摘　　要：对湘潭锰矿废弃地的土壤特性与植物生长调查进行的分析表明:与非矿渣废弃地相比,锰矿废弃地土壤物理结构极不均匀,大都不适宜植物生长发育;土壤呈中性,N、P含量较高,具备植物生长所必需的养分;但土壤中微量元素含量大都严重超标,往往会使植物中毒,甚至杀死植物。建议在生态恢复时首先覆土改良土壤结构,其次选择高抗性的植物品种,特别是耐Mn、Zn、Pb的植物品种。The investigation and analysis on soil characteristic and plant growing on abandoned land of polianite in Xiangtan show that comparing with non-slag abandoned land,the physical structure of abandoned land of polianite is extremely uneven and the most of land is not suitable for plants growing;pH value of soil is neutral,N and P contents higher and possess the necessary nutrient for plants growing and;the majority of microelement contents seriously exceed criterion,make plants easily poisoned or even kill the plants.It suggests firstly to earth up for improving the soil structure during ecological rehabilitation,and then selects the plant variety of high resistance.
