Hydraulic digital terrain model (DTM) is an advanced technology which combines hydraulic analysis and traditional DTM.Based on hydraulic DTM,the Danube River Restoration in Ertingen-Binzwangen shows how hydraulic research of the Danube River,river landscape design and landscape construction can work hand in hand,in order to optimize landscape water system design and control intensity of human invention on natural system,as such to maintain landscape ecological balance or construct landscape ecosystem in virtuous circle.%数字水文地形模型是将水力学的数据分析与传统数字地形模型结合的先进技术.在德国埃尔廷根-宾茨旺根段多瑙河河流修复工程中,以数字水文地形模型为核心技术优化景观水系设计,多瑙河水力学研究、河流景观设计以及景观施工等不同阶段一环扣一环紧密衔接,优化景观水系设计,以合理控制人类对自然的干扰强度,保持景观生态平衡状态或构建良性循环的景观生态系统.
