城市滨水绿地植物空间模式

A Study of Plant Space Pattern at the Waterfront Region

滨水绿地设计的核心内容之一是研究留出适宜观水的视线通廊,而在城市生态建设中水景常被绿地阻隔。以徒骇河聊城城区段景观绿地为例,通过分析限制因素,以场地内的乔木、灌木、地被为基本材料,采用计算机辅助模拟的方法,研究种植密度、种植区域的差异对观水尺度的影响,分别对不同植物空间下游人看到的水景尺度进行了深入研究。结果表明,3类植物对于水景的阻隔程度为:灌木>乔木>地被,并提出适于聊城市徒骇河滨水绿地植物空间的观水景模式。

One of core issues in waterfront green spaces is to leave proper sight cmTidor for waterscape watch, but the waterscape is often blocked by green spaces in urban ecological construction. Taking the landscape green space of Tuhai River in urban area of Liaocheng as an example, the paper studied the effect of the variation of planting density and planting area on the scale of visible waterscape by analyzing limiting factors and with trees, shrubs and ground covers as the basic materials. It also conducted a further study about waterscape scale that tourists could observe under different plant spaces using computer aided simulation method. The results indicated that the degree of blocking waterscape of the three types of plants was as follows ： shrubs 〉 trees 〉 ground covers. The plant space patterns which were suitable for green spaces of Tuhai River in urban Liaocheng were therefore put forward.
