城市空间信息系统动力学演化机理与应用

Application of urban spatial information system dynamics evolvement mechanism

根据系统动力学理论和方法,构建了城市空间系统动力学过程模型,揭示了空间结构--空间认知--空间行为--空间过程--空间结构的演化过程。提出城市空间数据在时间、空间和过程上分为不同的层次,具有时态特性。构建了城市空间信息系统动力学过程模型,进而得出城市空间信息系统动力学演化机理。在此基础上,构建了空间信息基础框架数据库动态稳定模式,实现了数据库的动态稳定性。同时保证了各部门共同建设和分享一个框架数据库,避免了每隔几年就需要大规模修测城市地形数据库。新的工作流模式的应用,改变了传统粗放式的管理模式。

According to system dynamics（SD）, structure the system dynamics course model of urban space, have announced the space structure--Space cognition-Space behavior-Space course-Evolution course of the space structure. Put forward the urban spatial data to divide for different levels on time, space and course, have time characteristics. Structure the model for system dynamics course of urban spatial information, and then draw information system dynamics of urban space and evolve mechanism. On this basis, structure the mode for keeping system dynamic stability of the basic framework database of spatial information. Simultaneity guaranteed every department co-builds and shares a frame database, prevented examine city topographical database to build on a large scale to need every several years from. Have already guaranteed every department and shares a frame database. Application of the new mode, has changed the management mode of the traditional extensive type.
