- 摘要:
- 为开展重要物种的科普宣传、保护和监管，并促进后续各项管理条例及政策的制定，以新疆塔里木胡杨国家级自然保护区为调查范围，通过实地调查、结合文献资料数据分析了区域自然地理概况、维管植物种类与组成、珍稀濒危及重点保护植物种类与保护等级、资源植物的类型及利用方向。结果表明，保护区野生维管束植物有37科96属147种，蕨类植物1科1属1种，裸子植物1科1属1种，其他均为被子植物。从科级大小的统计结果来看，单种科有17科，占总数的45.94%，寡种科（2~10 种）有14科，占总科数的37.84%，10种以上的科仅6科，占总数的16.22%。野生种子植物95属可划分为10个分布型和8个变型。植物区系中占比最多的是世界分布，其次是北温带分布、地中海、西亚至中亚分布和旧世界温带分布作为植物区系的主体分布型，体现了保护区植物区系干旱、温带基本属性，多种分布区类型的出现也体现了保护区植物区系多元交流的特点。区内珍稀濒危植物共3种，可利用的各类资源植物达到30科71属104种，占到本地区维管束植物种类总数的70.75%。
- Abstract:
- In order to promote the popularization, protection, and regulation of important species, as well as to facilitate the formulation of subsequent management regulations and policies, this study focused on the Xinjiang Tarim Populus euphratica National Nature Reserve, conducting field surveys and integrating literature data to analyze the regional natural geography, species composition of vascular plants, rare and endangered plant species with their conservation status, and the types and utilization directions of resource plants.The results indicated that the reserve had 147 species of wild vascular plants, belonging to 96 genera and 37 families. Among these, there was 1 species of fern (1 family, 1 genus), 1 species of gymnosperm (1 family, 1 genus), and the remainder were angiosperms. At the family level, 17 families (45.94%) were monotypic, 14 families (37.84%) were oligotypic (2~10 species), and only 6 families (16.22%) contain more than 10 species. The 95 genera of wild seed plants can be classified into 10 area-types and 8 variants. The flora was predominantly characterized by Cosmopolitan Type, followed by North Temperate Distributions, Mediterranean, West Asia to Central Asia distribution, and Old World Temperate Distribution, reflecting the arid and temperate nature of the reserve’s flora. The presence of multiple distribution types also highlights the region’s diverse floristic exchanges. The reserve hosts 3 rare and endangered plant species, and 104 species of resource plants from 30 families and 71 genera, accounting for 70.75% of the total vascular plant species in the area.
