| 由于传统系统在地质灾害数据信息化管理中应用效果不佳，不仅数据冗余度比较高，而且误码率也比较高，无法达到预期的信息化管理效果，为此提出基于GIS的地质灾害数据信息化管理系统设计。在系统硬件方面对GIS设备、转换器选型与设计，利用GIS设备采集地质灾害区域空间地理信息，利用转换器将模拟量数据转换为数字量数据；在系统软件方面，利用哈希算法对重复数据识别、删除，并通过对地质灾害数据缩放处理，降低数据维度，利用数据库技术对地质灾害数据标准化存储管理，以此实现基于GIS的地质灾害数据信息化管理系统设计。经实验证明，设计系统数据冗余度在01以内，误码率低于3%，在地质灾害数据信息化管理方面具有良好的应用前景。 |

| Due to the poor application effect of traditional systems in the information management of geological disaster data，not only is the data redundancy relatively high，but also the error rate is relatively high，which cannot achieve the expected information management effectTherefore，a GIS based geological disaster data information management system design is proposedIn terms of system hardware，select and design GIS equipment and converters，collect spatial geographic information of geological disaster areas using GIS equipment，and convert analog data into digital data using converters；In terms of system software，hash algorithms are used to identify and delete duplicate data，and geological disaster data is scaled and processed to reduce data dimensionsDatabase technology is used to standardize storage and management of geological disaster data，thus achieving the design of a GIS based geological disaster data information management systemThrough experiments，it has been proven that the data redundancy of the design system is within 01，and the error rate is less than 3%It has good application prospects in the information management of geological disaster data |
