摘要
在对西安园林植物进行23a的观赏物候期及5a的观赏物候相特征观察的基础上,通过对资料的统计分析和整理,绘制了西安地区30种主要季色叶植物的观赏物候期图谱,并描述了它们各观赏物候相特征。通过图谱这种直观的形式并结合特征描述,较为全面地介绍了这30种季色叶植物在西安的观赏物候发生时期及其性状特征,以及各种植物观赏相出现时期之间的重叠、相随及匹配关系。观察结果同时显示,西安地区季色叶植物资源丰富,约有100种,但园林中广泛应用的种类不及1/2;在表现最为突出的30种季色叶植物中,60%为春季兼秋季色叶型,40%为单秋季色叶型。
Based on the data from the observations on ornamental phenophase for 23 years and on ornamental characteristics for 5 years,phenograms of the leaf colors of 30 plants in spring and autumn in Xi＇an were mapped,and the ornamental characteristics were described.It was demonstrated that resources of seasonal colorful plants in Xi＇an were rich,manifested by 100 species.But only half of them were applied in gardens and parks.Among 30 main seasonal colorful plants,60% of them exhibited ornamental values both in spring and autumn,40% of them showed ornamental values only in autumn.
