Investigation and analysis of wild seed plant flora in Litang Gemu Nature Reserve
To comprehensively investigate the distribution of wild seed plant resources in the Gemu Nature Reserve in Litang County and provide scientific basis for the protection and rational utilization of regional wild plant resources,a comprehensive survey of wild seed plants in the reserve was conducted through survey methods such as setting up sample lines and plots,and the diversity and distribution characteristics of the wild seed plants flora in the reserve were comprehensively analyzed.The results showed that there were a total of 78 families,371 genera,and 1 021 species of wild seed plants distributed in the reserve.The dominant families mainly included Asteraceae,Gramineae,and Rosaceae,etc.The dominant genera were Rhododendron and Saxifraga.There were a total of 7 distribution types of wild seed plants in 78 families in the protected area,of which 25 families were distributed in the north temperate zone(32.05%),and 24 families were distributed in the world wide(30.77%)and pantropical zones(30.77%),respectively.The 371 genera consist of 15 geographical distribution types,of which 129 genera(34.77%)were distributed in the north temperate zone,47 genera(12.67%)were distributed in East Asia,and 13 genera(3.50%)were endemic to China.The horizontal distribution types of family and genus accounted for 46.67%and 100%of the domestic distribution types,respectively.There were 5 species of wild protected plants such as Cypripedium tibeticum.The wild seed plant species in Gemu Nature Reserve are abundant,with a complex floral composition and high conservation value.
