摘    要:采用地理信息系统技术,制作空间分布图、从空间上计算多样性格局指数,研究中国壳斗科植物属、种的空间多样性分布格局。结果显示,云南南部、广西北部和广东北部的属、种数量均较多,是中国壳斗科植物多样性的重要分布地区,甘肃南部、陕西南部、河南西部及南部是壳斗科植物向南、向北扩散的重要通道;从多样性指数来看,种的多样性指数值均比属的值高,但均匀度指数却是属的值高;当属或种的数量为1时,其所占面积、占景观的比例、斑块数量、最大斑块指数、景观形状指数均最大,随着属或种的数量逐渐增加,其多样性明显提高,但其各项指标基本呈依次降低的趋势。通过对壳斗科植物空间多样性格局进行量化研究,获取了中国壳斗科植物空间多样性分布规律及多样性格局数量特点,利用地理信息系统技术可以使多样性研究体现出空间性和定量化的特征。

关 键 词:壳斗科  空间多样性  空间多样性格局  地理信息系统  中国

Abstract:The spatial distribution patterns of species and genera of Fagaceae in China were studied by geographic information system (GIS) technology, with the spatial distribution maps and indices of diversity patterns calcaulated. Results showed that south of Yunnan, north of Guangxi, and north of Guangdong were important ranges of Fagaceae diversity in China based on the greater number of genera and species. South of Gansu, south of Shaanxi, and west and south of Henan, which connected southern and northern China, were important areas of Fagaceae dispersal. Diversity indices of species were higher than those of genera, but the opposite was found for the evenness indices. When the number of genera or species was 1, the total area, percentage of landscape, number of patches, largest patch index, and landscape shape index were maximum. When the number of genera or species increased, those indices gradually decreased with number. Based on quantitative study, the spatial distribution and diversity patterns of Fagaceae in China were obtained. The use of geographic information system technology clarified the distinctiveness of the spatial and quantitative distribution.
Keywords:Fagaceae  Spatial diversity  Spatial diversity pattern  Geographic information system  China
