在自然界中 ,泥石流形成环境、发育规律、空间分布等特征的演化和分异 ,导致了不同时期、不同区域、不同沉积过程和不同沉积地貌部位泥石流沉积亚相组合的变异。该文拟在作者所建泥石流沉积模式基础上 ,以蒋家沟为例进一步讨论泥石流亚相的组合及变异规律。此外 ,初步探讨了夷平面解体后 ,泥石流沉积在地貌回春不同阶段的发育规律。
In nature, the evolution and differentiation of debris flow forming environment, developmental patterns and spatial distribution have led to the variation of debris flow sedimentation subfacies in different periods, different regions, different sedimentary processes and different sedimentary landforms. Based on the sedimentary model of debris flow constructed by the authors, the article takes Jiangjiagou as an example to further discuss the law of combination and variation of debris flow subfacies. In addition, the law of development of debris flow sediment in different stages of landscape rejuvenation after the disintegration of barren surface was discussed.
