模拟降雨下坡面草带分布对产流产沙过程的影响

open access: yesShuitu Baochi Xuebao, 2022
为深入探讨坡面植被分布对产流产沙过程的影响,定量分析植被分布与坡面产流产沙的关系,通过人工降雨试验,在15°坡面条件下,对不同植被覆盖度(40%,60%)、不同降雨强度(30,60,90 mm/h)和不同植被分布位置(相对距离为0,0.2,0.4,0.6,0.8,1.0)条件下的坡面产流产沙进行观测,分析不同植被分布条件下的水土保持作用,提出了不同覆盖度下控制水土流失的植被优化配置。结果表明:(1)在一定坡度和降雨强度条件下,不同植被分布条件下坡面产流率和产沙率均表现为先迅速增加后趋于稳定的变化趋势 ...

植被覆盖变化与土壤保持演变空间异质性研究

open access: yesShuitu Baochi Xuebao, 2023
为定量研究植被覆盖与土壤保持两者之间的关系及植被覆盖对土壤保持的影响,选取十大孔兑为研究区,利用趋势分析法、空间自相关分析、InVEST模型,重点分析十大孔兑2000-2020年植被覆盖、土壤保持时空变化及植被覆盖变化对土壤保持的作用。结果表明:(1)研究期内,十大孔兑区植被覆盖均呈增加趋势;(2)2000-2020年,土壤保持量随着植被覆盖的增加而增加,说明植被覆盖增加对于土壤侵蚀有明显的抑制作用,对土壤保持服务功能有明显的促进作用;(3)植被覆盖与土壤保持局部空间自相关,Moran's ...
