| 摘 要： | 通过在典型的红壤坡地建立标准径流小区进行试验，采用统计学方法对不同水土保持措施下地表径流量和土壤侵蚀量的变化情况进行了定量分析。研究结果表明，提高植被覆盖度和辅以必要的工程措施是南方红壤坡地水土保持的有效途径，尤其是在水平梯田裸露的梯壁上植草后，其拦蓄地表径流和控制土壤侵蚀的能力分别提高22．5，30．62倍。

| Abstract: | The experiment was conducted with standard runoff treatments. Quantitative analyses of the runoff coefficient and the amount of soil erosion under different soil and water measures were made by means of statistical methods. Results showed that it was an effective approach to raise the level of vegetation coverage with necessary engineering measures supplemented for soil and water conservation in sloping land of red soil. Especially after planting grass on level bench terrace wall, the capability for decreasing runoff and the capability for controlling the amount of soil erosion increased 22.5 and 30.62 times, respectively. |
