    关键词:风景园林;生态廊道;城市河流景观;河岸空间模式;河流廊道网络特征

    Key words:landscape architecture; ecological corridor; urban river landscape; bank spatial pattern; network characteristic of river corridor

    摘要:当今城市河流面临生态环境恶化、干扰影响加剧、河流景观匀质化等情况,呈不可持续发展的态势。国内外众多学者对城市河流景观的生态廊道功能和结构的研究已取得一定进展,而对于廊道的三维空间特征综合性研究还未涉及。笔者尝试运用景观生态学理论对河岸景观廊道二维断面空间表征进行模式化归纳,并提出不同模式下的河岸线状绿地匀质空间的优化设计策略,策略考虑了模式的空间、时间特征以及实践指导性;同时,在廊道纵深方向,利用廊道网络特征指数,进行河岸线状绿地匀质空间的网络空间结构定量分析;实现了城市河流景观的生态廊道三维特征辨识与优化,也为多尺度综合研究城市河流景观生态功能提供新视角、新途径。

    Abstract:Today the city is facing environmental degradation, interference increase, homogeneous landscape of rivers, etc. The situation is developing unsustainably. Foreign and domestic scholars have made some progress on the ecological corridor function and structure of urban river landscape. However, the study in three-dimensional characteristics of the corridor has not been involved roundly. The theory of landscape ecology is applied to summarize spatial characteristics of riparian landscape corridor cross-section for two-dimensional and propose riparian green homogeneous space of linear optimization strategy under different modes. The strategies have been considered in the pattern of space, time characteristics and practical guidance. At the same time, in the depth direction of corridor, the corridor network characteristics index is used to analyze the green bank of linear homogeneous space structure quantitatively. Thus, the recognition and optimization of three-dimensional feature of urban river corridor landscape is achieved. It can also provide new perspectives and new ways for multi-scale ecological function of urban river landscape.
