| Abstract: | ]An evaluation index system for afforestation species of ecological landscape construction was established in terms of eco adaptation, ornamental value, resistance, and ecological benefit according to the Delphi method. An importance weights evaluation method was initial established by the analytic hierarchy process considering the relative level of experts and the entropy technology. According to the weight calculation method, the evaluation and selection model of afforestation species of ecological landscape construction was preliminary established. Twenty tree species which were worth promoting in Zhuhai were selected by this evaluation model. |
