中文摘要 采用野外实地放水冲刷的试验方法,对岷江上游干旱河谷区龙坝沟流域不同土地利用方式(灌木林地、荒草地、耕地和裸地)下土壤抗冲性进行测试研究,分析了土壤侵蚀产沙相关因素。结果表明:不同土地利用方式下土壤抗冲系数均随冲刷时间延长呈波状上升变化趋势;土壤的抗冲性从大到小依次为:荒草地、小麦耕地、灌木林地、玉米耕地、裸地;土壤抗冲系数与粉粒体积分数呈显著负相关(相关系数为-0.992,P<0.01),与砂粒体积分数呈显著正相关(相关系数为0.925,P<0.01)。
英文摘要In order to provide scientific and theoretical basis for control of water and soil loss of slope,soil
anti-scourability for different land uses ( shrub land,waste grassland,cultivated land and bare land) in
Longbagou basin,the dry valley of upper Minjiang River was studied by the flume experiment,and soil
erosion and sediment yield characteristic and its influencing factors were discussed. The results showed
that the anti-scourability of surface soil under different land use patterns increased and assumed wavy
variation along with scouring time; the anti-scourability followed the order of waste grassland,wheat
land,shrub land,corn land,bare land; soil anti-scourability values and silt content has a significant
negative correlation ( r = - 0. 992,P < 0. 01) ,and sand content has a significant positive correlation
( r = 0. 925,P < 0. 01) .
