包头市论文：包头市几种园林花灌木的引种效果分析 【中文摘要】本研究通过对16种花灌木的研究,全面观察引种树木的适应性、观赏性、生长特性,应用层次分析法对引种植物进行综合评价。根据引种植物的特点,建立了递阶层次结构评价模型,分为4层,即目标层、约束层、标准层和最低层。目标层是根据人们的审美意识以及树木的生物学特性确定我们在进行植物造景时引种植物所达到的要求。本评价系统选择对植物景观应用价值影响较强的观赏性状、适应性状及生长性状三个因素作为对目标层的约束层。标准层是体现约束层的具体评价指标,共计14项,从而构成一个多层次的分析结构模型。最低层为待评的16种花灌木。应用层次分析法分析,适应性强的树种有银露梅、金露梅、珍珠绣线菊、三亚绣线菊、土庄绣线菊、四季玫瑰、阿若红忍冬;观赏性好的树种有三亚绣线菊、红王子锦带、金露梅、珍珠绣线菊、金叶裂叶接骨木、金叶锦带、花叶锦带、紫叶锦带;生长势好的树种有珍珠绣线菊、阿若红忍冬、四季玫瑰、金叶锦带、金叶裂叶接骨木。应用层次分析法综合评价,应用价值高和较高的灌木有珍珠绣线菊、三亚绣线菊、金露梅、四季玫瑰、银露梅、土庄绣线菊、阿若红忍冬、金叶裂叶接骨木,可以在包头推广使用。应用价值一般的植物如金叶山梅花、金叶风箱果、金叶锦带、花叶锦带、紫叶锦带、红王子锦带,在小气候较好,可以在精细管理的地段使用。价值较低的种类如木绣球、平枝栒子不能在包头地区使用。 【英文摘要】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
