- Abstract
In standard runoff plots with 10° and 15° slope croplands in purple soil areas, the paper studies influences of plant hedge on slope water and soil loss for slope croplands in purple soil areas under the natural rainfall conditions comprehensively and analyzes control actions of plant hedge’s intervals arrangement on agricultural non-point source pollution. Change features of erodibility K-factor and clay content are basically consistent. Generally speaking, plant hedge plays a role on erodibility K-factor and reflects as follows: vetiver grass plant hedge>new horse tamarind, 10°>15°. Erodibility K-factor has a significant positive correlation with soil sand grain content and microaggregate grain size<0.002mm dispersion coefficient. The correlation coefficients are 0.980 and 0.836, respectively. It has a significant negative correlation with soil particles, clay particles, organic carbon content, degree of aggregation and fractal dimension of soil particles, and the correlation coefficients are -0.925, -0.833, -0.787, -0.716 and -0.807, respectively. Soil sand grain content, particles, clay particles, organic carbon, organic content and degree of aggregation have the closest correlation with erodibility K-factor. Moreover, the high-low content of organic matter and clay content are effective index reflecting strong or weak soil anti-erosion ability.
