Shuitu Baochi Xuebao, 2008 土壤入渗性能是最基本的土壤物理特性之一。复垦区土壤的结构组成复杂,入渗特性有别于非矿区土壤。本文以神府东胜煤田马家塔复垦区为研究对象,利用圆盘入渗仪分别测定了复垦区乔木、林地、荒地、灌木林地和草地的土壤入渗特性,用经典统计学方法对复垦区土壤入渗性能的空间变异性进行了分析。实测结果表明,不同土地利用方式下的土壤入渗特性有较大的差异;在测定范围内,乔木林地、荒地、草地和灌木林地的稳定入渗率均表现出0 cm>—3 cm>—15 cm的规律性,其中草地稳定入渗率随吸力的变化更明显。研究表明 ...

Advances in research on technologies for large-scale coal gangue utilization for green mine construction [PDF]
BackgroundThe coal gangue, a solid waste, features high production and a continuous increase in the amount piled in China. The long-term piling up of coal gangue will cause the waste of land resources and environmental pollution in mining areas.

生物炭与有机肥、无机肥配施对采煤塌陷区复垦土壤理化性状的影响
Shuitu Baochi Xuebao, 2017 为了研究施用生物炭对采煤塌陷复垦土壤的熟化效果，以山西省晋城市采煤塌陷复垦区土壤为研究对象，连续3年采用生物炭与有机肥、无机肥配施等方式研究其对复垦土壤主要理化性状的影响。结果表明：不同施肥处理均不同程度改善了土壤的理化性状,有机肥配施生物炭处理明显降低了复垦土壤容重（降幅10%），提高了土壤孔隙含水率（增幅7.14%），但对土壤pH影响不明显。有机肥处理和无机肥处理的土壤全氮、全磷含量差异不显著；无机肥配施生物炭处理与单施无机肥处理相比，速效磷增加了8.33%，速效钾增加了6.34%，增幅较明显 ...

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
Shuitu 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 ...
