基于MCR的历史文化景观廊道构建研究——以福州市为例

Construction of Historical and Cultural Landscape Corridors Based on MCR——A Case Study of Fuzhou City

以福州市中心城区为例,选择历史文化景观为源点,采用最小费用路径模型(MCR)和重力模型,构建历史文化景观廊道。基于景观格局理论,分析5、10、20、30、40、50、60、100、120、160、200 m的廊道宽度对区域的影响,确定靠近滨水、道路、公园绿地和山体的廊道适宜宽度。研究结果表明,西湖历史文化风貌区、三坊七巷历史文化街区、上下杭历史文化街区周边的源地联系强度较大,是当前城市规划保护的重点区域;通过最小费用路径提取的廊道与当前规划的廊道基本吻合,部分未被覆盖区域主要集中在仓山区中部;靠近滨水、道路、公园绿地和山体区域的廊道宽度分别设置为30~60 m、5~20 m、30~50 m和30~60 m较为适宜。

This paper selected Fuzhou city as research area and historic cultural landscape as source,and used the Minimum Cumulative Resistance and gravity model to construct the historical and cultural landscape corridors.Based on the landscape pattern theory,the influence of corridor width of 5、10、20、30、40、50、60、100、120、160 and 200m on the area was analyzed,and the appropriate width of corridor near waterfront,road,park green space and mountain was determined.The results showed that the sources contact strength around West Lake-Three Lanes and Seven Alleys-Shangxiahang historic cultural areas was relatively large,which was the key area of the current urban planning;the corridors extracted by the Minimum Cumulative Resistance were basically consistent with the current planning corridors,and some uncovered areas were mainly concentrated in the middle of Cangshan District.The corridor width near waterfront,road,park green space and mountain areas were suitable between 30~60 m,5~20 m,30~50 m and 30~60 m respectively.
