摘要
从河流地貌角度,提出了包括河道横向形态多样性、纵向蜿蜒性、铅直向渗透性、河道稳定性及河岸带状况5大要素构成的指标体系及5级评价标准,构建了模糊层次综合评价模型,并对辽河中下游柳河口至盘山闸段进行地貌评价,判断其地貌现状及限制因子,为日后保护、修复与管理提供了决策依据。
Based on the stream geomorphy,this paper proposes an index system and five-level evaluation criteria,which includes transverse morphological diversity of river,vertical meandering,vertical permeability,channel stability and riparian condition.And fuzzy hierarchical comprehensive evaluation model is established.Then the landform in middle and lower reaches of Liao River between Liuhekou to Panshanzha segment is evaluated.Finally,the current situation of topography and the limiting factors are determined.Therefore,it provides a decision-making for the future protection,restoration and management.
