    铜尾矿库土壤修复效应及周边植被恢复模式研究

    Study on Soil Remediation Effect of Copper Tailings Pond and Surrounding Vegetation Restoration Model

    • 摘要: 基于山西省南部某铜尾矿库出现的土壤贫瘠和金属污染问题,采用经典样方法共设置36个20 m×20 m的调查样方,进行植物多样性和重要值分析,针对土壤理化性质分别提出不同的修复方法,运用ArcGIS绘制营养元素和污染元素的空间分布,进行修复效果检验,并结合AHP层次分析法进行生态适宜性评价。结果表明:研究区内灌草层较乔木层植物更加丰富,且重要植物以玉米、苜蓿、茼蒿、雏菊为主;松土、深翻、客土和植物覆盖对于土壤物理性质的改善具有明显效果,而种植常年生长且落叶多的豆科植物可明显提高矿区土壤的有机质、全氮、全磷等营养物质含量;种植红三叶对于铜金属污染具有良好的治理效果。研究区范围内采样和排土场宜草、西部区域宜林、南部和东部区域宜耕。本研究为今后因地制宜生态恢复提供科学依据,并为其他类似矿区提供参考价值。

       

      Abstract: Based on the poor soil and metal pollution of a copper tailings pond in southern Shanxi Province, a total of 36 survey plots of 20 m × 20 m were set up using the classic sample method to analyze plant diversity and important values, respectively, according to the physical and chemical properties of the soil. Propose different restoration methods, use ArcGIS to map the spatial distribution of nutrient elements and pollution elements, test the restoration effect, and evaluate the ecological suitability combined with the AHP analytic method. The results show that the shrub and grass layer in the study area is more abundant than the arbor layer, and the important plants are mainly corn, alfalfa, chrysanthemum and daisy; loose soil, deep plowing, extra soil and plant mulching have obvious effects on the improvement of soil physical properties , And planting legumes that grow all the year round with many deciduous leaves can significantly increase the organic matter, total nitrogen, total phosphorus and other nutrient content of the soil in the mining area; And planting red clover has good control effect on copper pollution. sampling and dumping sites within the study area are suitable for grass, the western region is suitable for forestry, the southern and eastern regions The area is suitable for farming. This study will provide a scientific basis for ecological restoration in the future according to local conditions and provide reference value for other similar mining areas.
