Chinese. 为了建立黄土高原生态治理评价体系和选择合适的评价方法，选取陕北各县多年观测资料，建立黄土高原生态综合治理评价指标体系，应用层次分析法、灰色聚类法和Topsis法对各县域生态治理效益进行了分析评价。结果表明：在陕北黄土高原生态治理过程中，坝地面积、治理度和单位面积投资是该地区生态治理评价体系的主要影响因子，在实际运行中应加以重视；各县域生态治理局势存在波折，但整体呈良性发展，并为良好治理措施的选择提供现实依据，评价结果与实际情况相符。生态治理效益评价体系的建立以及这3种方法的结合运用为县域生态治理效益评价工作提供科学依据，有利于黄土高原生态治理局势的综合管理与宏观调控。[著者文摘]
