摘  要：
随着采矿业的迅速发展,矿区原有的生态系统遭到破坏,使得矿区生态环境的脆弱性凸现。以生态脆弱的许村煤矿区为研究区域,利用紫花苜蓿作为先锋植被,应用腐植酸肥料改良土壤,对矿区损毁土地进行土地复垦与生态重建。研究结果表明,相对于常规施肥处理,施用腐植酸肥料的土壤理化性状明显改善,土壤容重降低,土壤阳离子交换量和土壤有机质提高,促进土壤速效氮、磷、钾营养元素的释放。腐植酸肥料还能提高紫花苜蓿产量。本研究结果显示,腐植酸肥料在土地复垦与生态重建过程中,有良好的效果。

摘  要：
With the rapid development of mining industry, the original ecosystem is destroyed in mining area, which makes the ecological environment very fragile. In this paper, selected the ecological fragile mining regions of Xucun as the study area, and used alfalfa as the pioneer vegetation, the application of humic acid fertilizer in land reclamation and ecological reconstruction were studied. The results showed that, compared with the conventional fertilization treatment, applying humic acid fertilizer could improve soil physical and chemical properties evidently, decrease soil bulk density, enchance soil cation exchange capacity and content of soil organic matter, and promote the release of soil available nitrogen, phosphorus and potassium. In addition, applying humic acid fertilizer could increase the yield of alfalfa. In conclusion, Humic acid fertilizer should have broad application prospect in the field of land reclamation and ecological reconstruction.
