| Abstract: | Through analyzing the features of landscape geochemistry in Gansu, this paper divided Gansu into 6 geochemical landscapes.According to the scale 1∶200000 stream sediment survey data by the Bureau of Geology and Mineral Resources of Gansu Province, the paper computed the arithmetic means and standard deviations of 39 elements′ values of every landscape by statistics,and contrasted them with the regional backgrounds of stream sediments in China. |

| Keywords: | Gansu landscape geochemistry division element value feature contrast |
