安太堡露天煤矿复垦地土壤养分相关研究

以平塑安太堡露天煤矿为例，研究了矿区排土场矸石风化物和黄土二种主要母质发育的土壤有机质、全氮、速效磷、速效钾状况及其相关性。结果表明，矸石和黄土母质对有机质、全氮的影响显著，对速效磷、速效钾的影响未达到显著水平；黄土母质发育的土壤有机质和全氮含量呈显著正相关，而矸石风化物有机质和速效钾含量呈显著负相关，有机质和其它的养分指标相关性不显著。

CORRELATION BETWEEN NUTRIENTS OF RECLAIMED SOIL IN ANTAIBAO OENCAST MINE

In the case of An Taibao Opencast coal mine in Pingshuo, this paper discusses organic matter, total N, rapidly available P, rapidly available K and their correlation in soil developed from gangue and loess parent material on dumping site. The results show that the effect of gangue and loess parent material on organic matter and total N is significant. but its effect on rapidly available P and K is not significant; there are evident correlation between organic matter and total N of soil developed from loess parent mateial, and evident ant - correlation between organic matter and rapidly available K of material weathered from gangue , but organic matter and other nutrient indexes are less evident correlated.
