摘要
低空作为城市空间的重要组成,是精细化城市空间管理的目标对象,通过空间坐标进行位置刻画,具备显著地理基因。随着城市低空应用的日益增多,以低空通行为代表形成的复杂空间利用情况已经突破传统空域,介入城市贴地表空间,影响城市建筑和人居环境权益,突显三维土地空间的役使问题。在城市的土地管理方面,宗地被用作管理城市土地空间的基本单元,承载权属关系及空间权益信息,宗地之间构建地役权可以确保权属方对他属空间的合法利用。由于贴地表的低空飞行活动已经进入城市土地空间的管理范围,厘清低空通行过程对宗地空间的利用和影响,构建城市低空通行役权是保障低空权益的迫切需求。常规地役权概念受限于土地平面认知约束,忽视立体空间的建模与表达,城市低空作为立体空间因低空通行活动而形成地役权关系时难以被清晰描述,如何实现低空通行役权的建模与表达成为关键。采用GIS技术对城市空间进行建模,实现物理世界到数字世界的特征刻画与映射是城市空间管理的重要信息化手段。本文以概念建模为目标,提出城市低空通行役权概念建模方法:通过剖析城市低空通行中飞行器运动条件、低空通行的人居权益影响、路径利用,来实现低空通行役权的约束性空间建模,作为概念模型的几何描述;以三维宗地的空间类型为基础,结合宗地内空间利用情况、飞行器起降模式和路径利用情况探讨宗地的供役条件,形成面向通行需求的宗地供役模式;抽取现有研究和法规中关于低空通行的概念,建立低空规划、价值和役权3个方面的语义关系,形成概念模型;最后,采用深圳市的低空物流案例进行实验论证,完成模型实例化与三维视图呈现。结果表明,围绕概念模型实现的“空间利用条件-数据建模-可视化表达”一体化方案能够清晰刻画城市低�
Low-altitude space is an important component of urban space.Requisite measures for precise and meticulous management of urban low-altitude are indispensable.The urban low-altitude space should be characterized by spatial coordinates and possess significant geographic attributes.With the increasing adoption of low-altitude applications in urban areas,the intricate utilization of space,represented by low-altitude traffic,has transcended conventional airspace boundaries and encroached upon near-ground urban space,exerting an impact on urban architecture and human settlement environment.Emphasizing the 3D land space's utilization and service,the issue of the utilization and management of 3D land space has become increasingly conspicuous.The land parcel serves as the fundamental unit for urban land management,recording information of ownership relationships,spatial rights,and interests information.The establishment of easements between land parcels ensures the lawful utilization of relevant spaces.Given the inclusion of low-altitude flight activities within the purview of urban land management,there is an urgent imperative to elucidate the spatial utilization and impact of low-altitude passage processes on land space while establishing the service rights of urban low-altitude passage to safeguard parcel interests.However,the concept of easement is limited by the cognitive constraints imposed by a 2D land plane,neglecting the modeling and representation of 3D space.Precisely articulating the easement relation ship for med by low-altitude passage activities in urban low-altitude space poses a significant challenge.Utilizing GIS technology for modeling urban spaces and facilitating the characterization and mapping from the physical to digital realms has consistently served as a crucial information tool in urban space management.Drawing upon the core principles of GIS modeling methodology and conceptual modeling,this paper presents a conceptual approach for describing low-altitude passage easement in urban areas.By analyz
