三角洲适应性转型——基于景观的区域设计方法

针对气候变化和城市化对富饶的三角洲地区带来的洪涝风险、生态、社会—文化价值流失等威胁，提出将三角洲城市化进程视为一系列具有独立动态特征和速率变化的复杂社会—生态系统（子系统），急需为保障该类型区域的可持续发展提供空间战略，以协助修复系统漏洞并增强应对自然和人工威胁的能力，以珠江三角洲为例，针对城市化进程中三角洲区域的适应性城市转型，提出基于景观的区域设计方法。通过对自然和城市景观要素转型性循环的各类动态变化进行评估，得到生态动力型区域设计战略，为城市化进程中的自然和社会—文化发展提供更多机遇。提出保障水安全和全纳性社会—生态设计的适应性转型视角。

Towards a Landscape-based Regional Design Approach for Adaptive Transformation in Urbanizing Deltas

Deltaic areas are among the most promising regions in the world. Their strategic location, combined with the superior quality of their soils, constitute the main factors that have been supporting both human development and the rise of these regions as global economic hubs. At the same time, however, deltas face extreme vulnerability due to multiple threats related to both climate change and urbanization. These threats include an increasing amount of flood risk, combined with the loss of ecological and social-cultural values as a result. The urbanization of deltas can be understood as a set of complex social-ecological systems (and subsystems), each with its own dynamics and speed of change. To ensure a more sustainable future for these areas, spatial strategies that strengthen resilience are needed that can assist the systems to not only cope with their vulnerabilities, but also to strengthen their capacity to face natural and artificial threats. Therefore, this article elaborates a landscapebased regional design approach for an adaptive urban transformation in urbanizing deltas, using the Pearl River Delta as a case study. Based on an assessment of the dynamics of change regarding the transformational cycles of natural and urban landscape elements, eco-dynamic regional design strategies are explored in order to provide more opportunities for natural and social-cultural aspects within the processes of urban development. Furthermore, adaptive transformational perspectives are identified to ensure water safety and inclusive socio-ecological design.
