Abstract: Ecological deterioration is becoming a significant factor restricting China's economic development. In the protection and construction of ecological environment, strengthening the establishment of ecological monitoring network and effectively monitoring the environmental changes are the basic works. An integrated "space-ground" monitoring network frame for soil and water conservation of construction projects is put forward. This paper emphasizes technologies such as the combination of high altitude, medium-altitude and lower-altitude remote sensing images, construction of monitoring automation, space-ground communication and data transmission, supplements relevant standards and network assurance systems, and also points out the developing direction of the "space-ground integration" monitoring on soil and water conservation.
