湿地生态系统因其强大的固碳潜力已经成为缓解全球气候变化的长期解决方案之一,然而湿地生态系统的关键碳循环过程仍然缺少系统性的总结。在保护和修复湿地的背景下,实现湿地生态系统的碳汇倍增技术途径还缺少一致的认识。本文对沼泽及泥炭湿地、河流及河岸湿地、湖泊及湖岸湿地、河口及滨海湿地四种主要湿地类型的光合碳吸收、微生物碳分解和碳沉积埋藏等碳循环关键过程进行梳理和总结。基于碳循环关键过程,进一步提出了碳汇倍增的三种技术途径,即植被固碳增汇技术、土壤碳减排技术和碳沉积埋藏技术。针对三种增汇途径又进一步细化了每种途径下的关键技术,对碳汇技术在不同湿地类型下的碳汇效应进行定性描述,并结合中国湿地区域特征给出了对应区域湿地保护和修复方法,为中国湿地生态系统碳汇倍增战略提供科学依据。

Abstract Hydrothermal pattern and vegetation community structure are key factors affecting the soil organic carbon (SOC) formation accumulation in alpine peatlands. Research on influence of SOC spatial differentiation under thaw slump erosion gullies drainage gradient, can help understand peatlands sequestration mechanism climate change. In this paper, experiments were conducted Zoige Plateau. From undisturbed peatland to edge gully formed by slump, according water level changes. Four gradient sample plots set up successively, namely undrained (Ⅰ), lightly drained (Ⅱ), moderately (Ⅲ) heavily (Ⅳ), effects characteristics content at different gradients studied. The results show that: Horizontally, dominant species succession from Carex muliensis (I) Blysmus sinocompressus (II, III) Kobresia tibetica (IV), SOC, (SWC), C/N, biomass (TB), litter count (LC), root/shoot (R/S) decreased, bulk density (BD), pH temperature (ST) increased. Vertically, Sample plot I II, III, IV firstly decreased then was highly significant positive correlation with TB, LC, R/S (p < = 0.01). Path analysis indicated that order SWC > C/N ST BD. Drainage affects ecohydrological processes, disrupts balance material input decomposition, changes horizontal vertical patterns, causing degradation.
