内陆大水面水域碳汇形式、强度估算及增汇路径
Carbon sink forms of inland large water bodies and estimation of carbon sink intensity
摘要
Abstract
Building on the framework of marine carbon sequestration fisheries,this study reviews the primary forms of carbon storage in inland large water bodies—including reservoirs,lakes,and overflow areas—and examines the associated carbon sequestration mechanisms.Based on fisheries statistical data from 2021 to 2024,the study esti-mates the annual total carbon export from these water bodies in various regions of China since the commencement of the 10-year fishing ban in the Yangtze River(beginning in 2020).Finally,the study proposes feasible methods for enhancing the carbon sequestration capacity of large water bodies.The research results show that the carbon in the inland large water surface proliferation waters is retained in the form of carbon fixed by animals and plants,particu-late organic carbon(POC),dissolved organic carbon(DOC),and sediment buried at the bottom.Two important biological carbon storage mechanisms have been identified:the Biological Carbon Pump(BCP)and the Microbial Carbon Pump(MCP).Preliminary estimates of annual carbon export from China's inland water bodies for the years 2020 to 2023 are approximately 202,600 tons,166,500 tons,162,100 tons,and 162,400 tons.Inland wa-ter bodies serve as vital carbon sinks.Investigating the storage forms and sequestration mechanisms,along with ex-ploring enhancement strategies,can foster the development of carbon sequestration within China's freshwater fish-eries.This research supports efforts in the freshwater aquaculture industry toward achieving carbon peak and carbon neutrality goals.关键词
