摘要
矿区废弃地造成的环境污染、生态破坏问题,已经严重威胁到了生态经济的可持续发展和人类的生存。矿区废弃地实施生态恢复是解决矿区生态环境的重要措施之一,通过植被恢复来改善土壤质量是矿区废弃地生态恢复的最佳策略。从土壤物理特性(含水量、容重、孔隙度)、化学特性(氮、磷、钾等)和土壤生物学活性(微生物量、土壤酶活性、土壤动物)方面阐述了土壤特性对磷矿废弃地植被恢复过程的响应,为阐明磷矿废弃地的土壤特性响应机理提供理论依据;并提出今后该领域的研究建议:采用土壤动物作为土壤健康的生物指示标准,加强研究植被恢复过程中土壤动物对土壤质量变化响应机理,以便更好地探索昆阳磷矿废弃地植被恢复后土壤质量演变过程中土壤动物群落动态变化及其与植被关系。
The environment pollution and ecological destruction caused by mining wasteland have made serious crisis to the ecologically sustainable economic development and human life. Ecological restoration is one of the important measures to solve the ecological environment of mining areas,and the revegetation is the key to the ecological restoration of mining wasteland. This paper summarized the changes of soil physical properties（water-holding,soil bulk density,and porosity）,chemical properties（nitrogen,phosphorus and kalium）,and biological properties（microbial biomass,enzyme activities,and nematode）during the progress of vegetation restoration,aimed to elucidate the responses of soil properties to phosphate mine wasteland. Some suggestions for further researches in this field,e g,soil fauna as biological soil health indicator,to strengthen the responses of soil fauna to the change of soil quality,in order to promote the dynamic changes of soil fauna community and its relationship with soil quality vegetation after Kunyang phosphate revegetation.
