摘　　要：生态受损和生态环境代价是制约中国海岛开发利用的关键问题。本研究以珠海三角岛生态修复项目为例,介绍了团粒喷播技术在生态受损海岛边坡的应用,分析了采用以豆科植物为主要喷播植物的团粒喷播技术修复海岛受损边坡的效果和固碳价值。不同时间修复效果表明,修复植物能够快速生长,对地表形成极高覆盖度,并与本土物种形成稳定的群落,同时实现较高的固碳量。实施修复18个月后,地表盖度达到99.96%,修复植被碳密度为3 923.86 g/m^(2),新增绿地固碳总量为1 438.75 t二氧化碳,新增碳汇估算价值为12.1万元。因此,采用基于团粒喷播技术的生态修复能够有效减少旅游开发的生态补偿压力。Ecological damage and environmental costs are fundamental problems restricting the development and utilization of islands in China.In this study,we use the ecological restoration project at Sanjiao Island of Zhuhai as an example of introducing the application of aggregate spray-seeding technology on the damaged slopes of islands.We also analyzed the restorative effects and carbon sequestration value of this technology by utilizing legumes as the primary sprayed plant.The restorative impacts at different time points demonstrated that the legumes exhibited rapid growth,formed high-ground coverage,and established stable communities along with the native species while achieving significant carbon sequestration.After 18 months of restoration,the land surface coverage reached an impressive 99.96%,with a carbon density of restored vegetation of 3923.86 g/m^(2).The newly added green space sequestered a total of 1438.75 t CO_(2),and the estimated value of the additional carbon sink was 121,000 yuan RMB.Therefore,ecological restoration prior to developing and utilizing uninhabited islands has clear environmental benefits.It can effectively alleviate the pressure of ecological compensation for tourism development and is suitable for widespread promotion.
