A GIS-based approach for mapping direct use value of ecosystem services at a county scale: Management implications

摘要: Abstract A GIS-based approach was designed to spatially estimate direct use value of ecosystem services and map results for a case study at county scale. The highlights the GIS collect data, perform spatial analysis, economic values services. Three key steps valuation agricultural products, forest tourism were illustrated in technical framework. We applied this Tiantai County (1423.8 km 2 ) Zhejiang province southeast China. Selected components natural products area mapped as data layers GIS, with each layer containing monetary every 25 m cell. total estimated RMB be approximately 538 million Yuan 2005 (Chinese currency, 8.2 Yuan = US$1), which accounted 65%, 30% 5%, respectively. critical areas management purpose identified depending on heterogeneity learned from study. explicit measures provide mechanism incorporating context into evaluation. Based present study, suggestions implications local resources protection eco-environmental extensively discussed. work expected highlight research avenues advance framework an operational basis regional ecosystem-based management.
