基于孤岛化分析的南阳市府衙街区传统地域文化景观保护

Protection of Nanyang′s Magistrate Office Blocks′Traditional Territory Cultural Landscape Based on the Analysis of Islanding

随着城市化加速发展,破碎化斑块已经成为城市传统地域文化景观的主要空间特征与形态。以南阳府衙街区为研究对象,通过孤岛化指数评价发现,南阳府衙街区处于明显的孤岛化状态,并且无限趋近于严重孤岛化状态。通过景观点、景观线以及景观面三个层次构建“圈层+廊道”的传统地域文化景观保护体系,降低该区域的孤岛化指数,逆转孤岛化现象,恢复传统景观空间格局的完整性和延续性。

With the acceleration of urbanization development,fragmentation patches has become the main spatial feature and form of urban traditional territory cultural landscape.Taking Nanyang′s Magistrate Office Blocks in Nanyang City as the research object,through the landscape islanding index evaluation,it is found that the Nanyang′s Magistrate Office Blocks is in a state of obvious islanding,and it is infinitely approaching a serious islanding state.The traditional territory cultural landscape protection system of′circle+corridor′is constructed through the 3 levels of landscape points,landscape lines and landscape surfaces to reduce the islanding index in the area,reverse the islanding phenomenon,and restore the integrity and continuity of the traditional landscape spatial pattern.
