    摘要:在全球经济快速发展和中国快速城市化的背景下,城市水系空间的生态安全与文化传承受到了前所未有的冲击。基于城市水文生态安全与景观特征评价的理论和方法,以安徽省宁国市中心城区水系空间为例,以城市水文生态风险评价(ERA)与城市水系景观特征分析(LCA)评价为主要技术手段,探索通过水系空间淹没区分析、水系潜在污染源分析、城市水系空间景观文化特征识别与分析、景观视觉敏感度分析与景观文化价值分析,将城市水文生态安全控制与城市水系景观文化传承和创新有机结合的水系空间组织方法。

    Abstract:The ecological safety and cultural heritage of urban river space are challenged with the global economy development and rapid urbanization. Based on the theories and methods of urban hydrographic ecological safety and landscape character assessment, taking the river space of the central urban area of Ningguo City as an example, the research analyses the river space submerged area, and the potential pollutant sources, identifies and analyses the urban river space landscape cultural character, and analyses the landscape visual sensitivity and cultural value. Focused on ecological risk assessment (ERA) and landscape character assessment (LCA), the study illustrates the river space organization method which combines urban hydrographic ecology and safety control and urban river cultural heritage and creativity.
