摘　　要：通过对无瓣海桑人工林进行修枝,并在林下种植木榄,在林区内挖掘沟渠网,同时根据生态位理论,采用原位修复、异位修复和中度干扰等技术措施,人工养殖沙蚕、星虫、贝类、虾蟹和鱼类等水生经济动物,结果显示实验区水生经济动物的存活率和个体的平均重量明显高于对照区,说明该生态养殖方式能在不破坏已经恢复的无瓣海桑人工林前提下,有效降低无瓣海桑某些生物学特性对水生经济动物的影响,实现将无瓣海桑人工林沼泽作为鱼虾蟹养殖业基地.Applying strategies of pruning for the Sonneratia apetala artificial plantation, planting Bruguiear gymnorrhiza at the lower level of the woods and digging the network of ditches, supplemented by Niche Theory, with technical measures such as in-situ remediation, ex-situ remediation and intermediate disturbance, the aquatic economic animals such as nereids, sipunculids, shellfish, shrimps and crabs and other fish are bred. The result suggests that the livability and average weight of the animals in experimental plot apparently is higher than that of the control plot. The data demonstrate our ecological breeding strategies can effectively reduce the negative effect of some bio-characteristics of Sonneratia apetala on the premise of no destruction to the recuperatived artificial plantation. It＇s proved there will be a possibility to make the Sonneratia apetala plantation to be a breeding base of fish and shrimps.
