摘要
红树林生态系统脆弱且易遭破坏,城市红树林湿地更易受城市建设和经济发展的影响,因此其保护、管理、修复和可持续发展具有重要意义。本研究以2003、2013、2018、2023年的深圳福田红树林湿地遥感影像为数据源,结合土地利用/覆被变化(LUCC)和景观生态指数分析2003—2023年湿地中红树林、基围、滩涂、建筑用地、水域、林地的动态变化。结果表明:2003—2023年,福田红树林面积呈增长趋势,从68.97 hm^(2)增至110.75 hm^(2),其中,2013—2018年为增长最快阶段,年均增长率为4.87%。基围面积由50.38 hm^(2)下降至46.13 hm^(2),滩涂面积从199.64 hm^(2)下降至156.21 hm^(2),建筑用地、水域和林地面积动态稳定。红树林湿地的斑块密度和数量上升,而蔓延度指数降低,表明红树林湿地景观斑块间分离、破碎化程度加剧。2003—2023年红树林总面积逐年增加,主要源于红树林与滩涂之间的面积转换。研究结果可为福田红树林国家重要湿地的修复和功能保育技术开发提供基础,也为湿地修复和可持续管理提供数据参考。
Mangrove ecosystems are highly vulnerable and susceptible to degradation.Urban mangrove wetlands,in particular,face greater threats from urban development and economic expansion,making their conservation,management,restoration,and sustainable development critically important.This study utilized remote sensing imagery of the Futian Mangrove Wetland in Shenzhen in 2003,2013,2018 and 2023 as the data source,and analysis he dynamic changes in mangrove forests,fish ponds,tidal flats,construction land,water bodies,and forested areas within the wetland from 2003 to 2023 by integrating Land Use/Land Cover Change(LUCC)and landscape ecological indices.The results show that the mangrove area in the study region showed an increasing trend from 2003 to 2023,rising from 68.97 hm^(2) to 110.75 hm^(2).The fastest growth occurred from 2013 to 2018,with an average annual growth rate of 4.87%.The area of fish ponds decreased from 50.38 hm^(2) to 46.13 hm^(2),and the area of tidal flats declined from 199.64 hm^(2) to 156.21 hm^(2),while the areas of construction land,water bodies,and forest land remained relatively stable.The patch density and number of mangrove wetlands increased,while the contagion index decreased,which indicates that the separation and fragmentation degree of landscape patches in mangrove wetlands have intensified.The total mangrove area increased annually from 2003 to 2023,which is mainly attributed to the area conversion between mangroves and tidal flats.These findings provide a basis for the development of restoration and functional conservation techniques for the Futian Mangrove National Important Wetland,and also offer further data references for wetlands restoration and sustainable management.
