Decomposition processes of Tilia amurensis leaves in the Changbai Mountain forest ecosystem

Abstract

Abstract: A 4-year field experiment was carried out in the Changbai Mountain to study the decomposition process of Tilia amurensis leaf and its affecting environmental factors.The results reveal that the decomposition process of Tilia amurensis leaves could be expressed by an exponent equitation.With the increase of elevation and the change of vegetation types,the decomposition rate in 1～5 standard experimental fields was -0 391,-0 339,-0 257,-0 198 and -0 125,respectively,indicating that the decomposition rate was decreased with ascending elevation.The maximum decomposition took place when the environment was in the shadow of 60%～80%.The leaves were acceleratively decomposed when the tested moisture was increased.Moisture affected the decomposition process more strongly than light.
