摘　　要：火星南部高地的山谷网络长期以来被视为火星表面存在过流动水的有力证据,提取火星山谷网络有助于估算火星历史上的水含量,探寻火星表面水演化历史。将火星山谷网络提取方法分为手工绘制与自动提取两大类,对相关研究进行梳理,分析现有方法的特点并提出可能改进方向。The valley network in the southern highlands of Mars has long been considered as the strong evidence for the presence of flowing water on its surface Extracting the valley network can help estimate water content in the history of Mars and explore the evolution of water on the surface of Mars We divide the extraction methods of Mars valley network into two categories:manual rendering and automatic extraction We sort out the relevant researches,and analyze the characteristics of the existing methods to propose possible improvement direction.
