capacity increased, which can effectively regulate and control the status of soil and water loss, surface runoff and sediment loss decreased significantly. At the same time, the effects of various utilization modes on soil erosion control and red soil fertility improvement, Strong regulation, the role of broadleaf forest coniferous forest larger.
