摘要： Studies on forest carbon sinks in the past years mainly focus on regional and national scale forest ecosystems, but ignore the relationships between topographical changes and forest carbon sinks within each component (vegetation, soil, litter) of forest ecosystem. Here we estimated the carbon storages and carbon densities in forest vegetation, soil and litter in Zu Mountains, Hebei Province, North China, using geographic information system (GIS) and the Geostatistical theory. We mapped the spatial distributions, analyzed and discussed the effects of vegetation types and topographical factors on forest carbon storage and carbon density. Results show that (1) Co-kriging (16.59% higher precision) and ordinary kriging interpolations are reliable at estimating forest carbon density, and Circular model was the Optimal one. (2) Total forest carbon storage is 83.92 x 10(4) t, with 13.25 x 10(4) tin vegetation, 69.71 x 10(4) tin soil, and 0.96 x 10(4) tin litter. Forest average carbon density is 144.34 t/ha, with 22.79 t/ha in vegetation, 119.90 t/ha in soil, and 1.65 t/ha in litter. (3) Spatial distribution maps of co-kriging interpolation show that the forest carbon density is similar to the DEM trend and significantly correlated with forest type, elevation and aspect. Our results suggest that co-kriging interpolation is suitable to estimate the forest carbon storage and carbon density. Forest carbon storage and carbon density in each component in Zu Mountains are both significantly different with forest type and topography. The natural forest protecting projects and scientific tending measurement are beneficial to carbon accumulation.
