| Abstract: | Geostatistics and GIS were applied to analyze spatial variability of forest soil organic matter and soil organic matter content of main forest stands in Dongguan. The results showed that both variability and spatial correlation of forest soil organic matter in Dongguan were moderate; the spatial distribution of forest soil organic matter was high in the east and west districts and low in the middle and north districts; sequence of soil organic matter contents of main forest stands was as follows: Litchi chinesis forest, Eucalyptus forest, Pinus massoniana forest, conifer and broadleaved mixed forest, Acacia mangium forest and broadleaved mixed forest. |
