| Abstract: | LI-8100 Automated Soil CO2 Flux System was used to study the spatial heterogeneity of soil respiration rate and its influence factors in a conifer-broadleaved forest in Dailing Forestry Bureau,Heilongjiang Province.Soil respiration rate,soil partitioning respiration rate,temperature and moisture at 10cm depth in 36 quadrats were determined under different intensities of selective cutting.Results show that the spatial heterogeneity of soil respiration rate at different quadrats is significant 6 years after s... |
| Keywords: | Conifer-broadleaved forests Selective cutting Soil respiration rate Spatial heterogeneity |
