| 中文摘要: |
| 通过岩-土剖面地球化学元素测试，分析了云贵山优质茶叶产地岩-土系统元素的迁移分配规律。研究结果表明，岩石中N、P、Mn、Zn、Mo、B元素含量高于中国主要地球化学标准物质的标准值，表土层中N、P、B、Mn、Zn、Mo、Al2O3、K2O、Fe2O元素和氧化物含量高出中国土壤背景值。岩石和表土层元素中N、P、S、B表现明显富集，元素迁移系数在073126之间，显示了具有相似化学行为的元素具有相似的迁移规律。土壤层中元素含量与茶叶中元素含量呈正相关，岩-土系统元素对优质茶叶生长及品质有着重大影响。在相似环境下，寒武系碎屑岩分布区有利于茶树生长和品质的提高。 |

| By geochemical element test of rock-soil section, the element migrate and distribute regulation in rock-soil system in Yunguishan are analyzed. The results shows N, P, Mn, Zn, Mo, Al2O3, K2O, Fe2O and oxide in the surface soil are higher than the soil background value of China, N, P, S, B in the rock and soil shows obvious concentration, the element migration value is 0.73 to 1.26, it show the elements with chemical activity have the same migrate regulation. The element in the soil has positive relation with the element in the tea. The element in the rock-soil system is very important for the growth and quality of tea. In the similar environment, Cambrian clastic rocks distribution areas were favorable to the tea trees growing and tea quality enhanced. |
