| 摘要: 试验研究红壤坡地果园水平梯田梯壁植草等8种处理水土保持效益结果表明，不同处理间有显著差异，与全园裸露(对照)相比水平梯田梯壁植草水土保持效果最佳，其径流系数平均比对照减少89．7％，土壤侵蚀量控制基本达100％，其他各处理均有不同程度防治水土流失的效果。生草栽培处理的土壤理化性质均有所改善。 |

| Abstract: This thesis has probed the benefits of soil and water conservation by eight different treatments on sloping land orchard of red soil．The resuIts show that compared with bare soil(CK)，planting Bahia grass on level bench terrace wall is the most effective method to conserve water and soil．It reduces the average runoff coefficient by 89．7％ and the amount of soil erosion almost 100％ ．Other treatments also result in some positive effects．Furtherm ore，the physical and chem ical properties of soil with sod culture are improved respectively． |
