| 摘 要： | 融雪侵蚀在中国及世界上许多地区都有发生,其对表层土壤的破坏作用越来越为人们所认识,已成为土壤侵蚀研究中的重要问题之一。在总结相关研究成果的基础上,分析了影响积雪和融雪的气候、海拔、地形地貌及土地利用等因素。在融雪侵蚀影响因素方面,认为融雪径流、表层土壤解冻深度、解冻期表层土壤可蚀性是影响融雪侵蚀发生的特殊因素。同时指出,融雪侵蚀预报模型中冻融作用对土壤水分迁移的影响、未完全解冻层对表层土壤水分的影响以及坡面融雪过程研究是未来融雪侵蚀研究中应重点解决的问题。

| Abstract: | Snowmelt erosion has occurred in our country and in many parts of the world. Its role in the destruction of topsoil is increasingly being recognized. On the basis of summarizing the research results, this paper analyzed the impacts of snow accumulation and snowmelt.The impacts include climate, elevation, topography, and land use and other factors. This paper pointed out that snowmelt runoff, surface soil thaw depth and weak soil erodibility in early spring are the special influence factors induced snowmelt erosion. Meanwhile, the article points out that snowmelt erosion research should be strengthened in three areas. First, freezing-thawing on soil moisture migration should be taken into account in snowmelt erosion prediction model. Second, not completely thawed layer on the surface soil moisture effects should have a deeper understanding. The third area, snowmelt process research on slope should be focused on solving the problem in the future snowmelt erosion study. |
