Abstract: European wetlands store large carbon reserves1, but centuries of land use have eroded carbon stocks and biodiversity2. The European Union (EU) Nature Restoration Law (NRL)3 requires at least 30% of wetland ecosystems not in ‘good condition’ to be restored by 2030, yet spatially consistent information on wetland types and condition remains scarce. Using 10-m satellite imagery and machine learning, we map six seminatural open wetland types and land-use disturbance across 38 European countries. Wetlands are highly fragmented, with an estimated 27–33% of wetland area occurring in map-defined patches <25 ha and 7–11% in patches <1 ha, exposing many small sites missed by coarser products. We estimate that human activities affect 20.4 ± 3.4% of wetland areas (95% confidence interval), with inland wetland types most affected, and up to 5 Gt CO2-eq of soil carbon potentially lost relative to an undisturbed baseline. Translating disturbed area into NRL restoration targets, we find that several countries’ pledges are broadly consistent with our 2030 estimates, whereas others lack quantified commitments despite substantial candidate areas identified by our maps. The resulting standardized, high-resolution products provide an EU-wide baseline tailored to the NRL and a reproducible template for linking satellite mapping to restoration targets, supporting progress tracking.
摘要:湿地处于水陆交错带,储存巨大土壤碳库。但数百年土地利用改变已经造成欧洲湿地碳储量与生物多样性持续退化。欧盟《自然恢复法》(NRL)法定要求:到 2030 年,至少修复 30% 未达到 “良好状态” 的湿地生态系统。但长期以来,欧洲缺少一套空间口径统一的湿地类型与健康状况本底数据。本研究结合 10 m 卫星影像与机器学习,绘制 38 个欧洲国家 6 类半自然开放湿地与土地人为干扰分布图。结果表明欧洲湿地高度破碎化:27-33% 的湿地面积分布在小于 25 ha 的斑块中,7-11% 分布在小于 1 ha 的斑块,大量小型湿地被传统低分辨率产品忽略。估算显示,人类活动影响 20.4 ± 3.4% 的湿地面积,以内陆湿地受冲击最为严重;相较于未受干扰的基准状态,湿地土壤潜在碳损失最高可达 5 Gt CO₂eq。将受干扰湿地面积转化为 NRL 修复目标后发现:部分国家的修复承诺与本研究 2030 年科学测算目标大体吻合;但还有不少国家即便存在大片待修复湿地,仍然缺少可量化的修复承诺。本研究产出标准化高分辨率数据集,为欧盟落实《自然恢复法》提供全欧洲统一基线,同时建立一套可复现的技术框架,实现卫星遥感与生态修复政策目标的对接,支撑修复进度跟踪评估。
