东北半干旱区侵蚀沟土壤物理特征研究

Investigation of Erosion Gully and Soil Physical Characteristics in Semi-Arid Areas of Northeast

摘要: 随着开发力度不断加大，东北黑土区水土流失问题引起了广泛关注，其中侵蚀沟的发生发展及危害尤为引人注目。目前，国家针对黑土侵蚀沟问题投入了巨大的人力物力进行工程治理，但侵蚀沟的基础研究相对滞后。对此，针对侵蚀沟土壤的水分含量、粒径组成以及土壤容重展开研究，以期为后续侵蚀沟治理提供理论依据。

Abstract: As development continues to increase, the problem of soil erosion in the black soil region of North-east China has aroused widespread concern. The occurrence and development of the erosion ditch and its hazard are particularly noticeable. At present, the state has invested enormous manpower and material resources in engineering management for the problem of black soil erosion ditch. However, the basic research on erosion ditch is relatively lagging behind. In this regard, this paper carries out the research on the moisture content, particle size composition and soil bulk density of erosion gully soil in order to provide a theoretical basis for the subsequent treatment of erosion gully.
