| 摘要: |
| 潮间带生境特殊，红树植物移植后常因根系受损和生境变化而难以存活。为有效制定红树林保护与修复措施，本研究以白骨壤(Avicennia marina)、秋茄(Kandelia obovata)和桐花树(Aegiceras corniculatum)为对象，通过监测3种红树植物成树移植后的存活状态并结合多指标,分析其生理适应策略。结果表明:①移植3个月后，白骨壤、秋茄、桐花树的存活率分别为64.38%、52.78%、49.87%，移植17个月后分别降至47.95%、47.22%、44.35%，移植22个月后分别降至42.47%、44.44%、41.46%。其中，根系损伤和低温可能是影响存活率的重要因素。②成树移植恢复周期长，3个树种移植22个月后植株仍处于资源再分配状态。③移植点白骨壤叶片角质层厚度、上表皮厚度、C含量、K含量、干季中午水势显著低于原生境，比叶面积、Na含量、Cl含量显著高于原生境，表现为高能耗泌盐策略，防御削弱、虫害加剧；秋茄叶片P含量、Na含量显著低于原生境，多数叶片性状与原生境无显著差异，表现出较强的功能保守性；桐花树比叶面积及N、P、K、Ca、Na、Cl含量均显著低于原生境，表现为资源节约型策略。建议移植后针对不同树种采取差异化管理，白骨壤需加强水分补给与虫害防治，秋茄可采取简化管护措施，桐花树应施用磷肥，以提高红树植物成树移植的存活率和恢复效果。 |

| Abstract: |
| Mangrove plants in the intertidal zone are often difficult to survive after transplantation because of root damage and habitat change. Aim to provide a scientific basis for formulating effective measures for the protection and restoration of mangroves,this study focused on three species of mangroves:Avicennia marina,Kandelia obovata,and Aegiceras corniculatum.The survival status of the transplanted individuals of these three species was monitored,and multi-index analysis was performed to study their physiological adaptation strategies.The results are expected The main results are as follows:①Three months after transplantation,the survival rates of Avicennia marina,Kandelia obovata,and Aegiceras corniculatum were 64.38%,52.78%,and 49.87%,respectively.The rates decreased to 47.95%,47.22%,and 44.35% after 17 months and 42.47%,44.44%,and 41.46% after 22 months.Root damage and low temperature may be the main factors affecting survival.②The mature tree transplantation involved a long recovery period,and the plants of the three species remained in a state of resource reallocation 22 months after transplantation.③The transplanted plants of Avicennia marina showed significantly lower cuticle thickness,upper epidermis thickness,C and K content,and midday water potential during the dry season but significantly higher specific leaf area and Na and Cl content than native habitat individuals,reflecting a high-energy salt-secretion strategy,but with reduced defense capacity and increased insect infestation.The transplanted plants of Kandelia obovata showed significantly lower P and Na content and no significant changes in most leaf traits than native habitat individuals,demonstrating a conserved functional strategy.The transplanted plants of Aegiceras corniculatum showed significantly lower specific leaf area and significantly lower N,P,K,Ca,Na,and Cl content than native habitat individuals,adopting a resource-saving strategy.According to these findings,species-specific management measures after transplantation are recommended:Avicennia marina requires enhanced water supply and pest control;Kandelia obovata can be managed with simplified maintenance;and Aegiceras corniculatum should receive phosphorus fertilizer application.These measures can improve the survival rate and restoration effectiveness of mature mangrove transplantation. |
