| In this paper, the adaptation traits, ornamental characteristics, and growth traits of 16 introduced ornamental bushes were evaluated by means of AHP (Analytic Hierarchy Process).According to the feature of the introduced plants, the evaluation model of hierarchical structure, which included 4-levels, was established. These are target layer, constrained layer, standard layer and the bottom. The target layer is that we made our demand in the introduction plants'sight building according to people's aesthetic and biological characteristics. In this evaluation system, the three main factors that included ornamental characteristics, adaptation traits and growth traits were selected as constrained layer. The standard layer is the specific evaluation index, and included 14 items. The bottom is the 16 introduced bushes to be evaluated.By means of AHP, the Potentilla glabra Lodd, Potentilla fruticosa(L) Rydb, Spiraea thunbergii Sieb. ex Blune, Spiraea trilobata L, Spiraea pubescens Trurcz, Rosa rugosa cv. Duoji, and Lonicera have good adaptability. The Spiraea trilobata L, Weigela florida Red Prince, Potentilla fruticosa(L) Rydb, Spiraea thunbergii Sieb. ex Blune, Sambucus canadensis cv. Aurea, Weigela florida cv Aurea, Weigela florida Variegata, and Weigela florida Ziye have good ornamental characteristics. The Spiraea thunbergii Sieb. ex Blune, Lonicera, Rosa rugosa cv. Duoji, Weigela florida cv Aurea, and Sambucus canadensis cv. Aurea have good growth traits.By means of comprehensive evaluation with AHP, the Spiraea thunbergii Sieb. ex Blune, Spiraea trilobata L, Potentilla fruticosa(L) Rydb, Rosa rugosa cv. Duoji, Potentilla glabra Lodd, Spiraea pubescens Trurcz, Lonicera, and Sambucus canadensis cv. Aurea have high using value, and can be introduced and used in Baotou City. The bushes with medium using value are Philadelphus incanus, Physocarpus opulifolius cv. Darts Gold, Weigela florida cv Aurea, Weigela florida Variegata, Weigela florida Ziye, and Weigela florida Red Prince. These bushes could be grown under mild micro-climate or environment in Baotou City. The Hydrangea bretschneideri Dippe and Cotoneaster horizontalis Dcne have lower using value, and can not be used in Baotou region. |
