摘要
研究分析黄土高原北部坡耕地土壤侵蚀对土壤性质影响结果表明,山坡中、上部为土壤侵蚀最强烈地带,坡顶侵蚀较弱;土壤全N、碱解氮、速效钾与水蚀和耕作侵蚀间呈线性相关关系,而土壤有机质、速效磷和阳离子代换量则与水蚀和耕作侵蚀无显著相关性。
The effects of soil erosion on the soil properties of northern Loess Plateau were studied. The results show that the erosions in the front and middle parts of the slope cropland are stronger, but the erosion is weaker in the top of slope. There is linear relations among total N, alkaline hydrolysis N, available K and water erosion, tillage erosion; organic matter, available P, and cation exchange capacity are related to water erosion and tillage erosion insignificantly.
