摘要
文章以辽宁大石桥市官屯镇大岭村滑石矿为例,分析了滑石矿未损毁和已损毁前后的土壤养分和物理性质变化情况,分析结果表明,土地损毁后所剥离的表土堆场的土壤化学养分较之未损毁前明显下降,土壤物理性质变差。因此,在土地复垦中可通过施用有机肥和复合肥改善土壤的物理性质和养分状况,借以提高植被恢复的成活率和保存率。
Taking an example of talc at Daling village of Guantun town in Dashiqiao City of Liaoning Province,changes of soil nutrients ＆ physical properties for undamaged ＆ damaged talc were analyzed. Analysis result shows that soil chemical nutrients in yard of topsoil after soil being destroyed decrease significantly than that of the soil undestroyed;soil physical properties deteriorate. So,soil nutrient status and soil physical properties were improved by increasing the application of organic fertilizer and compound fertilizer for improving survival rate and preservation rate of vegetation restoration.
