【摘要】 目的：摸清横山国家森林公园植物资源现状，为其监测保护和开发利用提供科学依据。方法：通过文献分析、现场考察、样方法调查等，对横山国家森林公园内的植物资源多样性、群落结构、植被类型、分布区系、特有植物和珍稀植物等进行调查分析。结果：横山国家森林公园有植物106科208属246种，可分为3个植被型组、6个植被型、6个植被亚型、13个群系。植物区系从科的类型看，呈热带区系向温带区系过渡的特征，世界分布和温带的植物区系更具优势；从属的区系类型看，包含了18种不同区系，热带至温带区系过渡性质明显；中国特有植物1科9属，国家重点保护植物6种。结论：安徽横山国家森林公园的植物资源及植被类型丰富；地理条件复杂，区系起源古老，具有亚热带植物区系特征和南北交融的特点；特有现象明显，珍稀植物丰富，有较大的野生植物资源保护及可持续发展价值。更多还原

【Abstract】 Objective: To understand the current status of plant resources in Hengshan National Forest Park, and provide scientific basis for its monitoring, protection, development and utilization.Methods: The plant resources, community structures, vegetation types, distributional floras, endemic, and rare plant species within Hengshan National Forest Park were surveyed and analyzed, utilizing a combination of literature review, field investigations, and sampling methodologies.Results: A total of 246 plant species, belonging to 208 genera and 106 families, were identified in Hengshan National Forest Park. The vegetation was categorized into 3 types, 6 subtypes, 6 formations, and 13 distinct groups. The flora exhibited a tropical-to-temperate transitional characteristic, dominated by worldwide and temperate species. It encompassed 18 distinct floristic categories, highlighting the tropical-to-temperate transition. Additionally, 9 endemic genera and 1 family, along with 6 nationally protected plant species, were recorded. Conclusion: Hengshan National Forest Park in Anhui Province was revealed to be abundant in plant resources and diverse in vegetation types. Characterized by complex geographical conditions and an ancient subtropical flora, it exhibited a unique blend of northern and southern flora, marked endemism, and a rich variety of rare plants. These attributes underscored its significant value for the conservation and sustainable development of wild plant resources.更多还原
