基于3个种植植物篱的试验小区和2个对照小区在3次降雨条件下的土壤侵蚀状况，将降水、坡度坡长、植物覆盖类型、土壤可蚀性 K 值作为影响因子输入，利用 Markov 模型和 CA 相结合的方法分别对5个小区的水土流失情况进行了模拟预测，并对结果以及引起误差的原因进行了分析。观测和模拟的结果表明，植物篱可以显著地减少坡面土壤流失量，并且不同植物篱作用不同，香根草的水土保持作用优于新银合欢，同时香根草在10°小区的作用大于它在15°小区的作用。

Based on the erosion of three test plots with planted hedgerows and two control plots in three rainfall conditions,we build a CA-Markov model with input factors of the precipitation,gradient,slope length,vegetation cover type,and soil erodibility K value to simulate and forecast the erosion of the five plots and analyze the results as well as the causes of errors. The results show that hedgerows can signifi-cantly reduce the amount of slope soil loss,and the effect of vetiver,which is better in 10° text plot than that in 15° text plot,is better than that of new leucaena.
