| 摘 要： | 在东江中上游特定的气候条件和特定的紫色红壤上，开展了水土保持林树种选择试验。初步选择出具有固氮改土能力的肯氏相思、绢毛相思和大叶相思作为严重水土流失紫色红壤地区的先锋树种；选择了慢生的伴生树种红锥和海南红豆；在辅以人工施肥的情况下，选择了速生树种桃金娘科的尾叶桉和红胶木。在先锋、速生和慢生树种，以及乔、灌、草相互结合的技术措施指导下，营造的水土保持示范林取得了较为理想的保持水土效果。

| Abstract: | Soil erosion in the purple red soil area of Dongjiang,in the east of Guangdong is serious. It is not easy to select the proper tree species for forestation. The objective of this trial is to find some suitable tree species for establishment of ecological forest and vegetation restoration. After 4 years experiment, it was found that Acacia cunninghamii, A. holosericea and A. auriculiformis were the 3 best pioneer species because of their N fixing capability. Eucalyptus urophylla and Tristania conferta were also suitable for vegetation recovery if fertilizer is used. As the indigenous species, Castanopsis hystrix and Ormosia pinnata were the best. Under such tough condition, It would be better to mix pioneer tree species with indigenous ones, shrub and grass together for forestation. |
