摘　　要：【目的】调查柳州市沿江公园彩叶植物种类及其生长适应性,为柳州以及周边城市滨水绿地的彩化提供参考。【方法】通过现场实地调查、专家咨询以及改良的AHP模型评价法,对柳州市沿江公园彩叶植物种类及适应性进行分析研究。【结果】调查范围内共有乔木、灌木和草本彩叶植物48种,分属32科41属,以乔木和灌木居多。根据色彩在叶面上的分布和观赏期分类,柳州市沿江公园彩叶植物秋色叶类占37.5%,春色叶类(包括新叶有色类)占29.2%,常色叶类与斑色叶类依次为18.8%和16.7%,双色叶类所占比例最小,占4.2%。运用改良的彩叶植物适应性综合评价AHP模型筛选出19种表现好的彩叶植物。【结论】柳州市沿江公园彩叶植物资源丰富,适合岸边湿地的彩叶植物18种;采用改良AHP模型对彩叶植物的适应性进行综合评价,表现好的彩叶植物是引种的种类多于乡土种。[Objective ]Colored-leaf plant varieties and their growth adaptability in Liuzhou riverside parks were investigated so as to provide references for coloring the waterfront green area in Liuzhou and its adjacent cities. [Method]The field investigation, the expert consuhancy and the improved AHP model were applied. [Result]Forty-eight color-leafed species of different kinds of arbor, shrub and herb were found which belonged to thirty-two families and forty-one genera. Arbor and shrub were the majority. According to color distribution and appreciation period,in Liuzhou riverside parks autumn-colorleaf plants occupied 37.5% of the total plants, spring-color-leaf plants （new-colorful-leaf plants） occupied 29.2% of the total plants, and regular-color-leaf plants and brindle-color-leaf plants accounted for 18.8% and 16.7%, respectively. Double-color-leaf plants made up 4.2%, which was the least. Nineteen color-leafed species were selected using the improved AHP model for the adaptability evaluation of color-leafed plants. [Conclusion]Color-leafed plants were rich in resources of riverside parks in Liuzhou. Eighteen color-leafed species were suitable for wetland shore. Based on the results of the modified AHP model, the performance of introduced varieties were superior to that of the local ones.
