滇池螺类碳汇分布储存特征研究
Study on Carbon Sink Distribution and Storage Characteristics of Snails in Dianchi Lake Area
摘要
Abstract
Morphological identification and volume method were used to determine the calcium carbonate content,IBM SPSS Statistics 26 software was used for data analysis,and ArcGIS 10.2 and Origin 2022 software were used for mapping to explore the size and distribution of carbon sink effects of snails in the Dianchi Lake area.The results show that:(1)Margarya melanioides quantity is the most,accounting for 56.99%,followed by Semisulcospira cancellata,Anodonta woodianawoodiana,Oncomelania hupensis Robertson,and Cipangopaludina chinensis and Bellamya purificata are the lowest,accounting for less than 1.00%.(2)There are significant differences in the morphological characteristics among different snail species.Semisulcospira cancellata had the largest shell surface area and the best carbon sequestration ability,with the average carbon content of 112.94 mg/g.followed by Oncomelania hupensis Robertsoni,while Anodonta woodianawoodiana and Margarya melanioides have relatively lower carbon contents,with means around 70.00 mg/g.(3)Except for Semisulcospira cancellata,the carbon sequestrations of the other three species were negatively correlated with shell height,shell width and shell weight.The carbon sink in the snail community in Dianchi Lake area is primarily concentrated in Semisulcospira cancellata,followed by Margarya melanioides.This study can provide a scientific basis and reference for carbon storage assessment and ecological restoration in the Dianchi Lake and its surrounding areas.关键词
