浙中地区野生观赏攀援植物资源调查与分析

Wild ornamental climber resources in central Zhejiang Province

在研究国内攀援植物资源调查和分类方法的基础上,提出了“野外观察认为观赏价值较高,且具备2种以上观赏内容或园林用途者,文献资料记载有观赏价值或已有利用者,具特殊园林用途或观赏效果者”等3项野生观赏攀援植物资源调查与筛选原则,并按照树木观赏部位,将野生观赏攀援植物资源划分为观花类、观果类和观叶类等3个大类,每大类分常绿和落叶2个小类。对浙江中部地区的野生观赏攀援植物资源进行了调查与筛选。浙中地区有野生观赏攀援植物约17科27属52种,其中观花类33种(常绿19种,落叶14种),观果类6种(常绿和落叶各3种),观叶类13种(常绿5种,落叶8种),分别列出它们的观赏特性和园林用途。还分析了浙中野生观赏树种资源的特点,提出开发利用与保护意见。

Despite it being a plentiful resource, there has been no research conducted on wild ornamental climbers in central Zhejiang Province. The purpose was to analyze and evaluate the ornamental characteristics of wild ornamental climber resources in central Zhejiang Province and to put forward suggestions for their exploration, utlization, and protection. Based on a typical survey and classification methods for these wild ornamental climbers, three groups in central Zhejiang Province were established. These were wild ornamental climbers 1 ） with comparatively high ornamental value observed int he field with two or more ornamental functions or garden purposes, 2） that have an ornamental value recorded in the literature or that are already being utilized, and 3） with special garden purposes or ornamental effects. The three groups of wild ornamental climbers were divided into three classes according to their ornamental flowers, fruits, and leaves. Each of these three classes was then subdivided into evergreen and deciduous categories. Results of the field survey indicated that there were 52 species of wild ornamental climbers, belonging to 27 genera of 17 families. Among these, 33 were ornamental flowers （19 evergreen and 14 deciduous）, 6 were ornamental fruits （3 evergreen and 3 deciduous）, and 13 were ornamental leaves （5 evergreen and 8 deciduous）. Ornamental characteristics and garden purposes of the wild ornamental climbers were also listed. [ Ch, 3 tab. 19 ref. ]
