Ornamental Evaluation of 14 Wild Plant Species with Seasonal Coloration Based on AHP in Gansu Province
[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
