摘要:

蔷薇科(Rosaceae)是在中国广泛分布并具有重要经济价值的植物类群, 但蔷薇科资源植物的物种多样性格局及其保护状况尚缺乏较系统的评估。该文旨在: 1)整理中国蔷薇科资源植物名录, 显示其物种多样性格局及热点地区, 并探究这一格局的形成机制。2)评估中国蔷薇科资源植物的保护状况, 为其保护规划提供基础数据。通过广泛收集整理《中国植物志》、省级植物志等资料中关于蔷薇科的记录, 建立了中国蔷薇科物种名录(共914种), 确定了物种的主要经济用途(包括食用植物、园林绿化植物、药用植物和水果种质资源), 并建立了每种植物的高精度分布图。在此基础上, 估算了蔷薇科全部物种及主要资源植物类别的物种多样性格局, 并利用广义线性模型和冗余分析探讨了蔷薇科物种多样性格局与环境的关系。最后将物种分布与中国国家级和省级自然保护区进行叠加分析, 评估了蔷薇科植物的保护现状。结果显示: 1)四川盆地北部、东部和西部山区以及横断山区是中国蔷薇科植物的热点地区。2)蔷薇科植物多样性主要受水分因子影响。3)横断山区、云南东南部和西藏东南部等地是保护薄弱物种集中的区域, 而悬钩子属(Rubus)等类群的保护不足。

Abstract:
Aims Rosaceae is a widely-distributed family with numerous economic resource plants in China. However, the species richness pattern and the current conservation status of resource plants remain poorly evaluated. Here we aim to identify the economic resource plants of Rosaceae in China, estimate the species richness patterns for all Rosaceae plants combined and for different resource groups and evaluate the relationships between species richness patterns and environmental variables. We also evaluate the current conservation status of economic resource plants of Rosaceae.
Methods We first made the species list of all 914 Rosaceae species in China and identified the species with different economic usages, including edible, ornamental, medicinal plants and fruit germplasm resources. We then collected high-resolution distribution maps of all Rosaceae species, estimated the species richness patterns by overlapping these maps, and identified the diversity hotspots of different species groups. With high-resolution environmental data, we compared the effects of different environmental variables on the species richness and species composition of all Rosaceae species combined and the four main resource groups using generalized linear models (GLM) and redundancy analysis (RDA). Finally, we evaluated the conservation status of Rosaceae with distribution data overlaid by maps of nature reserves of China in ArcGIS.
Important findings 1) The species richness hotspots of Rosaceae in China are mainly located in the mountain areas in the north, east and west of Sichuan basin as well as Hengduan Mountains. 2) Species richness patterns of Rosaceae are mainly determined by humidity factors. 3) Poorly protected species are mainly in Hengduan Mountains, Southeast Yunnan and Xizang, and concentrated in the genus of Rubus.
