Abstract

以内蒙古准格尔旗永利露天煤矿排土场边坡为研究对象,采用野外放水冲刷的试验方法,研究不同放水流量
下(5,10,15,20L·min-1)沙打旺(Astragalus adsurgens Pall)条播、沙柳(Salix cheilophila)方格+沙打旺撒播、
沙打旺撒播、草木樨(Melilotus suaveolens Ledeb)撒播和紫花苜蓿(Medicago sativa)撒播等植被措施对边坡径流产
沙的影响。结果表明:植被措施坡面入渗率较裸地增大7.55%~192.19%,沙打旺条播和沙柳+沙打旺撒播的入
渗率随放水流量的增加而增大,而裸地、沙打旺撒播、草木樨撒播、紫花苜蓿撒播入渗率随着放水流量的增加先增
大后减小再增大。植被措施坡面的径流量较裸地减少0.97%~90.49%。放水流量为5~15L·min-1时,沙打旺
减水效果最好,流量为20L·min-1时,撒播紫花苜蓿减水效益最高。各植被措施的径流量与放水流量均呈显著的
幂函数关系。植被措施坡面的产沙量较裸地减小63.45%~93.27%,撒播紫花苜蓿的减沙效果最佳,条播沙打旺
次之。各植被措施的产沙量与放水流量均呈显著幂函数关系。结果可为风蚀水蚀交错区露天煤矿排土场边坡植
被防护措施的优化配置提供科学指导。

Other Abstract

A scouring experiment was carried out to investigate the effects of discharge flow(5,10,15,20
L·min-1)on the processes of runoff and sediment yielding with different plantation rehabitation methods
(drilling Astragalus adsurgens Pall;broadcasting Salix cheilophila and Astragalus adsurgens Pall;
broadcasting Astragalus adsurgens Pall;broadcasting Melilotus suaveolens Ledeb;broadcasting Medicago
sativa)in Yongli open pit mine,Inner Mongolia.Results showed that the average infiltration rate of side
slope with plantation was 7.55%~192.19%higher than the bare land.The runoff volume with plantation
was 0.97%~90.49%lower than the bare land.The water reducing benefit of Medicago sativa was the
best under the flow of 20L·min-1,and at other flow rates,the water reducing benefit of Astragalus adsurgens
Pall was the best.The runoff volume was found to be a power function of discharge flow.The
sediment yield with plantation was 63.45%~93.27%lower than the bare land.The sediment reducing
benefit of Astragalus adsurgens Pall was better than Medicago sativa.The sediment yield was found tobe a power function of discharge flow.Results can provide scientific guidance for vegetation measures of
dump side slope protection in wind-water erosion region
