UPGMA clustering map based on the plant species diversity in the desert area. The dendrogram and plant composition heat map were obtained based on UPGMA clustering of wild plant species composition in each sampling site. The plant species diversity situation and major human settlements were marked on the map (red dots represent plant biodiversity rich point; small blue dots represent plant biodiversity rare point; red plus symbols with a circle represent the major human settlements). UPGMA, unweighted pair‐group method with arithmetic.
