摘　　要：本研究选取了地形、侵蚀沟形态、人为何气象因素作为坡耕地侵蚀沟生态环境诊断的初选质保,采用层次分析法构建了包含13项评价指标的侵蚀沟道生态环境健康诊断体系,并利用加法模型对坡耕地侵蚀沟生态环境进行健康诊断与评价。评价结果表明,黑土区坡耕地侵蚀沟生态环境健康综合评价值为74.60分,健康水平较差,属于强烈侵蚀状态。未来应加强黑土区坡耕地侵蚀沟道治理,防治沟蚀发育与发展。Factors of topography,degree of gully erosion,anthropogenic and atmosphere were selected as initial indexes on ecological environment diagnosis of erosion gullies on sloping land in this study.Analytic Hierarchy Process was applied to construct the diagnosis system including 13 evaluating indexes.Also,additive model was used to diagnose and evaluate ecological environment health of gully on sloping land.The results indicated the comprehensive evaluation value on ecological environment health of gully in Black Soil Region was 74.60 points which was at poor level.The erosion degree was in the state of serious erosion.The control of erosion gully on sloping land in Black Soil Region should be paid more attention in the future to prevent gully development.
