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
(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.

Stone forests are unique karst surface landforms. The Lunan stone forests developed from underground karren. Where this type of surface is highly developed in China, it is defined as a shilin. Diverse examples of stone forests that formed in almost
forms, composed rock forms, and forms shaped by rain water. Because of the exceptional characteristics of this karst phenomenon in China, we propose that the term shilin be used for this type of stone forest in the profesional literature. - (IKR)
