Abstract

Abstract:

To elucidate the vertical distribution of soil organic carbon （C）， nitrogen （N） and phosphorus （P） concentration in Qilian Mountain northern foot，the eco-stoichiometric characteristics at different elevations and their influencing factors were discussed. The results showed that the soil SOC， N and P content decreased with the increase of soil depth， and the significant aggregation was observed at topsoil； In the 0-40 cm soil layer， the average contents of soil SOC， N and P showed a trend of rising first and then declining with the increase of altitude， and reached the highest at the middle and high altitude area. Notably， the variation of P content is small and relatively stable. The C/N was higher at attitude of 3 128-2 814 m， and especially， the highest at 3 075 m. However， soil C/P and N/P showed a downward trend with the increase of altitude， and they were all the highest at the middle and high altitude area， while soil N/P showed the highest level at 3 454 m and the lowest level at 2 814 m. Meanwhile， there was no significant difference in soil C/N and N/P among different land types but significant difference in C/P. The effects of the three vegetation types on soil C/N and C/P were： arbor forest > alpine shrub > alpine grassland， while N/P was： alpine shrub > arbor forest > alpine grassland. Vegetation type and altitude are the main factors affecting the eco-stoichiometric ratio of soil C， N and P， followed by coverage and slope aspect.

Key words: Qilian Mountains, altitude, soil, stoichiometry ratio
