摘    要:为了深入探讨黄土高原沟壑地区小流域水沙运动及水土流失规律,采用平凉市纸坊沟流域50a的降水、径流、泥沙观测资料和成果,建立数据库,采取数理统计、矩阵计算、分段对比、相关分析等方法对黄土高原沟壑区典型小流域纸坊沟流域的水沙特性及水土流失特点进行了分析,研究了流域降水、径流、泥沙基本特性及其变化规律和水土流失主要影响因素及其相互关系,建立了流域土壤侵蚀流失量与主要影响因素间的单因子数学模型,为同类地区小流域水土流失状况分析和径流、泥沙及水土流失量估算分析确立了简便方式。该文从其研究成果中提炼出了纸坊沟流域水土流失主要影响因子及其变化对土壤侵蚀流失量减少的影响程度以及土壤侵蚀流失量与主要影响因素间的单因子数学模型。

关 键 词:水土流失  影响因素  数学模型  相关关系
