内蒙古伊金霍洛旗煤矿开采对土壤性质影响评价

Evaluation on the Effect of Coal Mining on Soil Properties in Nalin Tao Hai Area in Yi Ji Huo Luo of Inner Mongolia

本文以伊金霍洛旗纳林陶亥镇煤矿集中区土壤性质为研究对象,通过野外调查取样和室内分析,对矿区土壤性质空间变化进行了研究,并运用主成分分析法对矿区土壤性质进行了综合评价。结果表明:内蒙古伊金霍洛旗煤矿开采对土壤性质影响显著。土壤性质随矿区影响半径的增加,采煤活动对其影响程度逐渐降低,且表层土壤受到的扰动最为强烈。相比矿区外部,矿区内部土壤受到影响较大,深层与表层土壤稳定性较差,而矿区外部土壤受到影响较小,土壤肥力流失随土层深度的增加而减缓。

The paper took soil properties of coal mining as the research object, which are in the YiJiHuoLuo county. The field sampling survey and laboratory analysis were used, the spatial variation of the soil properties was studied. In addition to, the soil properties were appraised comprehensively. The results showed that the coal mining has significant effects on soil properties in YiJiHuoLuo of Inner Mongolia. The comprehensive evaluation results of soil quality. The results showed, the influence of coal mining activities on soil properties was weaken with the enlargement of the action radius of coal mining area. At the same time, the top soil were strongly influenced by coal mining activities. Comparison with the outside of mining area, inside of mining area was suffering heavy influnces, the deep and surface soil showed low stability, the soil which is in the outside of mining area was influnced little and soil nutrient loss slow down tendency with the increase of the soil layer depth.
