摘　　要：Assessments on ecological sensitivity and ecosystem service value are two important basic works in eco-functional regionalization. According to the special ecological environment in Guizhou Province,GIS technology was used in the classification evaluations of soil erosion sensitivity,acid rain sensitivity and rocky desertification sensitivity in Bijie Prefecture,and then the comprehensive evaluation on eco-environmental sensitivity was carried out. Finally,the preliminary economic estimation of ecosystem service value in Bijie Prefecture was made by means of the appraisal approach for ecosystem service proposed by Costanza.Assessments on ecological sensitivity and ecosystem service value are two important basic works in eco-functional regionalization.
