摘要：研究矿区排土场不同灌木林土壤养分的变化特征,定量评价不同固沙灌木林土壤质量,对排土场合理选择固沙树种和指导生态修复具有重要的现实意义。选取种植沙棘、拧条、巨菌草、欧李、蛋白桑、文冠果6种灌木的固沙地与裸地(BS)进行对照,通过分析土壤化学性质并结合主成分分析与土壤质量指数法,定量评估了不同灌木对土壤质量的改良效应。结果表明:6种灌木林土壤的有机质含量均高于对照组,对土壤养分的影响呈现出各自特点。巨菌草土壤的pH值、全磷以及速效磷含量均达到最高水平;拧条土壤在全氮和速效钾含量上表现突出;欧李土壤在碱解氮和全盐量方面表现最优;沙棘土壤的全钾含量最高。相关性分析揭示,土壤化学性质之间存在显著的正相关性。基于土壤综合质量指数的评估结果,拧条、欧李和巨菌草在土壤质量恢复方面展现出了卓越的性能,表现显著优于其他灌木。这对满来梁矿区排土场土壤质量的恢复具有重要指导意义,表明这3种灌木林是恢复该区域土壤质量的最佳选择。通过土壤综合质量指数计算结果可知,土壤质量评价综合得分从大到小排序为拧条、欧李、巨菌草、沙棘、文冠果、蛋白桑、BS,拧条、欧李和巨菌草最有利于矿区排土场土壤质量恢复。
Studying the variation characteristics of soil nutrients in different shrub plantations at the mine dump site and quantitatively evaluating the soil quality of various sand-fixing shrub stands hold significant practical implications for the rational selection of sand-fixing species and ecological restoration guidance.Six shrub plantations(Hippophae rhamnoides,Caragana korshinskii,Pennisetum giganteum,Cerasus humilis,Morus alba var.multicaulis,and Xanthoceras sorbifolium)were selected for comparison with bare soil(BS).By analyzing soil chemical properties combined with principal component analysis(PCA)and the soil quality index(SQI)method,the improvement effects of different shrubs on soil quality were quantitatively assessed.Results showed that the organic matter content in all six shrub plantation soils exceeded that of the control group,with distinct characteristics in soil nutrient enhancement:Pennisetum giganteum exhibited the highest pH,total phosphorus,and available phosphorus levels.Caragana korshinskii demonstrated superior performance in total nitrogen and available potassium content.Cerasus humilis showed optimal results in alkali-hydrolyzable nitrogen and total salt content.Hippophae rhamnoides achieved the highest total potassium content.Correlation analysis revealed significant positive relationships among soil chemical properties.Based on the comprehensive soil quality index(SQI)evaluation,Caragana korshinskii,Cerasus humilis,and Pennisetum giganteum exhibited outstanding performance in soil quality restoration,significantly outperforming other shrubs.This finding provides critical guidance for soil recovery at the Manlailiang Mine dump site,identifying these three species as optimal choices for soil quality rehabilitation.The SQI rankings in descending order were:Caragana korshinskii,Cerasus humilis,Pennisetum giganteum,Hippophae rhamnoides,Xanthoceras sorbifolium,Morus alba var.Multicaulis,BS,confirming the superior efficacy of the top three shrubs in restoring soil quality at mine dump sites.
