摘要
红树林为热带和亚热带海岸潮间带特有的植被类型 ,但因人为的破坏 ,我国红树林面积和资源锐减 ,现有红树林湿地中不少处于退化状态 ,开展红树林湿地生态恢复具有重要意义。在福建泉州湾红树林湿地开展了不同滩涂立地、造林方式、栽植不同密度下桐花树、秋茄的生态恢复试验 ,进行了各种造林方法的经济投入分析。结果表明 ,在海岸湿地进行植被恢复和造林地规划时 ,应重视滩涂潮汐浸淹深度的影响 ,尽量选择浅滩地、中滩地营造红树林。桐花树移植天然小苗 ,秋茄采用胚轴插植方法造林 ,成活率达 83%以上。造林初植密度以 0 .5m× 1.0m适当密植为宜。红树人工林通过消浪、促淤、降低风速等作用达到了保护海岸的目的。
Mangrove is the special vegetational form between coasts and tides in tropical zone and subtropical zone. With the destruction of human impact, the areas and resources of mangrove were decreased abruptly in our motherland. Parts of existed mangrove wetlands are in the status of deterioration. Therefore, it is important significance in ecological restoration of mangrove wetlands. The paper studied artificial ecological restoration of mangrove wetlands in Quanzhou bay by selecting different beach sites, afforesting patterns and planting Aegiceras corniculatum and Kandelia candel under different density, then analyzed the investment costs of each afforestation method of Aegiceras corniculatum and Kandelia candel . The result showed that shallow or medium beach must be elected when we carry out vegetation renewal and cultural planning, with the effect of tide on beach. The survive rate is beyond 83% for Aegiceras corniculatum by transplanting with natural small seedlings and Kandelia candel by planting with hypocotyls. The space of initial plantation should be properly close (0.5 m×1.0 m). Mangrove plantation effectively protects coast seashore in attenuating waves,promoting sedimentation and against strong wind.
