滨海盐沼典型区域碳密度评估研究——以渤海辽河口为例
Assessment of Carbon Density in Typical Areas of Coastal Salt Marshes:A Case Study of Liaohe Estuary of the Bohai Sea
摘要
Abstract
To analyze the carbon density characteristics of coastal salt marshes and evaluate the current status of carbon density.An on-site survey was carried out in the typical coastal salt marshes in the Liaohe Estuary area of the Bohai Sea.According to the vegetation types,ecological characteristics,and topographic changes of salt marshes,27 sampling points were selected to determine the biomass and organic carbon content of vege-tation and soil samples.The carbon densities of different types of soil and vegetation were calculated,and the carbon density status and changes of salt marshes were estimated.The results indicated that the carbon densi-ty in the study area followed the descending order of bare land,Suaeda salsa area,and Phragmites australis area,which showed the average carbon densities of 166.46,114.83,and 77.06 t/ha,respectively.Sea level rise caused by climate change greatly reduced the carbon sink of coastal wetlands.The findings provide basic sup-port for wetland protection and carbon cycle research and have potential reference value for the achievement of regional carbon neutrality.关键词
