通过模拟实验比较了河流两侧坡面采伐与非采伐森林对流域暴雨径流的影响 ,并建立了模型 .结果表明 ,森林坡面地表径流的出流时间和峰现时间均比采伐坡面迟缓 ,径流历时延长 ,峰值流量和地表径流总量较低 .坡度越大 ,影响越显著 .当雨强 1.98mm·min-1,降雨量 10 8.8mm时 ,15°两侧森林坡面比其采伐坡面峰值流量削减 5 % ,径流总量降低 4% . The simulation experiments were conducted to compare the effect of the harvested and non-deforested slopes on both sides of the river on the runoff stormwater runoff and the model was established.The results show that both the outflow time and the peak emergent time of the surface runoff on the forest slope are slower than those of the harvesting slope, When the rainfall intensity is 1.98mm · min-1 and the rainfall is 10.88mm, the slope of the forest on both sides of 15 ° is higher than that of the cutting slope 5% reduction in peak surface flow and 4% reduction in total runoff.
