东北黑土区土壤退化及水土流失研究现状

The Status Quo of Black Soil Degradation and Water and Soil Loss in Northeast China

东北黑土区严重的水土流失破坏了宝贵的黑土资源,危及当地群众的生产生活条件,恶化了生态环境,制约了当地经济社会的可持续发展,对我国的粮食安全构成了严重威胁。当前黑土区土壤退化及水土流失研究的领域主要集中在:现状研究、影响因素研究以及土壤侵蚀研究。在概述当前黑土区土壤退化及水土流失研究概况的基础上,指出应该加强研究的领域在于综合性的水土流失研究,融雪侵蚀模拟,先进的土壤侵蚀预报模型应用等方面。

Due to severe water and soil loss, the precious black soil resources is being destroyed in Northeast China. The main fields of previous studies are mainly on status quo investigation, influence, soil erosion in black soil district. On the basis of the previous studies on black soil degradation and water soil loss in Northeast China, the research fields are proposed, which include the integrated study on water and soil loss, development and application of soil erosion models, snowmelt erosion simulation etc.
