东北黑土区冻融循环对切沟沟壁崩塌的影响

open access: yesShuitu Baochi Xuebao
[目的] 通过测量冻融循环期间沟壁崩塌体积来评价冻融循环对切沟侵蚀的贡献。[方法] 2016—2018年间,选取36条切沟共计463个崩塌点开展了野外调查。基于调查结果,切沟沟壁崩塌主要表现为2种类型:块状崩塌和松散堆积。在每个崩塌点测量2种堆积体的形态参数:崩塌土壤的体积、切沟横断面的宽度和深度,以及相应沟壁土壤的剪切力和硬度。[结果] (1)3年研究期间冻融作用导致的沟壁崩塌强度平均为16.12 m3/(km·a)。2种崩塌类型在切沟内随机发生,单点冻融崩塌量主要集中在0~3 m3 ...
