数字化视野下的江南水网地区城市滨水用地规划研究

The river system is the core of the traditional Canal Town in the lower reaches of the Yangze River. Water area and land area are distributed alternately and closely interconnected. Nevertheless, in large-scale contributions The very geographical spatial pattern of the city is fading out. The digitization is a trend for future urban planning. The digital method is skilled in logic analysis and dealing with mass data reasoningly and objectively. This research is focus on the application of digital analysis to study the Water Front Spaces of regions south of the Yangtze River famous for water system. Basing on the research of the isomorphism form of water-system and urban-land-system in traditional Jiangnan Watertown, it is pointed out the key point of the isomorphism of water-system and urban-land-system should focus on the planning of water front spaces with the precondition regaining public character of therm..Digitization of urban planning has the advantage of logical analysis and mass data processing, with rationality and impersonality. The research is to apply digitization to study of the water front area of lower reaches of the Yangze River that famous for water system. The study exploits digitization analysis in steps. Firstly, base on the public character of the function of the area, the relation between land area and the distribution of the river system can be classified into 3 characters, suitable, compatible, and repulsive to support computer analysis and calculation. Secondly, we propose some solutions, verify rationality of the analytical method, then, and improve the research plan to carry out the best distribution linking theory with practice..Then urban regeneration of water front area can be guide in a more reasonable way, in the perspective of digitization. for the area with the character ‘suitable’, the urban waterfront area can be guided by choosing suitable function; for the areas with the character ‘compatible’ and ‘repulsive’, it can be adjusted by the means of Segmentation and replacement, polarization and induction, vectoring and transformation..

传统江南水网地区城市是以水网为核心，水陆相生相依。而在大规模城市建设中，极具地域特色的城市空间格局正逐步消逝。课题通过对江南城镇“水陆同构”空间原型的研究，认为恢复“水陆同构”关键在于城市滨水用地的规划，前提是恢复滨水用地的公共开放性。. 城市规划数字化研究善于逻辑分析和处理海量数据，理性而客观。研究将数字化分析应用到江南水网地区城市滨水用地的研究中。根据滨水用地的公共开放性与否的原则，将地块与水的关系分为适宜、兼容、排斥三种逻辑关系，以利于计算机分析处理。按提出设想，分析验证，调整方案的步骤最终得到理论和实际耦合程度最高的分类方法。. 进而在数字化视野下对城市滨水用地进行多项分析研究：控制滨水地带中适宜、兼容、排斥各类别的比例和分布；并且通过置换、分割替换、分化归纳、引导转换等手法更新调整滨水用地，重构水与城市的联系。

传统江南水网地区城镇在其历史发展过程中高度依赖河道水网，城镇空间格局与河道水网相生相依，形成极具地域特色的城市意象。然而随着近现代城市生产生活方式的改变，快速城市化进程中城市空间结构发展逐渐脱离水域，造成大比例滨水空间功能不适宜、公共开放性丧失、结构尺度失调、交通可达性差。直接削弱了滨水空间中人的活动，衍生了滨水意象的破败。. 研究在城市总体规划的大格局下，选择从城市控制性详细规划、城市设计层次入手，围绕江南水网地区城市滨水空间与街区结构之间的关系展开定性、定量研究。着重分析了滨水空间与街区土地功能属性、街区开放与否属性、街区尺度结构、滨水可达性等方面的联系。此外也进行了一些子项目研究，如江南城市传统与现代空间格局、滨水环境评价、滨水空间城市设计、互联网数据分析处理、地域建筑教育等。. 研究秉承定义明确、界定清晰、程序固定的原则，以定量分析形成数字化成果说明问题。在各环节中多采用先定义，后分类，再综合的程序。通过互联网辅助收集数据，通过GIS、空间句法等软件分析数据，利用多因子加权叠加法、层次分析法等建立评价体系。从而体现了数字化的分析思路。. 在理论研究基础上，以恢复滨水空间中人的活动为根本目的，对滨水空间的更新和修补提出了相应的策略方法。包括：功能属性的更新，由封闭改造为开放，街区内部滨水界面联通，相邻滨水街区联通、缩小街区尺度、滨水区的分割和置换、分化和归纳等。可为规划设计单位和政府管理部门的相关工作提供参考信息和操作思路。. 研究周期内积极发表学术论文、参加学术交流、辅导学生科研和论文、完成人才培养、获得奖项，成果的数量和质量达到并超出了申请时所列的成果要求。
