| 中文摘要 |
| 本研究采用网格和系统分层法,在全省范围内布没123个典型剖面,获得福建省61种元素土壤环境背景值。结果发现,福建省15种稀土元素土壤背景值高于全国土壤背景值。与全国若干元素土壤背景值比较,福建省亲硫元素、亲铁元素背景值较高。福建省土壤中硒、钼元素背景值分别为0.55、5.14mg/kg,相当于全国水平的2.5倍和4.3倍。文中还探讨了影响福建省土壤环境背景值的主要因素,提出福建省土壤资源合理开发利用建议。 |
| 英文摘要 |
| With the methods of network and systematic layers, 123 typical sampling sections were selected and soil environmental background values for 61 elements were determined in the whole region of Fujian province. The results show that the soil background values for 15 rare-earh elements in Fujian are higher than those in the country, that the background values for sulphophilic and siderophilic elements in Fujian are also higher compared with those of the same elements in the country and that the background value of Se in the soil of Fujian is 0.55mg/kg, 2.5 times as high as the level of the country. The major factors affecting soil environmental background values in the province are analyzed and suggestions for reasonable development of soil resource proposed. |
