摘要:
基于松华坝水源区2008年自然降雨监测数据，采用径流小区法对坡面地表径流中磷素流失进行分析；结果表明：不同土地利用类型下，坡面地表径流磷素流失量与径流量、产沙量基本一致；人工次生林地（云南松纯林）在控制地表磷素流失上有显著效果；当地传统农业模式下的烤烟、玉米栽植，地表径流磷素流失显著，施肥后的1～3次降雨是磷素流失的主要时期。转变当地农业结构，扩大经济林地面积，减少人为活动对地表的影响是解决坡面地表磷素流失的关键。
Abstract:
Based on the natural rainfall data of the headwaters, the phosphorus losses of slope runoff were analyzed. The results showed that the phosphorus loss of slope runoff was consistent with runoff and soil erosion and the plantation has significant effects on control of phosphorus loss. In local traditional agricultural mode of flue-cured tobacco and corn planting, the significant phosphorus loss happened the 1～3 times in the rainfall period after fertilization. Changes in local agricultural structure, expansion of economic forest area, reduction of the impact of human activities on the ground surface are the keyes to solve the problem of phosphorus loss along with slope runoff.
