Evaluation and Spatial Distribution of Marine Ecosystem Service Value in Jiangmen City
摘要
Abstract
Based on the Common International Classification of Ecosystem Services(CICES),marine ecosystem services were categorized into 3 major categories and 10 sub-categories.Integrating GIS technology with valuation methodologies including market price method,replacement cost method,and pollution prevention cost method,this study conducts a quantitative assessment and spatial distribution analysis of the provisioning,regulating,and cultural service values of marine ecosystems in Jiangmen City.The results showed that:(1)In 2022,the total marine ecosystem service value(MESV)of Jiangmen City reached 174.96×108 RMB,comprising 44.73%provisioning services,37.94%regulating services,and 17.33%cultural services,with the unit MESV of 358.53×104 RMB/km2;(2)The nearshore shellfish aquaculture industry not only provides food supply but also delivers additional climate regulation and waste regulation service values,accounting for approximately 9%of the total MESV;(3)The spatial distribution density of MESV generally shows a gradual decline from nearshore to offshore areas.Within nearshore zones,MESV primarily depends on aquaculture production,while in offshore areas,it is mainly determined by primary productivity.The study suggests that developing marine aquaculture in offshore areas and scientifically and rationally exploiting marine ecological resources can effectively enhance ecosystem service functions,thereby achieving the synergistic advancement of ecological conservation and resource utilization.关键词
