韧性:三角洲地区规划转型的新理念

Resilience as a New Concept of Planning Transformation in Delta Areas

  • 摘要: 三角洲地区经过近几十年的快速发展,在城市建设方面取得举世瞩目的成就,然而长期积累的生态问题也更加突出,暴露出的空间脆弱性问题日益显著。面对自然基底脆弱、自然灾害扰动趋势增强等因素在时空上的高度叠合,迫切需要提升三角洲地区应对未来不确定性扰动的能力。首先从景观角度分析三角洲地区自然环境的特殊性,提出韧性规划是对现有三角洲地区规划转型的论点,认为鲁棒性、适应性、学习—转化能力是三角洲地区韧性规划的核心能力,系统性、协同性、底线性、预判性是三角洲地区韧性规划的主要思维特征。其次,进一步从优化整体格局、构建流动性载体、加强对韧性技术策略的研究和应用、重视跨尺度协作与管理等方面提出了构建“格局—连通—关键点”的韧性规划框架。最后,阐述韧性规划作为三角洲地区规划转型的新理念,应用于具体案例的空间布局时须以人为本,依托自然环境,以自然流动性为规划导向;须基于预判式过程,充分构想能够应对不同情景的预案;须整合生态智慧与现代技术,明晰兼顾鲁棒性与适应性的功能分区管治体系。

     

    Abstract: Delta areas have made remarkable achievements in urban construction, as a result of rapid development in recent decades. However, the accumulated ecological problems have also become more prominent, exposing challenging obvious spatial vulnerability problem. In the face of the high overlaps of factors such as fragile natural basement and increased spatial-temporal disturbance of natural disasters, there is an urgent need to improve the ability of delta areas to cope with future uncertain disturbances. This paper first analyzes the particularity of natural environment in delta areas from the perspective of landscape, and proposes that resilience planning is the transformation of existing planning in delta areas. It believes that robustness, adaptability and learning/transformation ability are the core capabilities of resilience planning in delta areas, while systematic, integrative, baseline and scenario thinking are four major principles toward resilience. Secondly, it further puts forward constructing the resilience planning framework of “pattern-connectivitystrategic points” of multiscale delta space from the aspects of highlighting the overall land use pattern, constructing flowspace carriers, strengthening research and application of resilience technologies, and stressing effective cross-scale cooperation and management. Finally, it expounds the points that need to be paid special attentions in real practice when taking resilience planning as the new concept of planning transformation in delta areas. That means, a new proposed spatial layout can not only overcome shortages deriving from the overview of history and evaluation of existing site, but also cope with different scenarios with different development and risk degree. When applied this concept to distribute spatial layout of a specific case, it is required to rely on the natural environment, taking dynamic landscape process into consideration. It is also necessary to integrate ecological wisdom and modern technologies, managing guidelines with robust and adaptive functional zones and typical sections.
