| 摘 要： | 为探究影响植物景观质量的核心成分，以南京市6所高校校园为研究区域，192处植物景观样地为研究对象，对植物景观的植物种类进行统计以及使用美景度法对景观质量评价。在调查112名公众的基础上，获得了25个景观质量评价因子，对因子进行主成分分析。研究统计出6所高校植物景观共涉及99种植物，筛选出各所高校植物景观质量评价前1的样地作为校园景观提升与城市绿化的优先选择。经过主成分分析，前5个特征值的累积贡献率为86.203%，超过85%，可以较好地表达出原有25个要素因子的总体变化，从而构建出植物景观质量的特征指数；在此基础上，进一步分析了植物景观不同要素因子和特征指数与景观质量等级之间的关系。最后对植物景观营建工作提出注重植物色彩品质、审美艺术性、挖掘植物文化以及选择亲民、乡土植物等几点建议。

| Abstract: | In order to explore the key components that influence the plantscape quality,192 sample sites of the representative plantscape were selected from the campuses of six universities in Nanjing to conduct the statistics of the plant species and to carry out the evaluation of plantscape quality by using the landscape beauty method.Based on the survey of 112 individual members from the public,25 landscape quality evaluation factors were obtained,from which the principal component analysis was carried out.According to the research and statistics,there existed 99 plant species in the campuses of six universities.After evaluation,one best sample site of plantscape was selected from each university campus as the priority choice of plantscape promotion and urban greening.Through the principal component analysis,the first five characteristic value of cumulative contribution rate was 86.203%,more than 85%,which could better express the overall change of the original 25 factorss,and plantscape quality indexes were established.On this basis,the relationship between different factors and characteristic indexes and the degree of beauty were further analyzed.Finally,some suggestions on plantscape construction were put forward from the aspects of emphasizing the quality of plant color,aesthetic art,scenic forest culture and the choice of rural plants. |
