张掖城市空间形态演变及城水关系研究

基于航拍影像图和古籍文献数据,采用空间数据分析方法,研究1949—2012年张掖市城市空间形态动态演变规律及城水互动关系.结果表明:城市由缓慢发展转向快速发展,土地集约利用率提高.城水关系由远至近,由被动到互动,水系的城市生态功能日益凸显,水环境被赋予了更加丰富的内涵.基于可持续发展与水生态建设相协调的发展目标,未来张掖应从整治城市河道水系、构筑水生态安全格局,以及修复保护城市湿地、加强生态绿地建设等策略入手,打造城市水文化名片,推进城市可持续发展.

Study on the evolution of urban space form and the relationship between city and water in zhangye city

Based on the aerial imagery and ancient literature data, the spatial data analysis method was used to study the dynamic evolution of urban spatial morphology in Zhangye City from 1949 to 2012. The results show that: The city has changed from slow development to rapid development, and the land intensive utilization rate has increased. The relationship between city and water is from far to near, from passive to interactive, the urban ecological function of the water system is increasingly prominent, and the water environment has been given more rich connotations. Based on the goals of sustainabledevelopment and water ecological construction, in the future, Zhangyeshould renovatethe river system, construct the water ecological security pattern, repair and protect the urban wetland and strengthen the ecological green space construction to create the water culture characteristic, and to promote sustainable development.
