摘要
The present study attempted to evaluate the influence of human activity on major elements(Na_2O,MgO, Al_2O_3, SiO_2, K_2O, CaO, Fe_2O_3), and to find a method to explore correlations between major elements and human disturbances, according to geospatial theories and methods. The study results indicate that landscapes influence major elements in diverse ways: Al_2O_3 is closely related to road and mine landscapes; strong relationships exist between MgO, Fe_2O_3, CaO, and SiO_2 and roads;Na_2O, SiO_2, and Fe_2O_3 are unrelated to city landscapes;and Na_2O is unrelated to road and mine landscapes.
The present study attempted to evaluate the influence of human activity on major elements （Na2O, MgO, A1203, SiO2, K2O, CaO, Fe203）, and to find a method to explore correlations between major elements and human disturbances, according to geospatial theories and methods. The study results indicate that landscapes influence major elements in diverse ways： Al2O3 is closely related to road and mine landscapes; strong relationships exist between MgO, Fe2O3, CaO, and SiO2 and roads; Na2O, SiO2, and Fe2O3 are unrelated to city landscapes; and Na2O is unrelated to road and mine landscapes.
