農地生態系服務價值指標之建構──網路程序分析法之應用

Using Analytical Network Process to Construct the Indicator Framework of Agricultural Land Ecosystem Services

本研究利用ANP 建構臺灣不同種類農地之生態系服務指標架構，其中十二項生態系服務，水資源之水資源蓄存、水質淨化、緩減洪水氾濫；土壤資源之土壤保育、養分循環、植物修復；生物資源之生物多樣性、授粉／種子傳播、病蟲害防治；大氣資源之空氣淨化、碳吸存／減碳、調節微氣候。各項生態系服務對應七種土地利用類型，分別為旱田、水田、有機栽培、特用作物、造林地、魚塭地、畜牧地。架構分析各項生態系服務結果顯示，多數農地利用類型皆以生物多樣性與水資源蓄存具有最高權重值，以植物修復權重值最低。

This study uses ANP to construct an ecosystem service index framework for different types of farmland in Taiwan, including the following 12 ecosystem services: water storage of water resources, water quality purification, and flood mitigation; conservation of soil resources, nutrient cycling, and restoration of plants; biodiversity of biological resources, pollination/seed propagation, and pest control; air purification of atmospheric resources, carbon sequestration/carbon reduction, and microclimate regulation. Each ecosystem service corresponds to seven types of land use, including dry land, paddy field, organic cultivation, special crops, afforestation land, fish farm land, and livestock land. The results of structural analysis of various ecosystem services show that most types of farmland use have the highest weighted value for biodiversity and water storage, and the lowest weighted value for phytoremediation.
