  "abstract": "目的探讨黄土丘陵沟壑区高陡边坡生物结皮发育后对土壤基本性状、抗蚀性及径流水动力学特性的影响，分析其对边坡水力侵蚀的减控作用，为黄土边坡防护和沟道侵蚀治理提供科学依据。方法通过模拟冲刷、单雨滴击溅及静水崩解试验，测定3种坡度、3种雨强下生物结皮边坡与裸土边坡的初始产流时间、坡面流速和侵蚀量等差异，对比分析生物结皮对边坡侵蚀的防护效应及其途径。结果1）高陡边坡生物结皮覆盖下土壤有机质含量较无结皮覆盖土壤平均升高124.3%，团聚体含量显著提高44.9%，土壤饱和含水量和饱和导水率分别平均降低7.9%和39.5%，生物结皮显著改善高陡边坡土壤的基本理化性质。2）与无结皮土壤相比，生物结皮覆盖边坡土壤的击穿动能平均为无结皮土壤的5.6倍，单雨滴溅蚀量减少83.7%，坡面初始产流时间提前38.2 s，坡面流速提高6.2%，总径流量增加7.2%，生物结皮显著增强边坡土壤的抗蚀性，并影响径流水动力学特性。3）高陡边坡生物结皮覆盖可显著削弱土壤径流侵蚀量，且减蚀效应随坡度增大和降雨强度提升呈增强趋势。在80、100、120 mm/h雨强下，结皮覆盖坡面径流侵蚀量显著低于无结皮覆盖坡面，平均降幅分别为63.3%、46.3%、64.5%；在40、60、80、100、120 mm/h雨强下，55°、65°、75°坡面的径流侵蚀量分别平均降低40.3%、62.1%、63.6%。结论生物结皮可通过表面覆盖、改善土壤理化性质、增加土壤抗蚀性并影响坡面径流水动力学特性等途径，显著降低降雨诱发的黄土高陡边坡侵蚀，对黄土丘陵沟壑区自然和人为边坡具有良好的防护作用，可广泛用于黄土高陡边坡侵蚀防控和生态修复。",
