农业资源与环境学报 1986年第3期 23-25页

作者： r.richard Lowrance 袁剑舫

河流中养分的数量是排水区的土地利用、降雨和气候诸因子共同作用的结果。谷物地对河流中养分的数量有显著影响。河边森林相对讲没有受到污染,离河流一定距离的农地的利用情况对河流中养分数量的影响

农业流域的养分循环 Ⅰ、地下运动

农业资源与环境学报 1986年第1期 40-42页

作者： r.richard Lowrance 袁剑舫

农业地区的养分可以在地表流动,也可以在表土下面流动。究竟产生地表流动还是地下流动,取决于土壤物理性质,气候和农业管理措施。早先的研究表明,易溶性离子如NO3—N可能在地表下面流动,而溶解性比较小的养分如P则主要在地表流动。
