Abstract: The construction of the Giant Panda National Park is an important innovative and exploratory measure for the country to carry out ecological civilization construction. Taking the digital construction pilot of Tianquan area of the Giant Panda National Park as an example, this paper analyzes and discusses the construction of the intelligent park platform of the Giant Panda National Park based on the Internet of Things and 3D geographic information technology, gives full play to the advantages of IoT and GIS in dynamic monitoring and data visualization technology,and proposes the construction scheme of the intelligent monitoring system of the Giant Panda National Park based on IoT+GIS. The construction of the intelligent platform of the Giant Panda National Park is supported by geospatial database and thematic database, and integrates 3D GIS engine, BIM information model and IoT sensor data to realize the whole process, all-round and integrated real-time dynamic supervision of human activities, forest resources,wildlife resources, forest fire prevention and illegal poaching in the national park under 3D scenes.
