双壳纲软体动物含碳量及年度碳储量估算——以河北昌黎黄金海岸国家级自然保护区海域为例

在2019年昌黎黄金海岸国家级自然保护区海域双壳纲软体动物调查的基础上,对该海域双壳纲软体动物含碳量进行了估算,同时分析了该保护区碳汇潜力与发展前景,以期为其他保护区海域碳储量估算提供参考依据.结果 表明,2019年昌黎自然保护区海域双壳纲软体动物含碳量约为391.79～ 414.54 t,等同于吸收了总量为1436.57～ 1520.00 t/a的CO2.年碳汇能力相当于21.80 ～ 23.07 ha的天然林地或23.47 ～ 24.83 ha的人工林地.按照2019年7个碳汇交易试点城市的平均交易价格计算,该保护区海域双壳纲软体动物每年产生的碳汇经济价值约为146677.6～155179.6元.今后应重点研究该保护区青岛文昌鱼及食物网其他层级含碳量及碳汇途径.

Estimation of carbon content and annual carbon reserves of bivalve molluscs:taking the Hebei Changli Gold Coast National Nature Reserve as an example

The carbon content of bivalve molluscs in Changli Gold Coast National Nature Reserve in 2019 was estimated by using relevant data and methods. At the same time, the carbon sequestration potential and development prospect of the reserve were analyzed and discussed in order to provide reference for carbon storage estimation of other marine reserves. The results showed that the carbon content of bivalve molluscs in Changli Nature Reserve in 2019 was about 391.79 ~ 414.54 t, equivalent to the total amount of absorbed CO2 of 1436.57 ~ 1520.00 t. The carbon sink capacity was equivalent to 21.80~23.07 ha of the natural forest and 23.47 ~ 24.83 ha of the artificial forest. According to the average transaction price of seven pilot cities in 2019, the economic value of carbon sequestration in the sea area of the reserve was about 146 677.6 ~155 179.6 yuan/a. In the future, the carbon content of Branchiostoma Belcheri Tsingtauense and other levels of food web should be studied.
