龙舟竞渡是中国家喻户晓的传统文化活动，也是国家积极推动进入夏季奥运会的体育项目。但对于龙舟竞渡空间环境尚未形成系统研究，存在以“赛龙舟”一类非空间概念指代龙舟竞渡空间环境的现象；同时，伴随我国城乡发展的深化，人水关系和谐发展对公共水域使用内容提出了新需求。本研究在此背景下展开，旨在从空间视角界定龙舟竞渡场及相关概念，并对龙舟竞渡场的空间形态互动机制进行理论建构和不同维度的分析阐释。首先，对龙舟竞渡场进行明确的定义：在当代城市或乡村公共空间中进行群众参与的龙舟竞渡的场所，一个完整的龙舟竞渡场包括竞渡水域和竞渡陆域。其次，总结现有龙舟竞渡空间研究存在的问题，借助社会网络分析、文化拓扑学、关系地理学的相关理论，将水系作为形态基础的社会关系互动过程纳入龙舟竞渡场空间形态生成机制中，建构滴网结构理论。在此基础上，研究从5个维度展开分析，第一，细化现有龙舟竞渡发展断代，并对龙舟竞渡场滴网结构现代化过程进行阶段划分；第二，基于6997条地方志信息建立的数据库，揭示中国龙舟竞渡场的分布规律，从滴网结构视角分析其分布特征；第三，基于190个非遗龙舟竞渡场和50个赛事龙舟竞渡场的案例研究，对空间类型表征的4种滴网结构模式进行分析，并剖析其空间类型、竞渡规律和社会空间化特征；第四，对龙舟竞渡具体过程中的竞渡水域要素、竞渡陆域要素、装饰要素的空间化特征进行分析。第五，基于上述研究，对城市化背景下滴网结构的破网现象和再结构过程展开对比，提出当前龙舟竞渡场发展对公共水域涉水性的需求。研究结果表明，首先，龙舟竞渡场空间形态互动过程呈现滴网结构，即龙舟竞渡场所在聚落与以水系为基础连接的聚落之间以龙舟竞渡活动为形式进行社会关系实践的动态空间结构。其次，我国的龙舟竞渡场有1327处，呈“南盛北活”的总体规律，分为4种滴网结构模式，代表了4种社会空间化的形式。基于龙舟竞渡过程中的水陆互动特征，竞渡水陆要素发挥了不同作用。最后，在城市化中，滴网结构随着社会关系的变化，存在破网现象。滴网结构再结构过程中空间层面的首要需求是对公共水域涉水性和涉水权的完善。
Dragon boat racing is a famous traditional cultural activity in China, and it is also a sport that China actively promotes to be incorporated into the Summer Olympics. However, there has not yet been a systematic study on the spatial environment of dragon boat racing. It is common to use non-spatial concepts, such as ‘dragon boat racing,’ to describe the spatial environment in which the sport takes place. At the same time, with the development of urban and rural areas in China，the harmonious development of human-water relations has affected the use of public waters. This study was carried out against this background, aiming to define dragon boat venues and related concepts from a spatial perspective, and to theoretically construct and analyze the spatial form interaction mechanism of dragon boat venues in different dimensions.First of all, a clear definition of the dragon boat venue is a place for dragon boat racing with mass participation in contemporary urban or rural public spaces. A complete dragon boat venue includes racing water field and land field. Secondly, we use the relevant theories of social network analysis, cultural topology, and relational geography to incorporate the social interaction process of the water system as the basis of form into the spatial form generation mechanism of the dragon boat venue, and construct the drip-network pattern theory. On this basis, the study carries out analyses from five dimensions. First, it refines the different stages of the existing dragon boat venues with different drip-network patterns. Second, a database was established based on 6997 pieces of local chronicle information which revealed the distribution regularity of dragon boat venues, analyzed from the perspective of drip-network patterns. Thirdly, based on the case study of 190 intangible heritage dragon boat venues and 50 event dragon boat venues, the four drip-network patterns are used to characterize the space type. We analyze its pattern of spaces, racing rules and social spatialization; fourth, analyze the spatial characteristics of the water field elements, land field elements, and decorative elements in the specific process of dragon boat racing. Fifth, based on the above research, we compare the network breaking phenomenon and restructure process of the drip-network patterns under the background of urbanization, and the basic needs for the current development of dragon boat venues are proposed.The research shows that, first of all, the spatial morphological mechanism of the dragon boat racing venue exhibits a drip-network pattern, that is, the social network spatialization of different settlements in the form of dragon boat venues connected based on the water system. Secondly, there are 1,327 dragon boat venues in China, which follow the general pattern of “more in the south, less in the north”. They are divided into four drip-network patterns, representing four forms of social network spatialization. Based on the interactive characteristics of water and land during dragon boat racing, the water and land elements of the race play different roles. Finally, during urbanization, the network structure changes with social relations, and there is a disruption in the drip-network pattern, so a restructuring process is needed. Among them, the primary demand at the spatial level is to improve the urban wading ability of public spaces and wading rights of public water.
