Additional file 1 of Spatial pattern and driving factors of biomass carbon density for natural and planted coniferous forests in mountainous terrain, eastern Loess Plateau of China

Abstract

Additional file 1: Annex 1. More information on multi-group SEM. Annex 2. The priori (a) and good-fitting (b) structure equation models showing the factors that have direct and indirect effects on biomass carbon density of coniferous forests in Shanxi, China. Annex 3 The priori (a) and good-fitting (b) structure equation models showing the factors that have direct and indirect effects on biomass carbon density of coniferous forests in Shanxi, China. Annex 4 Biomass carbon storage (BCS) of individual age groups of natural, planted and all coniferous forests in the study region. Annex 5 Direct, indirect and total effects of stand age (AGE), stand coverage (COV), elevation (ELE), latitude (LAT) and annual mean precipitation (PRCP) on biomass carbon density (BCD) for natural and planted coniferous forests and for all coniferous forests. Annex 6 Multi-group comparison of path coefficients between forest types. A non-significant value, highlighted in bold, indicates that the path contribution to the model is equal between forest types. Annex 7 Direct, indirect and total effects of stand age (AGE), stand coverage (COV), latitude (LAT), annual mean temperature (TEMP) and annual mean precipitation (PRCP) on biomass carbon density (BCD) for natural and planted coniferous forests and for all coniferous forests
