鸡东县土壤锗元素富集特征调查与分析

Investigation and analysis of germanium enrichment characteristics of soils in Jidong County

本文划定鸡西市鸡东县为调查区,根据调查区水文、地形地貌、土壤类型特征等制定详细调查方案,对鸡东县土壤锗元素地球化学背景值、富集程度等特征进行对比分析,结果表明,调查区内富锗土地面积约76.92 km2(Ge≥1.5 mg/kg),占调查区面积的3.53%,足锗土地面积约638.27 km2(1.5 mg/kg>Ge≥1.4 mg/kg),占调查区面积的29.28%,并呈现中部台地、丘陵及低山一带富集较高,南北部低山区富集较少的分布特征。

In this paper,Jidong County,Jixi City was designated as the investigation area,and a detailed investigation plan was formulated according to the hydrology,topography and geomorphology of the investigation area and the characteristics of soil germanium element geochemical background values and enrichment degree in Jidong County were compared and analyzed,and the results showed that the area of germanium-rich land in the investigation area was about 76.92 km2(Ge≥1.5 mg/kg),accounting for 3.53%of the investigation area,and the area of sufficient germanium.The area of germanium-rich land is about 638.27 km2(1.5 mg/kg>Ge≥1.4 mg/kg),accounting for 29.28%of the survey area,and shows the distribution characteristics of higher enrichment in the central terraces,hills and low mountains,and less enrichment in the low mountains in the north and south.
