地下水中REE的含量和分布模式主要受岩石风化和成土作用影响。

REE contents and distribution patterns in groundwater are influenced by rock weathering and soil formation , more HREE than LREE inflow into groundwater so that difference in quantity between LREE and HREE in groundwater is not so great as that in soils .

陆地植物从土壤BSi库吸收的硅量远超过从岩石风化释放吸收的硅量，植物-土壤内循环的有效性强烈地影响着陆地生态系统中的硅向河流和海洋的输送。

Because the silicon absorbed by plants from soil BSi pool is far more than that released by weathering , plant-soil internal cycling can greatly affect the dissolved silicate fluxes from terrestrial ecosystem to rivers and oceans .

黑河水源于祁连山，山区岩石风化后，地表径流和地下径流携带大量可溶性盐类（主要是NaHCO3和Na2CO3）向黑河灌区汇集，使得该片土地盐分含量不断增加，土壤理化性质遭到破坏。

The rock of the area weathered , the surface river and subterranean river gathered in the Heihe River irrigated area with large amount of solubile saline ( mainly NaHCO_3 and Na_2CO_3 ), making the proportion of saline of this area increasing steadily , and the soiled destroyed greatly .
