昆明市小游园绿化景观植物资源调查研究

Investigation of Small Garden Greening Plants Resources in Kunming

以昆明市小游园为研究对象,调查其绿化植物资源及数量等状况,提出植物名录.分析小游园植物资源的特点,认为小游园虽然比行道树的绿化植物种类多,但总体上植物种类仍较单一,仅有123种,其中竹类仅有4种,缺乏本土文化特色.建议以乡土树种为主、外来引种为辅,多开发观赏特性和生态效益较高的植物;在观花植物基础上,增加观果、垂直绿化植物的种类,并突出本土植物文化特色.

In this study, plant resource of small gardens in Kunming was investigated and categorized with the reference of the plant species database. Meanwhile, the character of plant resource was analyzed. Result showed that although the small garden plants were a little more complicated than that of the street trees, the plant composition of the small gardens was quite simplistic, as there were only 123 plant species in the small gardens, four of which were bamboo species. Small gardens were devoid of native species and dominant with invasive species. Suggestions were made as the following： First, the small gardens should be designed to be dominant by native species; exotic species could be introduced as comple- ments. Secondly species with high decorative and ecological values should be preferentially developed and cultivated. Furthermore, more concern should be put on plants with ornamental flowers. Meanwhile the amount of vertical climbing plants and plants with ornamental fruits should be increased. Finally, emphasis should be laid on the distinguished species that represent local ethnic cultures.
