| 摘 要： | 在山西潞安矿区王庄煤矿北矸石山进行了土壤抗冲性试验,对矸石山坡面植物根系的土壤抗冲性进行了研究.研究表明:(1)根系长度随根系径级的增大而不断减小,表明土壤中以小径级根系为主,且不同径级根系在土壤中的分布存在较大的空间变异性;根系生物量随根系径级的增大总体上呈下降趋势,即矿区坡面土壤中小径级根系分布较大根系多;(2)根...

| Abstract: | The soil resistance to erosion test was carried on Wangzhuang north coal gangue dump in Lu＇an in Shanxi.Soil resistance to erosion of slope plants roots on the coal gangue dump was studied.It concludes that： ①the root length continuously decrease with the increase of root diameter level which showed small-diameter root is mainly in the soil;distribution among different diameter root in the soil have greater spatial variation;root biomass decrease with the increase of root diameter as a whole,namely distribution of small-diameter are more than that of big-root in the soil of slope in the mining area;② protection effect of root to soil on the slope surface is remarkable;effect of improving soil erosion resistance is remarkable by superficial roots with rich slopes under the same erosion strength time of runoff;③soil erosion resistance of slope is more more stronger with the increase of rainfall duration. |
