与灰色基础设施相比，基于自然的解决方案在防洪减灾上有哪些成本效益优势？
What cost-effectiveness advantages do nature-based solutions offer over grey infrastructure for flood control?
量化研究发现，红树林等自然屏障在减灾上常具更低单位成本与多重协同效益（如渔获、碳汇）。但 NbS 的效益具有空间异质性和不确定回报期，需与灰色工程互补而非简单替代。
Quantified studies show natural barriers such as mangroves often cost less per unit benefit and yield co-benefits like fisheries and carbon. Yet NbS benefits are spatially heterogeneous with uncertain payback periods, so they should complement rather than simply replace grey engineering.

红树林为何具有极高的蓝碳封存效率？其碳储存的主要机制是什么？
Why do mangroves have exceptionally high blue carbon sequestration efficiency and what are the main mechanisms?
红树林通过高生产力与厌氧沉积物环境实现碳封存：凋落物与根系分泌物进入缺氧土壤后分解缓慢，使有机碳长期埋藏。单位面积红树林土壤的碳密度常高于热带雨林，但盲目造林可能释放原有沉积物碳，需因地制宜。
Mangroves combine high primary productivity with anoxic sediments: litter and root exudates become slowly decomposing buried organic carbon. Their soil carbon density can exceed that of tropical forests per unit area, though ill-planned planting may release pre-existing sediment carbon.

河流自然化改造（拆坝、复原曲流）能带来哪些生态效益？
What ecological benefits come from river restoration such as dam removal and meander reconnection?
拆除废弃水坝和恢复自然弯曲河道可恢复鱼类洄游通道与洪泛湿地连通性。这类措施常显著提升生物多样性与河流自净能力。
Removing obsolete dams and restoring natural meanders reopens fish migration routes and reconnects floodplain wetlands. Such measures often markedly raise biodiversity and the river's self-purification capacity.

泥炭地修复为何被视为高性价比的气候减缓措施？
Why is peatland restoration considered a cost-effective climate mitigation measure?
泥炭地虽仅占陆地面积约 3%，却储存了约三分之一的土壤碳；退化泥炭地因排水氧化而大量排碳。复湿修复可停止排放并开始重新固碳，单位成本远低于多数工程减排。
Peatlands cover about 3% of land but store roughly a third of soil carbon; degraded ones emit heavily when drained and oxidized. Rewetting stops emissions and resumes sequestration at far lower cost than most engineered mitigation.

河岸湿地缓冲带是如何拦截农业面源污染的？
How do riparian wetland buffers intercept agricultural non-point source pollution?
河岸植被与根系土壤形成过滤带，通过物理截留、反硝化和植物吸收削减随径流进入水体的氮磷。它是控制农业面源污染、保护下游水质的基于自然的方案。
Riparian vegetation and root-zone soils form a filter strip that cuts nitrogen and phosphorus in runoff via physical trapping, denitrification, and plant uptake. It is a nature-based way to control agricultural non-point pollution and protect downstream water quality.

什么是基于自然的解决方案（NbS）？它在应对气候变化中有什么作用？
What are nature-based solutions (NbS) and what role do they play in addressing climate change?
基于自然的解决方案是指通过保护、可持续管理和修复生态系统来应对社会挑战的行动。IPCC 指出，NbS 可在 2030 年前以较低成本贡献可观的减排与碳汇。
Nature-based solutions are actions that protect, sustainably manage, and restore ecosystems to address societal challenges. The IPCC notes that NbS could deliver substantial mitigation and carbon sinks at relatively low cost by 2030.

实施基于自然的解决方案时，应如何识别和管理其协同效益与权衡？
How should co-benefits and trade-offs of nature-based solutions be identified and managed?
NbS 常同时影响碳、生物多样性、水资源和生计，需借助多指标评估框架识别协同与冲突。例如造林可能减少径流而加剧缺水，应在规划阶段进行空间权衡分析。
NbS simultaneously affect carbon, biodiversity, water, and livelihoods, requiring multi-indicator frameworks to map synergies and conflicts. Afforestation, for instance, may reduce streamflow and worsen water scarcity, so spatial trade-off analysis is needed at planning stage.
