Abstract:Map of spatial distribution of genera was made by the county and Hamamelidaceae of China in ArcGIS software, number of every patch, area and perimeter were gotten from the maps. Shape indices, largest patch indices, Simpsons evenness indices and Shannons evenness indices were calculated. The characteristics of geographical distributions of each genus in Hamamelidaceae of China can be quantitatively analyzed. It provided the basis for the protection, development and utilization of Hamamelidaceae resource. Results showed that: (1) Chunia, Parrotia, Tetrathyrium, Fortunearia, Hamamelis and Mytilaria are monotypic genera. The total area of the first three genera is small and the distribution is narrow, while the total area and distribution range of the last three genera are larger than the first three genera; Disanthus, Sinowilsonia, Rhodoleia, Eustigma, Semiliquidambar, Exbucklandia, Altingia, Sycopsis, Distylium, Loropetalum, Corylopsis and Liquidambar are multiple genera. When area of genus increases, distribution range of genus basically increases. And the multiple genera are twice as many as the monotypic genera. (2) Total area and largest patch area of Liquidambar are the largest, which can reflect spatial distribution and characteristics of Hamamelidaceae in China. (3) Spatial distribution of all genera in Hamamelidaceae of China is disjunction. Chunia, Distylium, Loropetalum and Liquidambar have the main distribution area. Fortunearia, Hamamelis, Mytilaria, Sinowilsonia, Semiliquidambar, Exbucklandia, Altingia, Sycopsis and Corylopsis have main and secondary area. Parrotia, Tetrathyrium, Disanthus, Rhodoleia and Eustigma are all scattered area.
