城市化进程中的地籍数据清理与问题分析

Cadastral Data Clearing and Problems Analysis in Urbanization Process

针对在快速城市化进程中,土地的利用类型和相应的地籍信息变更频繁,地籍数据常存在缺失、不全、错误、冗余等问题,以深圳市龙岗区大运新城为研究区,通过地籍数据清理分析城市化过程中地籍数据存在的主要问题,发现数据更新不及时是导致地籍数据问题的主要因素;此外,非农建设用地入市、不同系统数据的不一致性和人为错误也是导致地籍数据问题的重要因素。城市化进程中,为了避免出现大量的地籍数据问题,需要完善地籍数据的共享和动态更新机制,加强数据的质量控制。

In rapid urbanization process, land use and corresponding cadastral information vary frequently. Cadastral data usually has problems such as missing,incompleteness, error and redundancy. In this paper, Dayun new town of Longgang district,Shenzhen city was chosen as a study area. A cadastral data clearing project was implemented in the study area. Then cadastral data problems were analyzed in the use of the project results. It is found that delay of data updating is the main cause of cadastral data problems. Besides,entering market of non-agricultural construction land,data inconsistency among different systems and human errors are also important causes of cadastral data problems. In order to avoid vast cadastral data problems in urbanization process,the sharing and dynamic updating mechanism of cadastral data should be improved,and the quality control of cadastral data should be strengthened.
