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
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 ...
