摘要:

[目的] 研究地边截水地物对黑土区小流域坡长因子（L）和土壤侵蚀速率（A）的影响，为提高该地区的土壤侵蚀预报精度提供依据。[方法] 选取2个小流域，结合野外调查和DEM分析，比较不考虑与考虑地边截水地物情况下的L。[结果] 如果不考虑地边截水地物，L平均被高估18%，A平均被高估31%。[结论] 在计算黑土区小流域土壤侵蚀速率时，有必要考虑地边截水地物。在其他因素相同的情况下，坡度越大，横坡分布的地边截水地物的间距越小，越要考虑地边截水地物。

Abstract:

[Objective] The effects of parcel-border features (PBFs) on the calculation of the slope length factor and soil erosion rate of small watersheds in a black soil region were studied in order to provide a basis to improve the precision of soil erosion prediction in the region.[Methods] Two typical small watersheds were selected. Field survey and digital elevation model analysis were used to calculate the slope length factor considering the PBF, and the PBF was ignored.[Results] The slope length factor could be overestimated by 18% and the soil erosion rate by 31%, on average.[Conclusion] It is necessary to consider PBFs for the slope length factor and soil erosion rate calculations of small watersheds in black soil region. Similarly, under other factors, it would be necessary to consider PBFs when the slope gradients are larger and the intervals between cross-slope PBFs are smaller.
