银川市公园园林植物调研及其应用分析

Investigation and Application of Garden Plants in Parks of Yinchuan City

为促进银川市城市公园园林植物应用中对于本地树种的保护、开发和利用,按照公园绿地划分标准选取了银川市3个区3种不同类型共9个城市公园,采用实地调查的方式,并查阅相关公园植物配置资料及地理位置资料,对公园园林植物配置种类、分布状况、配置结构以及养护状况等方面进行了调查。结果表明:银川市城市公园现有主要园林植物134种,分属62科,103属;其中,蔷薇科植物应用广泛,共计16种;乡土树种共计75种,引种树种59种,其比值为1.3∶1.0;从银川市城市公园园林植物观赏效果来看,观花类乔木、灌木共计79种。基于调查分析结果建议:在未来城市公园发展过程中,继续推广蔷薇科植物的应用,推荐沙枣等为本地特色树种,侧柏、毛白杨等为城市公园园林绿化骨干树种。此外要加强对抗逆性强、具有特殊观赏价值树种的利用,增加城市公园园林植物植物种类的多样性,增加常绿树种,优化树种的结构与组成,加强对园林植物的栽培,发掘本地树种,增强地域风情特色。

In order to promote the protection,development and utilization of local tree species in the application of garden plants in urban parks of Yinchuan City,according to the standard of park green space division,9 city parks with 3 different types in 3 districts of Yinchuan city were selected.By means of field investigation and consulting the relevant park plant configuration data and geographical location data,the park garden plant configuration types,distribution status and configuration structure were analyzed,as well as the maintenance status and other aspects of the investigation.The results showed that,there were 134 species of main garden plants in urban park of Yinchuan City,belonging to 62 families and 103 genera;among them,Rosaceae plants were widely used,with a total of 16 species;there were 75 species of native tree species,59 species of introduced tree species,with a ratio of 1.3∶1.0;from the ornamental effect of garden plants in urban park of Yinchuan City,there were 79 species of ornamental trees and shrubs.Based on the results of investigation and analysis,it is suggested that the application of Rosaceae plants should be promoted in the future development of urban parks,and Elaeagnus angustifolia and other local characteristic tree species should be recommended,while Platycladus orientalis and Populus tomentosa should be the backbone tree species for urban park landscaping.In addition,we should strengthen the use of trees with strong resistance and special ornamental value,increase the diversity of garden plants in urban parks,increase evergreen tree species,optimize the structure and composition of tree species,strengthen the cultivation of garden plants,explore local tree species,and enhance regional characteristics.
