Abstract: The application prospect of different wild ornamental plants varies greatly. Comprehensive evaluation can provide clear goals and prominent keys on the landscape exploitation and application avoiding unordered and random selection. A synthetical assessment was established to evaluate the potential on landscape exploitation and application of 80 wild trees and shrubs in Mount Yuntai of Lianyungang based on the analytical hierarchy process （AHP），which included adaptability，ornamental value，and exploitation value as criterion layers and 13 evaluation factors，especially concerning ecological functions and beautification benefits. Sequence was obtained：25 species，such as Sapium japonicum，Vitex trifolia var. simplicifolia，Elaeagnus macrophylla，ect，were divided into the first level，most of which have stronger adaptabilities，special ecological functions and multiple ornamental values. Many are local rare and endangered plants，or ancient and famous trees with high values of scientific research or social influence. Pyrus betulaefolia，Acer ginnala，Ardisia japonica，etc，and Prunus dielsiana，Tilia mandshurica，Aralia chinensis，etc，were respectively divided into the second and third level. Comprehensive evaluation can provide reference for the landscape exploitation and application of wild ornamental trees and shrubs in Mount Yuntai or some areas sharing similar climatic type.［Ch，1 fig. 6 tab. 16 ref.］
