为探寻适合在红壤侵蚀区应用和推广的桉树经营模式，对红壤侵蚀区的多种桉树营林措施进行了调查和研究。结果表明：炼山有利于桉树初期的生长，但2年后，采取不炼山处理的桉树林地，桉树胸径和树高生长速度开始超过炼山处理的桉树林地，而采取全面清除植被处理的桉树林地，桉树胸径和树高的生长速度始终最慢；采取前埂后竹节沟的水保措施较不采取水保措施更有利于桉树的生长；夏季劈草对桉树生长最为有利，秋季次之，春季再次之，然后是冬季劈草和不劈草处理，且春季和秋季劈草效果差距不大，冬季劈草和不劈草无显著差异。

In order to find a management model of Eucalyptus spp.which is suitable to apply and popularize in ero-ded red soil region,afforestation measures for Eucalyptus spp.in eroded red soil region were investigated.Result shows that:controlled burning is conductive to early growth for Eucalyptus spp.,but two years later,the rate of DBH & height growth of Eucalyptus spp.forest without burning exceed that treated with controlled burning. Growth rate of diameter &height of Eucalyptus spp.forest with complete removal of vegetation are always the slo-west;Eucalyptus spp.forest taking water conservation measures with ridge in front and bamboo joint drain in back is more conductive for growth of Eucalyptus spp.than that without taking water conservation measures;herb-chopping in summer is the most favorable for growth of Eucalyptus spp.,followed by autumn,spring,winter, without herb-chopping.Herb-chopping in Autumn & Spring have little differences.Herb-chopping in winter and without herb-chopping have no significant difference.
