Abstract：ToclarifythecurrentdistributionofwildteaplantsinYoujiangDistrict，BaiseCity，thisstudyutilizedsatellite imagery combined with geographic information technology，andconducted field transectsurveys.Using the software suchas OviMapand Xinzhi SateliteMap，thedistributionof wildtea plantcommunities was studied.Theresults indicate that wild tea plants in Youjiang District are primarily distributed in the geographic range of 106∘13′36′′ 1 ⋅106∘23′53′′ （20 longitude and 23∘38′10"-23∘45′39" latitude，at altitudes of 1 191～1 456m ，with a total distribution area of approximately2596.88 hectares.The population is estimatedat 629，500 individuals，withadensityof approximately242.41 plants per hectare.The plants are concentrated in valleys and mountainous areas of Baping Village，Daling Village， Pingman Vilage （Daling Township），Longhong Vilage （Longhe Township）and Guqi Village （Panshui Township）. A sample survey of 281 wild tea plants reveals that all were arbor-type， with treheights ranging from 300 to 2000cm canopy spreads of 100～1 300 cm， and basal circumferences of 40～230cm . The leaves were predominantly oblong， with 7～13 pairs of veins， leaf lengths of 10.00～24.50cm ，and leaf widths of 4.00～10.00cm . The Youjiang District boasts an abundance of wildtea resources distributed in aconcentrated and contiguous manner.These resources exhibit distinctivecharacteristics includinganarrowaltitudinalrange，astrongdependenceonmicro-terrainfeatures，andspecific community symbiosis.Thecommunitiesdemonstrate remarkable ecological adaptabilityand genetic diversity.However， wild tea plants face multiple threats suchas indiscriminate harvesting，improper conservation measures，and forestland reclamation， necessitating urgent protection and rational utilization.
