摘　　要：在福建省沙县进行不同地下水位水湿地营造江南桤木试验,结果表明:在水湿地可以营造江南桤木,且地下水位较低(40~60 cm)的林分生长状况较好,造林成活率94.4%,造林保存率93.8%,10年生平均胸径10.8 cm,平均树高10.8 m,立木材积148.5681 m^3/hm^2,平均木生物量17.97 kg,乔木层生物量52.005 t/hm^2。An experiment on constructing Alnus trabeculosa forest in wetland with different underground water level was car-ried out in Sha County of Fujian, the results showed that Alnus trabeculosa can be established in the wetland, furthermore the stand growth was better when the underground water level was low （40 -60 cm） with survival rate of 94.4% and afforesta-tion preservation rate of 93. 8% , the average DBH of 10 years-old plant was 10. 8 cm, the average height was 10. 8 m, standing timber volume was 148. 5681 m^3/hm^2 , the average biomass was 17. 97 kg/plant, and the tree layer biomass was 52.005 t/hm^2.
