Abstract

根据东北沟小流域观测裸地、等高耕种、水平阶等 3 种措施径流小区的径流量和泥沙量资料,研究不同
措施下径流泥沙与降雨等因素的相互关系,采用典型相关分析法分析不同措施下影响土壤侵蚀的主要因子。
结果表明,在裸地和等高耕作措施下,径流深在土壤侵蚀特征因子中起主要作用,而在水平阶措施下,土壤流
失模数在土壤侵蚀特征因子中起主要作用。不同措施下土壤侵蚀影响因子不同,在裸地和水平阶措施下,可
以通过降雨量、雨强和雨前土壤含水量等土壤侵蚀影响因子来预测径流深和土壤流失模数,而在等高耕作措
施下,用降雨量、雨强、降雨侵蚀力等土壤侵蚀影响因子预测土壤侵蚀特征因子更为准确。

Other Abstract

 The runoff and sediment of three approaches (bare land,contour cultivation,level terrace) in the
northeast gully watershed were observed. The relationship between runoff,sediment and rainfall and other fac-
tors were studied. The Canonical Correlation Analysis method were used to analysis the soil erosion characteris-
tics. Under the bare land and contour tillage approaches,runoff depth played a main role in theⅠtypical vari-
able. Under the level terrace measure,soil erosion modulus played a main role in theⅠtypical variable. Re-
dundant index analysis showed that under the approaches of bare land and level terrace,theⅠtypical variables
in soil erosion characteristic factor could be well predicted by erosion impact factors,but the impact factors of
soil erosion under the three measures were not predicted well by erosion characteristics factors. In the bare
land and level terrace,the rainfall,rainfall intensity and antecedent soil moisture and other erosion factors
could predict runoff and soil erosion modulus. While in high tillage,soil erosion factors to predict the charac-
teristics of soil erosion factor is more accurate with the rainfall,rainfall intensity,rainfall erosion force
