广州市生态景观林带建设树种筛选评价

Screening and Evaluation of Plants for Ecological Landscape Forest Belt Construction in Guangzhou

基于广州市生态景观林带特色,建设场地及植物应用现状分析,采用层次分析法对初筛的200种广州地带性乡土植物进行了综合评价。综合评价模型由适应能力、应用价值、观赏效果、开发潜力4个评价准则及相关的13个评价因子构成。建议：综合得分在89以上的17种地带性乡土植物可作为林带的基调树和主景树;88~87分的可广泛开发利用;87~85分的可适度开发利用;85~83分的可选择性开发使用;低于83分的暂不推荐开发利用。研究结果可为广州市生态景观林带建设的树种选择提供科学参考,研究方法和模型可为其他特定生境植物筛选提供借鉴。

Based on the study of characteristics of ecological landscape forest belt in Guangzhou, construction sites and utilization status of plants, the authors synthetically assess the preliminarily screened 200 regional wild plant species by analytical hierarchy process（AHP）. The synthetic assessment model is made up of 4 evaluation criteria – adaptability, application value, ornamental effect and exploitation potential, along with 13 related evaluation factors. The results demonstrate that 17 regional wild species scored over 89 points have the potential of being used as the dominant tree or accent plant for the ecological landscape forest belt, those that scored between 87-88 points can be widely utilized, and plants scored between 85-87 points are suggested to be exploited moderately, while species scored between 83-85 points are recommended to be considered selectively, and those that scored under 83 points are temporarily excluded. The results can provide scientific suggestions for tree species selection in establishing the ecological landscape forest belt for Guangzhou. Meanwhile, the methods and model may also offer reference for plant species screening in other specific habitats.
