Abstract:Spatial variations of soil characteristics in forest directly always determine the forest productivity and the approach to ecological restoration. However, in plantation forests that have been suffered from many disturbances due to human activities, spatial distribution of soil physical and chemical properties are still unclear. To examine the status of soil properties in different plantation forests, altitude and soil depth in southern mountainous area in Anhui Province, we sampled soil from six forests in Meichen forestry station at Dongzhi County in October 2016, and measured its pH, Ec, TOC, LOC, DOC and TN at the soil depth of 0-20 cm and 20-40 cm. The results were as follows: 1) The soil chemical characteristics of artificial forest in Meicheng forestry station were mainly affected by forest types, and the order of soil fertility was generally ranked as coniferous forest > hard broad-leaved forest > broad-leaved mixed forest; 2) The dominant species in forest rather than plant community diversity drive the influences of forests on soil chemical properties; 3) Altitude also has significant impact on the chemical properties of forest soil; 4) The influence of plantation types on soil properties would strengthen the increasing of profile depth, while the effect of altitude would not. Taken together, regulation of forest types are the effective approach to improving the soil nutrient status of the Mecheng artificial forestry station, and planting coniferous forests can promote soil nutrients and carbon sequestration capacity at surface profile, as well as optimize the composition of SOC at sub-surface profile.
