The Diversity Composition and Distribution Characteristics of Resource Plants in Xinjiang
[Objective]Identifying the species composition and spatial distribution of Xinjiang's resource plants is crucial for their effective conservation.[Method]Based on an extensive review,collection,and organization of literature,focuses on the vascular plants naturally distributed in Xinjiang,we gathered,organized and summarized information on the types,distribution,and habitats of Xinjiang's resource plants and analyzed the basic composition,geographical and habitat distribution characteristics of Xinjiang's resource plants.[Result]1)There are a total of 1003 species of resource plants naturally distributed in Xinjiang,belonging to 104 families and 460 genera.Among the three groups of ferns,gymnospermae and angiosperm,angiosperm plant species are relatively abundant,accounting for 96.31%of the total species.Based on the type of use,these resource pants can be categorized into edible,medicinal,industrial,and protective plants,with medicinal plants making up the majority at 77.77%.The life forms include herbs,shrubs and trees,with herbs being the predominant form accounting for 82.35%.2)The horizontal geographical distribution across cities is uneven,mainly concentrated in several prefecture-level cities in northern Xinjiang,with the Altay region having the richest species composition,containing 70.09%of the species.3)The vertical geographical distribution across altitudes is broad,mainly concentrated in the mid-altitude range of 1000～2100 m,showing a unimodal distribution pattern that first increases and then decreases with rising altitude.4)The distribution across habitats is uneven.Grassland and forest,are types of(natural)vegetation containing the most species,accounting for 32.70%and 31.80%of the total species,respectively.[Conclusion]Xinjiang's resource plants have a rich composition,with herbs being the main body and medicinal plants being the most numerous.The spatial distribution of Xinjiang's resource plants is uneven,mainly concentrated in the mid-altitude regions of the mountains in northern Xinjiang,primarily in grassland and forest habitats.This study provides a reference for the conservation of resource plants diversity in Xinjiang region.
