Research on Information Database Construction in Alpine Wetland Environment

The importance of wetland protection is becoming more and more obvious. In order to make scientific decisions on wetland protection and grasp the changes of wetland in time, the environmental information database and environmental information system of Ruoergai alpine wetland are established to provide new technical methods and management schemes for wetland research and realize the automation of wetland environmental information management. In this paper, the alpine wetland as the research object, conceptual design, logic design and physical design process design, to build the framework structure of environmental information database. Based on remote sensing data, digital elevation data, environmental basic data and social and economic data, wetland environmental information database was constructed. This paper studies the model of geographic entity data, coding scheme, organization reconstruction and so on, and proposes the construction of geographic entity-oriented basic geographic information database and the establishment of geographic entity-oriented basic geographic information database including multi-temporal, multi-scale and multi-category. Through the self-driven updating technology of geographic entity-oriented database, it helps realize the multi-temporal basic geographic information data state geographic entity retrieval and updating can fundamentally solve the problems of repeated database updating and inconsistent current status.
