摘要
选择马来西亚诗巫-丁宜群岛作为研究区域,基于暴露-敏感-适应(ESA)模型构建了海草床与珊瑚礁生态脆弱性评价指标体系,结合空间分析技术评估海草床与珊瑚礁的生态脆弱性状况及其空间分布。结果表明:诗巫-丁宜群岛海草床与珊瑚礁生态系统暴露性在空间分布上呈现从北部到南部逐渐增加的趋势,海草床生态系统的敏感性整体上高于珊瑚礁生态系统,多数站位的生态脆弱性处于中等水平;海草床生态系统的脆弱性普遍高于珊瑚礁生态系统,暴露性和敏感性对海草床与珊瑚礁生态脆弱性的影响并非都是相对独立的。提高海水质量和实施海洋公园分区管理,对降低诗巫-丁宜群岛海洋生态系统的脆弱性有积极意义;同时,也要加强对海草床与珊瑚礁生态系统的整体保护。
We developed the assessment index system for the ecological vulnerability of seagrass beds and coral reefs in Sibu-Tinggi Archipelago, Malaysia, based on the Exposure-Sensitivity-Adaptive(ESA) model. The ecolo-gical vulnerability and spatial distribution of seagrass beds and coral reefs were assessed in combination with spatial analysis technology. The results showed that the spatial distribution of exposure of seagrass beds and coral reefs in Sibu-Tinggi Archipelago displayed an increasing trend from the north part to the south part. Generally, the sensitivity of seagrass beds was higher than that of coral reefs, and the ecological vulnerability of most stations were at a medium level. The vulnerability of seagrass beds was generally higher than that of coral reefs. The effects of exposure and sensitivity on the ecological vulnerability of seagrass beds and coral reefs were not relatively independent. Improving seawater quality and zoning management of marine parks have positive implications for reducing the vulnerability of marine ecosystem in Sibu-Tinggi Archipelago. Meanwhile, it is necessary to strengthen the integrated conservation of seagrass bed and coral reef ecosystems.
