- 摘要:
- 以黄河流域湿地保护区为研究对象，采用涡度相关法，对黄河流域不同湿地生态系统呼吸通量观测，并测定了不同湿地植被碳储量和土壤碳储量，探讨了不同湿地生态系统碳储量与呼吸的关系,探究湿地碳循作用机理,以期为保护湿地生态系统提供参考依据。结果表明：在季节尺度上，黄河流域不同湿地植被生长季具有明显的碳汇功能，生态系统呼吸(Rs)随着月份的增加呈倒“V”型变化特征；生态系统碳交换(NEE)和生态系统总初级生产力(GPP)随着月份的增加呈“V”型变化特征，在8月达到最大。不同湿地植被生物量与碳储量的分布基本一致，其中地上生物量高于地下生物量；植被碳储量大致表现为芦苇群落>苔草群落>水蓼群落>荫草群落，其中不同湿地群落植被碳储量差异均显著（P<0.05）。土壤有机碳含量和有机碳储量均呈一致的变化规律，其中以表层土壤最高，随土壤深度的增加逐渐降低，其中20～40 cm以下土壤有机碳含量变化范围相对较小；80～100 cm土壤有机碳含量最低。土壤有机碳储量和植被碳储量与生态系统碳呼吸呈显著或极显著正相关；GPP和PAR与植被碳和有机碳储量没有显著的相关性，PAR与有机碳和有机碳储量呈负相关；从相关系数绝对值来看，与土壤有机碳储量的相关系数高于植被碳储量的相关系数，并且芦苇群落、苔草群落的相关系数绝对值高于水蓼群落、荫草群落。土壤有机碳储量和植被碳储量对NEE的路径系数分别为0.52和0.43，表明土壤有机碳储量和植被碳储量直接影响黄河流域芦苇湿地NEE通量，而Rs对NEE通量起到间接的影响作用；此外，光合有效辐射与NEE呈显著负相关关系，即随着PAR的增强，芦苇湿地生态系统的固碳能力在逐渐增强。由此说明土壤有机碳储量能够更好的指示NEE通量的变化。
- Abstract:
- Taking the wetland reserve of the Yellow River Basin as the research object.By using the vorticity correlation method，the respiration flux of different wetland ecosystems in the Yellow River delta was observed，and the carbon reserves of different wetland vegetation and soil organic carbon reserves were measured，and the relationship between carbon reserves and respiration of different wetland ecosystems was discussed,the mechanism of wetland carbm cycle was explored,in order to provide reference for protecting wetlands.The results showed that，on a seasonal scale，the vegetation growth season of different wetlands in the Yellow River delta had significant carbon sink function，and the ecosystem respiration (Rs) showed an inverted ‘V’ pattern with the increase of months，reaching its maximum in August.Ecosystem carbon exchange (NEE) and ecosystem total primary productivity (GPP) showed a ‘V’ pattern as the months increase，reaching their peak in August.The distribution of vegetation biomass and carbon storage in different wetlands was basically the same，in which the aboveground biomass was higher than the underground biomass.The carbon storage of vegetation was generally shown as Phragmites>Cyperaceae>Polygonum hydropiper>Phalaris arundinacea, and the carbon storage of vegetation in different wetland communities were significantly different (P<0.05).Both soil organic carbon content and organic carbon storage showed consistent change trend，among which the topsoil was the highest and gradually decreased with the increase of soil depth.The soil organic carbon content below 20-40 cm had relatively small variation range.The soil organic carbon content in 80-100 cm was the lowest.Soil organic carbon storage and vegetation carbon storage were positively correlated with ecosystem carbon respiration.There was no significant correlation between GPP and PAR and vegetation carbon and organic carbon storage，and PAR was negatively correlated with organic carbon and organic carbon storage.From the perspective of absolute correlation coefficient，the correlation coefficient with soil organic carbon storage was higher than that of vegetation carbon storage，and the absolute correlation coefficient of Phragmites and Cyperaceae were higher than that of Polygonum hydropiper and Phalaris arundinacea.The path coefficients of soil organic carbon reserve and vegetation carbon reserve on NEE were 0.52 and 0.43，respectively，indicating that soil organic carbon reserve and vegetation carbon reserve directly affect NEE flux of Phragmites wetland in the Yellow River delta，while Rs indirectly affect NEE flux.In addition，photosynthetic effective radiation showed a significant negative correlation with NEE，that was，with the enhancement of PAR，the carbon sequestration capacity of Phragmites wetland ecosystem was gradually enhanced.This indicates that soil organic carbon reserve can better indicate the change of NEE flux.
