摘　　要：为挖掘陕西省榆林地区的观果植物资源,通过实地调查法对榆林市观果植物资源进行全面调查,从中选取榆林地区常见的50种观果植物为研究对象。运用层次分析法(AHP)构建榆林市观果植物综合评价体系,从观赏价值、开发利用潜力、生物学特性3方面选取12项具体指标对观果植物进行综合评价,根据综合评价得分划分等级。结果表明,垂丝海棠、山荆子、山楂等10种植物观赏价值高,被划分为I级观果植物;红宝石海棠、平枝栒子、榆叶梅等15种观赏价值较高,划分为Ⅱ级;水蜡、翅果油树、天人菊等16种观赏价值一般,划分为Ⅲ级;掌裂叶蛇葡萄、角蒿等9种观赏价值较低,划分为Ⅳ级。并依据综合评价结果,结合观果植物的观赏特性、景观营造效果等,推荐了适宜大量开发应用的观果植物种类。In order to find out the ornamental fruit plants resources in Yulin area of Shaanxi Province,a comprehensive survey of ornamental fruit plants resources in Yulin city was carried out by field investigation.Fifty common fruiting plants in Yulin area were selected as the research objects.The analytic hierarchy process(AHP)was used to select 12 specific indexes from three aspects of ornamental value,development and utilization potential and biological characteristics to comprehensively evaluate the fruiting plants.The grades were classified according to the comprehensive evaluation scores.The result showed that the ornamental value of 10 fruit plants,such as Malus halliana,Malus baccdta and Crataegus pinnatifida,was much higher,and they were classified as grade I.The ornamental value of 15 kinds of Malus micromalus cv.“Ruby”,Cotoneaster horizontalis and Ulmus pumila are high,and they are classified into as gradeⅡ.The ornamental value of 16 species,such as Ligustrum obtusifolium,Elaeagnus mollis and Gaillardia pulchella,was general and classified into gradeⅢ.The ornamental value of 9 species,such as Ampelopsis delavayana,Incarvillea sinensis,was low,and they were classified as gradeⅣ.Based on the comprehensive evaluation results,combined with the ornamental characteristics and landscape construction effects of fruit plants,the fruit plant species suitable for large-scale development and application are recommended.
