基于空间效能的城市生态网络构建*——以亳州市为例

摘要:
[目的]随着我国城镇化进程的不断加快,城市生态要素不断受到侵蚀,构建城市生态网络对城市生态系统保护和修复具有重要意义。[方法]文章基于空间效能的视角,以亳州市为研究对象,运用生态网络连接性、渗透性以及均衡性评价,从生态保护和生态修复两个层面构建城市生态网络。[结果]对“网络本体—影响区—辐射区”不同空间层次的效能进行分析,研究结果表明:在“网络本体”的连接性评价中,生态连接应将河流水系等进行贯通连接,形成城市的生态骨架,并整合破碎的生态斑点,形成规模较大的斑块。“本体—影响区”的渗透性分析表明亳州大部分绿地斑块形状呈现出规则且较为离散的状态。“本体—辐射区”的均衡性评价显示亳州河流水面及沟渠较多且均匀,但是连通性较差。[结论]因此,亳州市应构建包含4个重要生态保护点、3个主要生态修复点和三级廊道体系的生态网络,同时要维持其生态廊道的自然形态,处理好现状保护与建设的关系等方面内容。

Abstract:
With the acceleration of urbanization in China, the urban ecological factors are constantly being eroded and the urban ecosystem is severely damaged. The construction of urban ecological networks is of great significance to the protection and restoration of urban ecosystems. Based on the perspective of space efficiency, this paper took Bozhou city as the research object, and used ecological network connectivity, permeability and equilibrium evaluation to construct the urban ecological network from the two aspects of ecological protection and ecological restoration. By analyzing the effectiveness of the different dimensions of the "network ontology affecting area radiating area", the results showed that river systems should be connected to form an ecological skeleton of the city, and broken ecological patches should be integrated to form larger patches. The analysis of the permeability of the "bulk affected area" showed that most of the patches in Bozhou were a regular and relatively discrete state. The evaluation of the "bulk radiation zone" balance showed that the river surface and ditches of Bozhou city were more and even, but the connectivity was poor. Based on the results of spatial efficiency analysis and combined with the present situation of spatial characteristics in Bozhou city, the ecological network of Bozhou city should be constructed, which includes four important ecological protection sites, three main ecological restoration sites and three level corridor system. It also emphasizes the maintenance of the natural form of the Corridor of Bozhou, the protection of the status quo, and the relationship between the status quo and the construction.
Key words:  spatial efficiency  ecological network  connectivity  equilibrium  permeability
