Description :
With a total of 886 data sets distributed in different regions of China, the relation of soil organic matter (SOM) concentration to climate and altitude was investigated. According to climate gradient and vegetation community succession, 6 geographical regions were divided to identify the key factors regulating surface SOM concentration in different geographical regions. Correlation analyses indicates that surface SOM concentration is in general negatively correlated with annual mean temperature (T), and positively correlated with annual mean precipitation (P) and altitude (H). Surface SOM concentration in southwestern China is determined by a linear combination of T, P and H.
