摘要: 【目的】分析中国华北地区国家重点保护农业野生植物区系成分,为保护与持续利用资源提供参考。【方法】按照中国现代蕨类植物地理分布,种子植物分布区类型,D. Szymkiewicz属相似系数进行分析。【结果】华北地区国家重点保护农业野生植物有44种,隶属于24科39属。区系成分主要是温带性质,各类温带成分属占72.22%、热带成分属占13.89%、中国特有属占13.89%;各类温带成分种占54.76%、热带成分种占2.38%、中国特有种占42.86%,与相邻的东北区系关系密切,与西北区系相似程度较低。【结论】区内植物科有7个分布区类型、2变型,属有12个分布区类型、6变型,种有6个分布区类型和3变型。

Abstract: 【Objective】This article aims to analyze the elements of national key preserved agricultural wild plants in North China region, and to provide reference for protection and sustainable utilization of plant resources.【Method】On the basis of the geographical distribution of modern pteridophytes in China, the areal-types of seed plants and D. Szymkiewicz’s similarity coefficient in genera were analyzed. 【Result】 There are 44 species of national key preserved agricultural wild plants in North China, belonging to 39 genera and 24 families. They are mainly temperate in nature. At the generic level, various temperate genera, tropical genera and endemic genera to China contributed 72.22%, 13.89% and 13.89% of the total (excluding cosmopolitan genera). At the species level, various temperate elements, tropical elements and endemic to China contributed 54.76%, 2.38% and 42.86% of the total species. Compared with the flora of two neighboring areas, the flora is much more closely allied to northeast China than to northwest China.【Conclusion】There are 7 areal-types and 2 subtypes of families, 12 areal-types and 6 subtypes of genera and 6 areal-types and 3 subtypes of species in the geographical distribution.
