摘要：在全面开展调查和资料整理的基础上,研究甘肃省甘南藏族自治州种子植物区系特征,并基于植物区系特征,探讨植物区系及与甘南州农林牧复合系统的结构特征、成因的联系。结果表明:甘南州种子植物共计108科577属2019种。在科级水平上,温带分布科32科,占全部科的29.63%;热带分布科31科,占全部科的28.70%;世界分布科45科,占全部科的41.67%。属级水平上,温带分布属440属,占全部属的76.26%;热带分布属73属,占全部属的12.65%;中国特有属15属,占全部属的2.60%。中国特有种共161种,其中热带分布型23种,占总数的14.29%;温带分布型111种,占特有种的68.94%。甘南州植物种类丰富,区系成分复杂,温带性质显著。植物生活型以草本为主,不同分布型物种数量随海拔变化呈先升高后下降的趋势。甘南州农林牧复合系统受到区系差异、海拔梯度、植物资源利用方式等因素的影响,形成一套以自然资源为基础、适应不同自然条件的生态产业体系。当地居民凭借对植物资源的了解及合理利用,促进农林牧复合系统的形成以及产业间的协调发展。
Based on a comprehensive investigation and data collection,we analysed the characteristics of seed plant flora in Gannan Tibetan Autonomous Prefecture,Gansu Province.We examined the relationship between plant flora and the structures and drivers of agroforestry-animal husbandry complex systems in the Gannan Prefecture are discussed.The results showed Gannan Prefecture harbours 2019 seed plant species belonging to 577 genera and 108 families.At the family level,32 families(29.63%)have a temperate distribution,31 families(28.70%)have tropical distribution,and 45 families(41.67%)have worldwide distribution.At the genus level,there were 440 genera(76.26%)have a temperate distribution,73 genera(12.65%)have a tropical distribution,and 15 genera(2.60%)have worldwide.Among the 161 species endemic to China,23(14.29%)are tropically distributed,and 111(68.94%)are of temperate distribution type.Gannan Prefecture is rich in plant species,complex in floristic composition,and strongly temperate in nature.Plant life forms were dominated by herbs,and the number of species with different distribution types first increased and then decreased with increasing altitude.Complex agroforestry and animal husbandry systems in Gannan Prefecture are influenced by flora differences,altitude gradients,and plant resource utilization methods,These factors together support the formation of ecological industry systems adapted to different natural conditions.Improved understanding and rational utilization of plant resources by local residents facilitated the development of agroforestry systems and the coordinated development of industries.
