摘要: 针对总体城市设计中面临的郊野地区地域景观特征认知和设计导控问题，提出一种以“水系肌理”为切入点的基础分区方法。依托水系资源所具有的单要素、跨区域和整体覆盖的特点，形成一种以水系指标的数据分析来识别水系形态特征的分区方法。以上海市域为研究对象，选取7项形态相关指标。通过单因子栅格测评、相关性分析，筛选出不同维度的3项关键性指标，即反映规模特征的水面率指标、反映分布密度特征的岸线密度指标和反映水系复杂程度的分维指数。通过对关键性指标的栅格化测评、聚类和归并，提出上海市域范围内总体城市设计基础分区的初步建议，探讨平原河网地区水系肌理总体城市设计分区方法的可行性和局限性，并提出后续完善建议。
Abstract: Aiming at the problems of cognition and design guidance of regional landscape characteristics in rural areas in overall urbandesign, a basic zoning method based on "water texture" is proposed. Relying on the characteristics of water resources, thispaper forms a zoning method to identify the morphological characteristics of water system based on the data analysis ofwater system indicators. Taking Shanghai as the research object, seven morphological related indicators are selected. Throughsingle-factor grid evaluation and correlation analysis, three key indicators of different dimensions are selected, namely, thewater surface ratio reflecting the scale characteristics, the shoreline density reflecting the distribution density characteristics,and the fractal dimension index reflecting the complexity of the water system. Through the grid evaluation, clustering andmerging of key indicators, this paper puts forward a preliminary proposal on the basic zoning of overall urban design inShanghai, discusses the feasibility and limitations of the overall urban design zoning method of "water texture" in plain rivernetwork area, and puts forward follow-up improvement suggestions.
