| 摘 要： | 文章以鞍山矿区自然植被恢复条件下的铁矿矸石山为研究对象,通过野外调查、实地观测和室内分析测定,研究了铁矿矸石山土壤物理特征.研究表明:土壤容重随着废弃年限的增加而减小,废弃同期的阳坡由于风化滞后,其土壤容重大于阴坡.土壤自然含水量、饱和含水量、毛管持水量、田间持水量、总孔隙度、毛管孔隙度随废弃年限的增加呈同步增长的态势...

| Abstract: | Taking the iron gangue mountain under the condition of natural vegetation restoration in Anshan mining area as an example,the paper studies soil physical property of iron gangue mountain through the field investigation,field observation and laboratory analysis.The study shows that the soil bulk density decreases along with dumping years and in sunny slope is higher than in shady slope because of weathering in the same dumping period.It is shows the soil structure is better that the soil moisture,capillary c... |
