| 选择无瓣海桑、秋茄、白骨壤、木榄、桐花和拉关木6个红树林树种，在粤东沿海沙质滩涂地带进行造林试验。结果表明：（1）涨退潮风浪大的流动沙质滩涂不适宜种植红树林，避风、涨退潮海浪较小、沙土流动较缓慢的沙质滩涂可以成功造林；（2）种植后14个月，6个红树林树种造林存活率排序为白骨壤（31%）>拉关木（28%）>无瓣海桑（25%）>秋茄（22%）>桐花（18%）>木榄（14%），平均保存率为23%；（3）在风浪较小、沙土流动较缓慢的沙质滩涂营造红树林，可选择无瓣海桑、白骨壤和拉关木3个树种。 |

| Abstract: |
| The afforestation test of mangrove species, including Sonneratia apetala, Kandelia candel, Aricennia marina, Bruguiera gymnoihiza, Aegiceras corniculatum and Laguncularia racemosa were carried out in sandy beaches of eastern Guangdong. The results were as follows:The mangrove species were not suitable for flowing sandy beaches with huge tide waves. The lee and tardy sandy beaches with less tide waves could be suitable for afforestation. The survival rate of six mangrove species after 14 months of planting was Aricennia marina (31%) > L. racemosa(28%) >S. apetala (25%) > K. candel (22%) > Aegiceras corniculatum (18%) > B. gymnoihiza (14%), and the average survival rate was 23%. Aricennia marina, L. racemosa and S. apetala were suitable for growing in the lee and tardy sandy beaches with less tide waves. |
