Title: Spatial Heterogeneity of Soil Humus Under Different Management Type of Pinus koraiensis Forests
Abstract: Through the manner of field investigation and room experiments,by using software of SPSS 13.0 and ArcGis 9.3,geostatistical analysis tool,the spatial heterogeneity of the soil humus under virgin Pinus koraiensis forest,Betula platyphylla and Pinus koraiensis mixed forestⅠ(Pinus koraiensis natural regeneration),Betula platyphylla and Pinus koraiensis mixed forestⅡ(Pinus koraiensis planted) and pure Pinus koraiensis plantation were studied.The soil humus content under different forest was different,the soil humus content under Betula platyphylla and Pinus koraiensis mixed forest was higher than that under pure Pinus koraiensis plantation.The characteristics of the spatial heterogeneity of the soil humus under different forest types were different,the spatial heterogeneity of the soil humus under four forest types were influenced by random factors,but the auto relationship part of the soil humus spatial heterogeneity and the scale of the soil humus spatial heterogeneity under Betula platyphylla and Pinus koraiensis mixed forests were bigger than that under pure Pinus koraiensis plantation.The spatial distribution pattern of the soil humus under Betula platyphylla and Pinus koraiensis mixed forests was superior to that under pure Pinus koraiensis plantation.The results would provide a theory basis for the recovery and the sustainable management of the Pinus koraiensis forest.
