Integrated methods and scenarios for assessment of sand dunes ecosystem services

摘要: Abstract Anthropogenic and natural ecosystems in coastal dunes provide considerable benefits to human well-being. However, date, we still lack a good understanding of how ecosystem services (ES) supply varies from young (e.g., embryo fore dunes) mature brown red dunes). This study proposed novel modelling methodology by integrating an expert-based matrix, Bayesian Belief Network (BBN), structural equation model, scenario development method. It aims at evaluating dune for the sustainable areas. The model was tested using data collected Vietnam. An matrix assess capacity 18 ES different types generated with participation 21 interdisciplinary scientists. found that could most regulation cultural services, while gray provided least amount. Results analysis recommended decision-making is able optimize multiple ES by: (i) keeping embryo/fore their state instead them mineral mining urbanization; (ii) enlarging certified protected forests areas yellow dunes; (iii) optimizing dunes.
