摘　　要：通过收集资料与咨询专家,选取出影响侵蚀沟发育及体现沟蚀环境现状的4类因素中的13个评价因子,以此构建了黑土区坡耕地侵蚀沟生态环境状况诊断与评价指标体系。基于层次分析法对黑土区坡耕地侵蚀沟生态环境状况进行了综合评价。研究结果表明:黑土区坡耕地侵蚀沟生态环境状况综合评价值为74.60分(满分100分),说明黑土区侵蚀沟目前正处于强烈侵蚀状态;4类影响因素中的地形因素、侵蚀沟形态特征、人为因素和气象因素综合评价值分别为76分、75分、65分和78分,说明人为因素是造成该区侵蚀沟剧烈发展的最主要因素;根据4类影响因素的综合评价值,分别提出了使各影响因素有利于抑制沟蚀发展的治理性建议。Based on data collection and expert consultation,thirteen evaluation factors among the four types of factors affecting the development of erosion gully and reflecting the current situation of erosion environment were selected to construct the diagnosis and evaluation index system of the ecological environment of erosion gully of sloping farmland in black soil area.Based on analytic hierarchy process(AHP),the ecological environment of slope farmland erosion gully in black soil area was evaluated comprehensively.The results showed that the comprehensive evaluation value of slope farmland erosion gully in the black soil area was 74.60 points(full score:100),indicating that the erosion gully in the black soil area was in a state of intense erosion at present.The comprehensive evaluation values of topographic factors,morphological characteristics of erosion gully,meteorological factors and human factors were 76 points,75 points,65 points and 78 points respectively,indicating that human factors were the most important factors causing the drastic development of erosion gully in this area.According to the comprehensive evaluation value of the four kinds of influencing factors,the governance suggestions were put forward to make each influencing factor conducive to inhibiting the development of gully erosion.
