Combined with the current general situation of ecological environment protection and actual demand of ecological environment monitoring and management, this paper discussed the “14th five-year plan” development ideas of ecological environment three-dimensional remote sensing monitoring. To better guide the three-dimensional remote sensing monitoring work for ecological environment in the current and future, we put forward the view of building the three-dimensional remote sensing monitoring network for ecological environment integrating sky, space and earth, establishing three-dimensional remote sensing monitoring system and index system for ecological environment, and implementing three major projects for three-dimensional remote sensing monitoring of ecological environment.
