[目的]研究土地利用方式和季节变化对土壤养分剖面分布的影响。[方法]以柴河流域为例,系统分析了设施农业、传统农业、林地、坡耕地、落荒地5种土地利用方式下土壤养分状况。[结果]不同土地利用方式对土壤全氮、全磷、有机质含量有显著的影响,以传统农业和设施农业含量最高。不同土地利用方式土壤养分由表层至底层呈下降趋势,尤以设施农业和传统农业2种受人类活动影响剧烈类型土壤下降更快。[结论]季节对土壤养分含量有显著影响。
[Objective] The research aimed to study the effects of land use patterns and seasonal variations on soil nutrient profile distribution. [Method] With the example of Chaihe River Basin, the status of soil nutrients under five land use types including facility agriculture, traditional agriculture, woodland, sloping land and wasteland was systematically analyzed. [Result] Different types of land use had significant effects on soil total nitrogen, total phosphorus and organic matter content, with the highest content of traditional agriculture and facility agriculture. Soil nutrients in different land-use types showed a downward trend from the surface to the bottom, especially in the violent types of soils affected by human activities, such as facilities agriculture and traditional agriculture. [Conclusion] Season had a significant effect on soil nutrient content.
