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。把握河流水系特有的单一要素、跨区域流动和整体覆盖的特点,借鉴水资源研究中形态的相关指标,构建一种以水系为指标的数据分析来识别水系形态特征的分区方法。本文以上海市域为研究对象,选取三项不同维度的关键指标,即水面率、岸线密度和分维指数,对全域的水域规模、分布密度及复杂程度展开单因子栅格化数据分析。通过进一步聚类和归并后,提出上海市域范围内郊野地区总体城市设计的基础分区建议。通过对下一层次的浦东新区范围内河流水系在不同范围边界、不同栅格尺度和不同因子测评验证和反馈,探讨“水系肌理”作为总体城市设计空间分区方法的可行性和可靠性,并提出后续完善建议。Aiming at the problems of cognition and design guidance of regional landscape characteristics of countryside in overall urban design,a basic zoning method based on“water texture”is proposed.By grasping the unique characteristics of single element,cross regional flow and overall coverage of river water system,and drawing lessons from the relevant morphological indicators in water resources research,this paper studies and constructs a zoning method to identify the morphological characteristics of water system based on the data analysis of water system indicators.Taking Shanghai as the research object,this paper selects 3 key indicators representing different dimensions,namely water surface ratio,shoreline density and fractal dimension index,and carries out single factor grid data analysis on the water area scale,distribution density and complexity in the whole region.Through further clustering and merging,this paper puts forward the basic zoning suggestions for the overall urban design of rural areas in Shanghai.Through the verification and feedback of different ranges,grid scales and factors of the river water system in Pudong New Area at the secondary level,this paper discusses the feasibility and reliability of“water texture”as a spatial zoning method of overall urban design,and puts forward follow-up improvement suggestions.
