海州露天矿土地复垦示范区土壤综合质量评价

Evaluation on Comprehensive Quality of Soil in Land Reclamation Demonstration Area in Haizhou Open-Pit Mine

为有效地治理和改善矿区恶劣生态环境,使废弃的土地资源得以充分利用,通过对阜新海州露天矿土地复垦示范区土壤有机质、全N、有效P、速效K、EC、pH值、含水量、容重、紧实度等指标进行测定,开展了复垦土壤质量综合评价。结果表明:不同复垦示范区土壤质量差异较大,沙打旺、冰草示范区土壤质量最好;杨树、油松示范区次之;耕地、侧柏示范区土壤质量较差。

In order to effectively control and improve the poor ecological environment and fully utilized the waste land resources,the soil organic matter,the total N,the available P,the available K,EC,the pH value,the moisture content,the bulk density and compaction in Land Reclamation Demonstration Area in Haizhou open-pit mine of Fux-in City were determined.Comprehensive quality of soil is evaluated.Result shows that:the differences of soil quality in reclamation demonstration area is significant;the quality of soil for Astragalusadsurgens,Agropyroncristatum in the Demonstration Area are optimal;the Demonstration Area of Populus spp.&Pinus tabulaeformis is the sec-ond;the quality of soil in the Demonstration Area of farmland &Platycladus orientalis is poor.
