Distribution (county) of every species in Fagaceae of China was searched by plant professional websites, published papers and books. Geographic Information System was used in the paper. Indices of spatial diversity patterns were gotten based on the county and Fagaceae of China. The patterns of every genus and type were studied quantitatively. Results showed that: (1) in Fagaceae of China, patch richness, diversity indices, number of all patches and total shape index in Cyclobalanopsis, Quercus, Castanopsis and Lithocarpus are significantly higher than those in Formanodendron, Castanea and Fagus. There is a patch in Formanodendron, so spatial diversity patterns in genera and species are the same. Formanodendron is different from other genera in spatial diversity patterns. (2) In Fagaceae of China, there are positive correlations between indices of spatial diversity patterns in other genera. These indices are patch richness, diversity indices, number of all patches and total shape index. The correlations between total area and number of all patches, diversity indices or total shape index are positive, but the correlation between total largest patch index and evenness index is negative. (3) All indices, such as area of patch type, percentage of the genus, number of patches, largest patch index and shape index, decrease as value of patch type increases in every genus except for Formanodendron. The correlation between patch type and every index is negative. All correlations are significant. (4) Patch types including 1-7 species cover main distribution range of the genus because total area or number of patch of these types are more than 80% that of the genus in Cyclobalanopsis, Quercus, Castanopsis or Lithocarpus of Fagaceae in China. The value of every index in patch types which number of species is more than 7, is lower because the distribution range of every type is narrower, but its diversity is higher.
