摘要： 红树林生态修复评价是衡量生态恢复成效、保障生态功能稳定的关键。为探究不同立地条件对红树林修复成效的影响, 本研究以雷州市洪流北、卜昌, 惠州市望京洲、大埔屯四个广东典型红树林修复区域为研究对象, 系统调查新营造红树群落的生长指标(株高、基径)及沉积物理化性质(粒度、有机碳、总氮、总磷等)并对研究区域的红树林修复成效进行量化评估。与种植初期相比, 望京洲的红树植株的总生长增幅最高(124.76%), 且主要集中在株高生长。红树植株保存率从高到低依次为望京洲(72.29%)、大埔屯(60.00%)、洪流北(42.25%)和卜昌(39.32%)。望京洲和大埔屯沉积物粘土数量、有机碳含量均高于其它两个修复区域。基于熵权法赋权的评价结果表明, 望京洲红树林修复成效属于“优”等级(综合得分3.26), 大埔屯属于“良”等级(综合得分2.51), 卜昌、洪流北则均属于“中”等级(综合得分分别为1.93和1.76)。滩面高程、沉积物粘土含量和有机碳含量可能是影响红树林修复成效的重要因素。本研究为当前红树林修复成效评价提供了应用实例, 并为红树林生态修复工程的适应性规划提供了科学依据。

Abstract: Evaluating of mangrove restoration is essential for assessing the effectiveness of ecological restoration and ensuring the stability of ecological functions of mangroves. To investigate the impact of site conditions on mangrove restoration effectiveness, four representative regions of mangrove restoration in Guangdong Province including Hongliubei, Buchang located in Leizhou City, Wangjingzhou, Dabutun situated in Huizhou City were selected in this study. Growth parameters (stem height, basal diameter) of newly established mangroves, as well as sediment physicochemical properties (e.g., grain size, sediment organic carbon, total nitrogen and total phosphorus) were quantitatively determined for evaluating the restoration effectiveness of the study areas. Compared to initial planting stage, mangroves associated with Wangjingzhou showed the highest total growth rate (124.76%), primarily focusing on the stem height growing. The highest preservation rates of mangroves was also observed Wangjingzhou (72.29%), followed by Dabutun (60.00%), Hongliubei (42.25%) and Buchang (39.32%). Sediment clay content and organic carbon concentration were higher in Wangjingzhou and Dabutun in comparison with Hongliubei and Buchang. The result of evaluation based on entropy weight model presented that the restoration effectiveness in Wangjingzhou was rated as “excellent” (with final score of 3.26), Dabutun as “good” (scoring 2.51), and both Buchang and Hongliubei as “medium” (scoring 1.93 and 1.76, respectively). Elevation of intertidal flat, sediment clay content and organic carbon concentration may play a crucial role in demonstrating the variation in mangrove restoration effectiveness. The present investigation not only provided a case study on mangrove restoration evaluation, but also offered scientific insights for informing the adaptive formulation of mangrove restoration engineering.
