肇庆高新区道路绿化调查及其优化对策研究

文章调查了肇庆高新区道路绿化的19个样地，结果显示，园林植物共计56科106属148种，其中，乡土树种共计26种；乔木、灌木、草本之比为2.96：2.48：1；常绿与落叶植物比例，乔木层为2.23：1，灌木层为6：1；观花、观果、彩叶植物分别占42.6%、6.1%、18.9%；植物种植形式以自然式种植为主，垂直结构主要有3种类型。在此基础上，探讨了道路绿化优化的策略，建议加强绿地规划布局的科学性，构建多种景观类型；丰富植物种类，确定园区27条主要道路的主调树种，做到“一路一树一景”，为该区道路绿化建设提供参考。

Research on Landscape Surveying and Optimizing of the Urban Road in Zhaoqing Hi-tech Industrial Development Zone

The result of this paper shows that there are 56 families, 106 genera and 148 species of landscape plants in total through investigating 19 sample plots of road greening in Hi-tech Industrial Development Zone of Zhaoqing city. Among vegetations, the number of native species has 26 species in total; the ratio among trees, shrubs and grasses respectively is 2.96：2.48：1;for the layer of trees, the ratio of evergreen to deciduous trees is 2.23：1;for the layer of shrubs, the ratio of them is 6：1;the percentage of flowering plants, fruiting plants and colorful plants in all vegetations , respectively, is 42.6%, 6.1%and 8.9%;for forms of trees planting, naturalistic planting is given priority to; the vertical structure of plants have three main styles. On the basis of these, the joint efforts of discussion about optimized strategies of road greening, suggesting about enhancing the scientific green space planning and layout, constructing a variety of styles of landscapes, enriching plant species, and putting forward to plant predominant trees in 27 main roads of the region are to strive for the purpose of the characteristic landscape of one specific species planted in a road, and also providing some suggestions for construction of road greening in this region.
