| 中文摘要: |
| 为评估不同侵蚀阻控技术对东北黑土区坡耕地减蚀保肥与增产的综合效应，本研究以吉林省东辽县典型黑土坡耕地为研究对象，设置常规耕作（CK）、等高耕作（CT）、地埂植物带（PB）、秸秆覆盖（SR）、有机肥施用（OF）及由等高耕作、地埂植物带、秸秆覆盖和有机肥施用组成的综合措施（IN）6种处理，通过连续2个生长季田间监测，分析不同侵蚀阻控技术对径流量、泥沙量、土壤理化性质及玉米产量的影响。结果表明，IN减流减沙效应最为显著，其产流量和产沙量较CK分别降低了38.4%和59.7%，两年平均泥沙产量降至2.5 t·hm-2，有效遏制了黑土层的流失；IN实施后土壤容重较CK降低9.2%，孔隙度显著提升至57.8%；土壤有机质含量显著提升47.1%，全氮及速效养分含量亦呈明显上升趋势。相关性分析表明，产沙量与土壤容重呈显著正相关，与土壤有机质含量呈显著负相关（P<0.05），表明水土流失是驱动黑土肥力退化的重要因素。总体来看，侵蚀阻控技术能够通过减流减沙、改善土壤结构和促进养分积累实现黑土坡耕地减蚀保肥与增产协同效应，其中综合措施表现最佳，可作为黑土坡耕地水土保持的优先推广模式。 |

| This study aimed to evaluate the comprehensive effects of different erosion control technologies on soil and water conservation, soil quality improvement, and crop productivity in sloping farmland of the black soil region of northeast China. A field experiment was conducted in a typical black soil sloping farmland in Dongliao County, Jilin Province, located in the hilly region of the Changbai Mountains. Six treatments were established, including conventional tillage（CK）, contour tillage（CT）, plant buffer strip（PB）, straw mulching（SR）, organic fertilizer application（OF）, and integrated measures（IN）, which combined contour tillage, vegetative field bunds, straw mulching, and organic fertilizer application. Through continuous field monitoring over two growing seasons, the effects of different erosion control technologies on runoff, sediment yield, soil phy sicochemical properties, and maize yield were evaluated. The results showed that the IN achieved the most pronounced runoff and sediment reduction effects, with runoff volume and sediment yield decreasing by 38.4% and 59.7%, respectively, compared with CK. The two-year average sediment yield was reduced to 2.5 t·hm-2, effectively mitigating black soil loss. Meanwhile, soil bulk density decreased by 9.2%, while soil porosity increased significantly to 57.8% under IN. Soil organic matter content increased by 47.1%, accompanied by notable increases in total nitrogen and available nutrient contents. Correlation analysis revealed that sediment yield was significantly positively correlated with soil bulk density and significantly negatively correlated with soil organic matter content（P<0.05）, indicating that soil erosion is an important driver of black soil fertility degradation. These findings demonstrate that erosion control technologies effectively reduce runoff and sediment losses while improving soil structure and nutrient status in black soil sloping farmland. By enhancing infiltration capacity, conserving soil nutrients, and mitigating soil degradation, these technologies promote the synergistic development of soil conservation and crop production. Among the tested treatments, the integrated measures show the greatest overall effectiveness and represent a promising management strategy for sustainable utilization and conservation of black soil resources. |
