- 摘要:
- 结合野外调查和室内分析，对黑岱沟矿区排土场不同土地复垦方式下的土壤性质进行了研究。结果表明：除土壤容重和pH值外，不同复垦方式土壤有机质、硝态氮、铵态氮、速效磷、团聚体、脲酶和蔗糖酶含量在整体上较未复垦地土壤有所提高；研究区土壤有机质、硝态氮、脲酶、蔗糖酶等指标间呈显著或极显著正相关，可作为综合指数来表征土壤质量的好坏；以林地为主的混合复垦方式土壤恢复指数较高，表明林地混合复垦方式对黑岱沟矿区排土场土壤修复有重要意义。
- Abstract:
- Combining field investigation with laboratory analysis, we studied the soil properties under land reclamation conditions in different ways in Heidaigou mine dump, analyzed the relationship between land reclamation methods and soil quality. The results showed that soil organic matter, available phosphorus, nitrate nitrogen, urease, invertase and other indicators were significantly different under different types of reclamation. There was the significant correlation among these indexes. The indexes can be used as a comprehensive indicator to characterize the soil quality. And the soil recovery index of poplar-seabuckthorn reclamation type was the highest, showing that seabuckthorn-poplar reclamation has the important significance for soil amelioration in Heidaigou area.
