Abstract

Traditional management systems for environmental conservation usually have defects such as backward data management mode, lack of multi-source dynamic association, and unsatisfactory visual effect. With digital control of environmental conservation for river basins as the target, we put forward the design idea of digital environmental management platform for river basin by systemically analysing problems we face. The fusion management and dynamic linking of data were realized through data classification storage, multi-source data cleaning and unified data encoding. On this basis, functions of the digital management of environmental conservation can be met by integrating Internet of Things (IOT) data collection, numerical simulation model and statistical analysis algorithm. Hence, environmental conservation of the basin can be displayed in three dimensions based on three-dimensional Geo-information System(3D-GIS) and Building Information Modeling (BIM) fusion technologies. The management platform was applied to the Yalong River Basin, and especially to the realtime monitoring and 3D query of data and operation scenes in the water intake facilities of Jinping-I hydropower station. The platform improved the operation efficiency of the water intake facilities and reduced the eco-environmental risks for the basin.
