Abstract:[Objective] To investigate and analyze wild plant species with seasonal coloration around Lanzhou City in order to select the ornamental species from wild seasonal coloring species suitable for landscape in the semi-arid regions of Gansu Province.[Methods] Firstly, the integrative evaluation model of wild plant resources with seasonal coloration was set up based on 5 evaluation criteria(overall feature C1, foliage value C2, ornamental flower C3, fruit value C4 and adaptation C5) and 17 evaluation indicators. Then, the 14 kinds of wild plant species with seasonal coloration were evaluated by the method of analytic hierarchy process. Finally, they were divided into different levels based on the evaluation result.[Results] ① Among the 5 evaluation criteria, C5 had the biggest constraining force to destination layer. ② Among the 17 evaluation factors, crown aesthetic(P1), leaf colour(P5), cold resistance(P15) and heat resistance(P16) provided most of contribution to ornamental value. ③ The comprehensive assessment levels were divided into three levels.[Conclusion] The first level included 3 species, which were Acer tetramerum, Quercus wutaishanica and Sambucus adnata. The second level included 5 species that were Berberis kansuensis, Berberis brachypoda, Berberis diaphana, Cotoneaster multiflorus and Cotoneaster acutifolius. The third level included 6 species, such as Berberis potaninii, Lespedeza formosa, Quercus aliena, Swida bretschneideri, Daphne giraldii and Coriaria nepalensis.
