福建省福州市叶蜡石矿区废弃地土壤肥力状况分析

Analysis on the Soil Fertility Status at the Deserted Pyrophyllite Mines of Fuzhou Municipality,Fujian Province

福州市叶蜡石矿的保有储量居全国首位,矿山开发使得矿区地质环境遭受破坏,地被几乎丧失殆尽。对福州市晋安区宦溪镇峨嵋叶蜡石矿区进行土壤和植被调查、试验分析,结果表明:矿区废弃地土壤酸性较强,土壤碱解氮、速效磷、速效钾、有机质含量都较自然植被下土壤有非常明显地降低,矿区废弃地有一定的自然恢复能力,但相当缓慢,后期需要采取人工干预措施。

Recoverable deposits of Pyrophyllite mine of Fuzhou Municipality top the list in China. The exploration of the mines destroyed the geological environment and almost the ground vegetation. The investigation and experimental a- nalysis was conducted to the Emei Pyrophyllite mines of Huanxi Township, Jin＇ an District of Fuzhou Municipality. The result shows that the soil acidity is stronger in the deserted mining area, with the obvious decrease of content of al- kali- hydrolyzable nitrogen, rapidly available phosphorus, available potassium and organic matters comparing with those in the soil covered by the natural vegetation. The deserted mining area has certain natural recovery ability at a fairly slow step, that need the manual intervention measures at late state.
