胶质芽孢杆菌与苜蓿根瘤菌双接种对排土场紫花苜蓿生长和土壤性质的影响

open access: yesShuitu Baochi Xuebao, 2021
为了明确胶质芽孢杆菌和苜蓿根瘤菌在矿区排土场复垦中的协同作用,以矿区排土场土壤作为基质进行盆栽试验,设置两菌单接种处理、双接种处理及对照,其中胶质芽孢杆菌和苜蓿根瘤菌用量分别为1.50%和0.25%,测定紫花苜蓿产量指标、叶片生理指标、土壤速效养分含量和土壤微生物指标。结果表明,接种胶质芽孢杆菌和苜蓿根瘤菌的各处理均能显著提高紫花苜蓿的产量指标,其中以双接种处理效果最优,将生物量和结瘤量分别比对照显著提高110.27%和124.32%;在生理指标方面,双接种处理效果低于单接种处理,未表现出协同作用 ...

天然地形和人工沙棘风障对排土场平台植被恢复的影响

open access: yesShuitu Baochi Xuebao, 2001
以霍林河露天煤矿为例 ,通过对排土场不同地段植被的观察、野外小区实验和室内分析的方法 ,调查研究了天然地形风障以及人工沙棘风障对半干旱地区露天煤矿排土场平台植被恢复状况的影响。研究结果表明 ,地形与人工沙棘风障不仅起到防风作用 ,还可以改善土壤理化性质 ,促进其它植物的生长 ,防治水土流失 ,加速排土场的植被恢复与生态重建的进程。

黄土区大型露天矿排土场岩土侵蚀及其控制技术的研究

open access: yesShuitu Baochi Xuebao, 1994
该文以平朔安太保露天矿为例,探讨了岩土侵蚀的形式,分布及成因,岩土侵蚀的危害和潜在危险。首次提出排土场岩蚀控制的方针为“以排为主,排蓄结合,调节水分,增强整体稳定性,迅速复垦,恢复植被,建立生物工程相结合的控制体系”,控制技术包括基底处理,平盘边坡防护,滑坡崩塌危险区控制及排土复垦工艺。

不同近地表水文条件下矿山弃土对土壤细沟可蚀性的影响—以攀枝花盐边县龙蟒矿山为例

open access: yesShuitu Baochi Xuebao, 2016
以攀枝花盐边县红格龙蟒矿山李家河排土场、未被开采过的矿区灌草地和耕地3种土壤为研究对象,基于土壤水蚀预报模型(WEPP)中细沟侵蚀模型,采用100,200,300,400,500,600 ml/min的流量对灌草地、耕地和矿山排土场土壤分别进行排水、饱和以及渗流状态下的冲刷试验,查明其可蚀性(Kr)的变化。结果表明:(1)径流剪切力与土壤剥蚀率之间存在较显著的指数关系(P<0.01);(2)流量与土壤剥蚀率之间存在较为显著的指数关系(P<0.01),土壤剥蚀率随流量的增加呈指数形式增加;(3)在排水 ...
