The flora of seed plants in Gannan Prefecture and the causes of agroforestry and animal husbandry complex system
摘要
Abstract
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 2 019 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.关键词
