1. Wetlands are some of the most important ecosystems on Earth. They play a key role in mitigating climate change-related events and filtering polluted water, and provide habitats for a wide range of species. Despite their importance, and numerous regulations that support their conservation, wetlands continue to be destroyed. Recent reports have indicated a progressive decline in ecological character of remaining wetlands.
2. This research reviews and extends the present status of wetland knowledge in Sardinia, the second largest Mediterranean island. For the first time, Sardinian wetlands were comprehensively mapped using satellite images and field validation. Impacts were also assessed. Trends in literature published about Sardinian wetlands since 1900 were then analysed, mainly according to the location(s) and topic(s) studied.
3. In total, 2,501 Sardinian wetland sites were identified. The most common impacts observed in the field were vegetative degradation and water pollution. Of these wetlands, 2,274 have never been the subject of a research paper. Despite recent increases in publication rates, there was a lack of even basic knowledge about many wetlands, especially smaller ones. Larger wetlands have been studied from a range of viewpoints.
4. In the light of these results, suggestions for improved awareness, effective management and conservation of Mediterranean wetlands were established. Future work should be directed to filling gaps in basic information, and to improvements in research and conservation, which might include multidisciplinary approaches in support of more comprehensive conservation management plans.

地中海湿地保护的知识差距和挑战：来自撒丁岛综合清单和文献分析的证据

1. 湿地是地球上最重要的生态系统之一。它们在缓解气候变化相关事件和过滤污染水方面发挥着关键作用，并为各种物种提供栖息地。尽管湿地很重要，并且有许多支持其保护的法规，但湿地仍在继续遭到破坏。最近的报告表明，剩余湿地的生态特征逐渐下降。
2. 本研究回顾并扩展了地中海第二大岛撒丁岛湿地知识的现状。首次使用卫星图像和实地验证对撒丁岛湿地进行了全面测绘。还评估了影响。然后分析了自 1900 年以来发表的关于撒丁岛湿地的文献趋势，主要是根据研究的地点和主题。
3. 总共确定了 2,501 个撒丁岛湿地地点。在实地观察到的最常见的影响是植物退化和水污染。在这些湿地中，有 2,274 个从未成为研究论文的主题。尽管最近发表率有所提高，但对许多湿地，尤其是较小的湿地，甚至缺乏基本知识。已经从各种角度研究了更大的湿地。
4. 根据这些结果，提出了提高地中海湿地意识、有效管理和保护的建议。未来的工作应致力于填补基本信息方面的空白，并改进研究和保护，其中可能包括支持更全面的保护管理计划的多学科方法。
