| 摘 要： | 为研究煤矿排土场植被恢复与重建过程中植被与土壤的关系,以阜新海州排土场为例,应用DCCA排序分析方法研究植被和土壤环境关系,排序图显示第一排序轴与pH和速效K呈负相关关系,而与速效P、速效N、有机质、全N、电导率呈正相关关系,第二排序轴与速效P、电导率和速效N呈正相关,与其他土壤因子负相关.植被种类的分布象限表明刺槐(Robinia pseucdoacacia)排土场较为恶劣的土壤环境中生长良好.综合分析认为:在阜新海州排土场植被恢复初期适合种植的乔木物种为刺槐(Robmia pseucdoacacia),随着植被恢复和停止排矸年限延长,土壤环境改善,植被种类增多,猪毛蒿(Artemisia scoparia)等草本植被生长良好.

| Abstract: | In this paper,the relations between plant and soil were studied at Haizhou mine waste dumps in Fuxin,Liaoning,using Detrended Canonical Correspondence Analysis(DCCA) method.The ordination diagram showed that the first Axis had a negative correlation with available K and pH and a positive correlation with available P,available N,conductivity,total N and organic matter.The second Axis positively correlated with available P,conductivity,available N,and negatively correlated with total N,organic matter,availabl... |
