其他摘要 | This study selected the forest soils from 8regions under different longitudes in the Loess Plateau as
research objects , and explored the soil nutrients , soil microbial biomass and their ecological stoichiometry
under different longitudes.The results showed that the contents of soil carbon , nitrogen and microbial bio -
mass carbon , nitrogen and phosphorus overall gave a trend of decreasing first and then increasing with the
change of longitudes.There was a coupling relationship between soil microbial biomass carbon , nitrogen and
phosphorus and soil carbon and nitrogen , and the response to environmental factors was consistent.The spa -
tial distribution of soil phosphorus content was stable.The soil carbon - nitrogen ratio was around 8 , and the
spatial distribution of soil organic carbon and total nitrogen was consistent.The soil microbial biomass car -
bon - nitrogen ratio was about 9 , and the microbial biomass nitrogen - phosphorus ratio was about 5 , which re -
flected that the soil microbial biomass carbon - nitrogen and nitrogen - phosphorus ratio were relatively stable ,
but the soil microbial biomass carbon - phosphorus ratio showed a trend of increasing first and then decreasing.
Soil microbial biomass carbon , nitrogen and phosphorus had a strong correlation with soil moisture.Soil nu -
trients and soil microbial biomass carbon , nitrogen and phosphorus and their ecological stoichiometry were
the result of the comprehensive action of environmental factors. |
