Taking the wild vine resources on the main island of Pingtan and surrounding islands as the research object,the sampling method was used to conduct field investigation and collection,and the TOPSIS method was used to comprehensively evaluate and analyze the development and utilization of vine resources in the study area.The results showed that there were 37 species of vines in Pingtan,belonging to 18 families and 32 genera.There were many single families.Leguminosae and Vitis were the dominant families.Wild vines were mainly composed of genera with only one species,accounting for the total 87.50% of the genera;dicotyledonous wild vines accounted for 94.59%,with obvious advantages.Monocotyledonous vines and fern vines were relatively poor in species;climbing methods were mainly winding,accounting for 75.68%,tendrils,adsorbents,barbs and other trailing species accounted for less.Thirty species of vines with excellent comprehensive evaluation results were selected,such as Parthenocissus semicordata,Parthenocissus tricuspidata,Vitis bryoniifolia,Cayratia japonica,Smilax china,Calystegia solderanella,Canada rosea,etc.,which can be applied to three-dimensional gardening.In addition,based on the actual situation in Pingtan,the application methods of corresponding vines in gardens and the development and protection suggestions were put forward.
