摘　　要：为了更深入了解和阐释人工恢复措施干预后退化土壤理化性质的变化规律,本研究选择涉县铁矿废弃地作为研究区域,以当地普遍采用的2种植被恢复模式为研究对象,分析比较不同植被恢复模式修复改良效果差异。结果表明:连翘模式下土壤pH值则较CK下降2.970%,有机质增加185.533%,土壤全氮含量增加177.528%,全磷减少26.601%,全钾减少14.564%,碱解氮含量增加177.235%,速效磷增加36.046%,速效钾增加0.828%;铁、铜、锌、钼元素含量较CK都分别有所增加,锰元素减少。花椒模式下土壤pH值较CK下降1.306%,全氮含量减少44.944%,全磷增加10.890%,全钾减少2.768%。碱解氮含量减少67.209%,速效磷增加1957.245%,速效钾减少15.097%;锰、铜、钼元素含量较CK分别有所增加,而铁、锌元素含量则减少。2种恢复模式对于退化土壤矿质养分元素含量提升基本表现出改善和促进作用。本研究中13项化学性质指标,其中9项连翘模式数值高于花椒模式,基本表明连翘模式在此种立地条件和退化生态系统类型下的适应性、功能性要优于花椒模式。In order to gain a deeper understanding and interpretation of the changes and development patterns of physical and chemical properties in degraded soil after intervention with artificial restoration measures,this study selected the abandoned iron mine land in Shexian county as the research area,and took the commonly used two vegetation restoration models as the research objects to analyze and compare the differences in the restoration and improvement effects of different vegetation restoration models.The results showed that under the Forsythia suspensa mode,the soil pH value decreased by 2.970%compared to the CK,organic matter increased by 185.533%,total nitrogen content increased by 177.528%,total phosphorus decreased by 26.601%,total potassium decreased by 14.564%,alkaline nitrogen content increased by 177.235%,available phosphorus increased by 36.046%,and available potassium increased by 0.828%.The content of iron,copper,zinc,and molybdenum elements has increased compared to CK,while the content of manganese element has decreased.Under the Sichuan pepper mode,the soil pH value decreased by 1.306%compared to CK,the total nitrogen content decreased by 44.944%,the total phosphorus increased by 10.890%,and the total potassium decreased by 2.768%.The alkaline hydrolyzed nitrogen content decreased by 67.209%,the available phosphorus increased by 1957.245%,and the available potassium decreased by 15.097%.The content of manganese,copper,and molybdenum elements increased compared to CK,while the content of iron and zinc elements decreased.Two restoration modes have shown improvement and promotion effects on the increase of mineral nutrient element content in degraded soil.In this study,there were 13 chemical property indicators,among which 9 showed higher values in the Forsythia suspensa model than in the Sichuan pepper model,indicating that the adaptability and functionality of the Forsythia suspensa model are better than those of the Sichuan pepper model under this site condition and degraded ecosystem type.
