明长陵土壤地球化学特征

摘要

对明长陵陵墓和外围土壤特征开展地球化学研究，发现长陵陵墓土壤Cl、S、P、N、C、Hg、Au和有机质含量在表层显著富集，陵墓内土壤各元素含量高于外围土壤。陵墓内五供两侧土壤Hg和Au元素含量出现异常，影响皇陵外东南向土壤Hg，以及南向和西南向土壤Au含量。陵墓土壤稀土总含量略有差异，但土壤稀土元素分布模式相似，表明陵墓内土壤为同源物质。%In this paper the geochemical characteristics can be used to study soil inside and outside of Changling Tomb. The study results show such elements as Cl, S, P, N, C, Hg, Au and organic matter in the Tomb soil also enrich in surface. But Hg and Au are anomaly on both sides of Wugong, which affects soil Hg in the southeast of the Tomb outside and soil Au in the southwest and south of the Tomb outside. The results show that difference of the total REE content in soils between inside and outside Tomb is not obvious, and the REE distribution patterns are similar to each other, which suggests that the soils are originated from the same source area.
