Using ArcGIS and Geostatistics to Study Spatial Pattern of Forest Litter Carbon Density in Zhejiang Province, China
A total of 840 forest litter samples were collected based on a 4 km (south-north) ×6 km (east-west) grid system in Zhejiang Province.Traditional statistics and geostatistics were applied to study the spatial pattern of forest litter carbon density in an ArcGIS environment.Forest litter carbon density values were very variable,ranging from 10.2 kg hm-2 to 4,289.8 kg ha-2,with an average of 1,627.1 kg hm-2.Spherical model was chosen to fit the experimental semi-variogram.The high nugget/sill (0.6275) value revealed that random variation played a key role in spatial heterogeneity of forest litter carbon density; human activities and land management further weaken its spatial correlation.Forest litter carbon density in Zhejiang province was above the average level of forest in China.High forest litter carbon values were mainly distributed in hilly region in Zhejiang,while HangJiaHu Plain,NingShao Plain and coastal areas had low forest litter carbon density due to low forest coverage.
