由于黄土切沟在流域侵蚀产沙和地貌发育方面的重要性,越来越多的研究逐渐将切沟从混合着各类沟谷的沟谷系统中分离出来,以明确对其特征、发育演化与环境的耦合作用.针对目前黄土切沟定义内涵不统一、表达相混淆的问题,该文首先在分析已有概念的基础上,明确了黄土切沟所具有的共性特征,并基于此,介绍了目前关于切沟的自动化识别、切沟的形态特征分析以及切沟的发育演化模拟等地貌学方面的研究进展.认为目前关于黄土切沟的系统研究仍处于起步阶段,今后的研究重点将在切沟的自动识别、三维形态监测与信息提取以及基于系统动力学的切沟地貌演化模型的构建等方面.
Progress in Geomorphology Research on Young Gully in Loess Plateau
Recently an increasing number of researchers show the interests in loess young gully and distinguish it from gully system which include rill,shallow gully,young gully,gully and river,due to its important role in watershed erosion sediments and geomorphologic development.They all focus on a deep understanding the characteristics of loess young gully,and its development,evolution with environment.Therefore this paper has done a review of research work about the conception,classification,automatic identification method,morphological characteristics analysis and development simulation of young gully.Based on those research work,the common geomorphologic characteristic is summarized by a comprehensive analysis of the existing definition.It is proposed that the future research will focus on automatic identification,three-dimension morphologic extraction and monitoring,morphological characteristics analysis,modeling gully development evolution based on system dynamics.
