中文摘要	【目的】为研究干旱区露天煤矿开采活动产生的煤粉尘对周边地区土壤理化性质及土壤可蚀性的影响。【方法】选取具有代表性的新疆准东煤田红沙泉煤矿为研究区 ,在排土场、堆煤场、矿区2000 m以内采集土壤样品,分析土壤理化性质并计算可蚀性因子(EF)值,探讨土壤理化性质与(EF)值的关系并分析两者的空间分布规律。【结果】①煤粉尘沉降对土壤各项理化性质产生不同程度的影响,其中有机质影响最显著,随距离呈现由高到低的指数分布。排土场表层土壤颗粒结构与其他采样点有显著差异,土壤表层砂粒含量明显减少,土壤黏粒含量明显增加。②土壤EF值与土壤pH值、土壤全磷、土壤砂粒含量均呈极显著(P <0.01)的正相关关系,与土壤有机质、土壤黏粒、粉粒含量呈极显著(P <0.01)的负相关关系。相关性大小排序依次为pH >黏粒>有机质>砂粒>粉粒>全磷>碳酸钙>全盐>容重>全氮。③采煤活动形成的堆煤场和排土场对土壤可蚀性起到降低作用。土壤EF值在堆煤场处达到最低值,煤矿区土壤EF值也明显小于周边地区。【结论】采煤活动对矿区周边土壤理化性质具有显著影响,进而降低土壤可蚀性。
英文摘要	【Objective】The present paper aimed to study the influence of coal dust generated by open-pit coal mining activities in the arid area on the soil physical and chemical properties and soil erodibility in the surrounding areas.【Method】A representative Xinjiang Zhundong coalfield Hongshaquan coal mine was selected as the study area,in the dumping site and coal soil samples were collected within 2000 meters from the field and the mining area.The physical and chemical properties of the soil were analyzed and the erodibility factor(EF)values were calculated.The relationship between soil physical and chemical properties and(EF)values was discussed and the spatial distribution of the two was analyzed.【Result】(i)Coal dust deposition had different effects on the physical and chemical properties of the soil,among which the organic matter had the most significant effect,and the exponential distribution from high to low with distance.The grain structure of the surface soil of the dumping site was significantly different from other sampling points.The sand content of the soil surface was significantly reduced,and the soil clay content was significantly increased.(ii)Soil EF and soil pH,soil total phosphorus and soil sand content were positively correlated(P <0.01),and soil clay and powder content were extremely significant negative correlation(P <0.01).The order of correlation was as follows:pH >clay >organic matter >sand >powder >total phosphorus >calcium carbonate >full salt >total weight >total nitrogen.(iii)The coal yard and dumping site formed by coal mining activities had a reducing effect on soil erodibility.The soil EF reached the lowest value at the coal yard,and the soil EF value in the coal mine area was also significantly smaller than that in surrounding area.【Conclusion】Coal mining activities have a significant impact on the physical and chemical properties of the soil around the mining area,thereby reducing soil erodibility.
