目的东北黑土区是中国重要粮食产区,但长期耕作引发严重水土流失,侵蚀沟加剧耕地破碎化,威胁农业可持续发展。然而,侵蚀沟对耕地破碎化的影响缺少量化研究。方法在松嫩典型黑土分布区选取9个县的50个小流域,基于亚米级卫星影像解译土地利用和侵蚀沟,采用多个景观指标,分析耕地破碎化程度、空间差异及其主要影响因素,量化侵蚀沟对耕地破碎化的贡献率。结果1)研究区耕地综合破碎指数为0.371~0.993,破碎化程度总体上处于中等水平,呈现明显的空间差异,破碎化程度最高的地区分布在中部。2)耕地破碎化指数受多种因素影响 ...

目的探究典型黑土区切沟沟头分层土壤可蚀性K值与理化性质的关系,揭示关键因子作用机制,为黑土区水土流失治理提供理论依据。方法通过对海伦市海南乡发育在农田内的切沟沟头进行调查,选取11个典型黑土切沟沟头剖面,划分土壤层次(A层、B层、C层),采集分层土壤样品,测定土壤理化性质。根据EPIC模型计算土壤可蚀性K值。结果1)不同粒级水稳性团聚体(>5、2~5、1~2、0.5~1、>0.25 mm)均随沟头土层深度增加呈下降趋势,平均重量直径、几何平均直径、土壤总孔隙度、有机质等指标均表现为A层>
