摘　　要：生态敏感性和生态系统服务功能价值分析评价,是生态功能区划中的两项重要的基础性工作,根据贵州省特殊生态环境应用GIS技术对贵州省毕节地区的土壤侵蚀敏感性、石漠化敏感性及酸雨敏感性进行分级评价,然后进行生态环境敏感性综合评价;根据Costan-za提出的对生态系统服务功能的估价方法将毕节地区生态系统服务功能价值作初步经济估算。Analysis on ecological sensitivity and value of ecosystem service are the two important basic work in eco-functional regionalization.GIS technology was used to make classification and assessment on the sensitivity of soil erosion,acid rain sensitivity and the sensitivity of rocky desertification according to the special ecological environment of Guizhou Province,then a comprehensive evaluation on eco-sensitivity was carried out.Finally,a preliminary economic estimates on the basis of value of ecosystem services was completed according to the method of valuation of ecosystem services proposed by Costanza.
