| 摘 要： | 研究水土保持综合治理时小流域侵蚀产流量和次降雨径流过程的影响.以黄土丘陵沟壑区第Ⅲ副区内治理小流域桥子东沟和未治理小流域桥子西沟为对象,分析水土保持综合治理不同阶段小流域侵蚀产流量年际变化和次降雨径流过程.结果表明:桥子东沟产流次数较桥子西沟减少了42.86%,年径流模数为桥子西沟的5%～63%;桥子东、西沟的多年平均径流系数分别为1.80%和4.03%;桥子东、西沟年径流深比值略有下降,治理后期在0.6以下.桥子东沟在治理后期的次降雨起流和洪峰流量的出现都晚于桥子西沟;桥子东、西沟次降雨洪峰流量、洪水历时比值不断下降,治理后期分别为0.41和0.61.水土保持综合治理的实施有效减少了治理流域的侵蚀产流量,对次降雨径流过程影响很大.
