人类活动很大程度上影响农田土壤质量和土壤成分。采集陕西省黄土高原关中地区典型人为楼土土壤样品，测定土壤压实度、容重、总有机碳（TOC）、活性有机碳（AOC）和土壤酶活性，探讨土壤质量的空间变化。结果表明，土壤压实度和容重随着距农田距离的增加而增大，而土壤TOC、AOC和土壤酶活性则随着距农田距离的增加先增大后减小。所有测试参数均呈现清晰的同心圆分布。垂直方向上，表土的土壤压实度和容重均低于下层土，但表层土的所有其他测试参数均显着高于下层土。此外，有机碳含量与酶活性之间存在显着的正相关关系，证实了楼土土壤特征的空间分布在一定程度上受到了长期人类活动的影响。本研究结果表明，施用农家肥和适当深耕是保持和改善土壤质量的重要而有效的方法。
Anthropogenic activities largely influence the soil quality of agricultural fields and the composition of soil. Samples of typical anthropogenic Loutu soil in the Guanzhong area of the Loess Plateau, Shaanxi Province, China were collected and measured for soil compaction, bulk density, total organic carbon (TOC), active organic carbon (AOC), and soil enzyme activities to investigate spatial variations in soil quality. The results indicate that soil compaction and bulk density increased with increasing distance from the farm village, whereas soil TOC, AOC, and soil enzyme activities firstly increased and subsequently decreased with increasing distance from the farm village. All of the tested parameters presented clear concentric distribution. Vertically, soil compaction and bulk density in the topsoil were lower than those in the subsoil, but all other tested parameters in the topsoil were significantly higher than those in the subsoil. In addition, there was a significant positive correlation between organic carbon content and enzyme activities, confirming that the spatial distribution of Loutu soil characteristics has been affected by long-term anthropogenic activities to some extent. The results of this study imply that the use of farmyard manure and appropriate deep plowing are important and effective ways to maintain and improve soil quality.
