| 摘要: |
| 应用地统计学和地理信息系统（GIS），对广东省东莞市森林土壤有机质（0～1 m）的空间变异性和主要林分土壤有机质含量进行分析，结果表明：东莞市森林土壤有机质属中等变异性；具有中等的空间相关性；空间分布呈东西高、中北低的趋势；主要林分土壤有机质含量由小至大依次为：荔枝林、桉树林、马尾松林、针阔叶混交林、马占相思林、阔叶混交林。 |

| 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. |
