Abstract

This paper aims to explore the implementation of the ecological restoration and water and soil loss control measures proposed in engineering design & research, environmental impact assessment report and approval document with respect to the construction and environmental management of a project case, and to put forward the remedial measures and suggestions for the existing problems. The application of remote sensing technology to the eco-environment monitoring in the pre-construction phase, construction phase and operation phase of Phase I Tao River Water Diversion Project was studied. It was obtained that all disturbed areas of this project already reached the levels before the construction by combining biological control measures and vegetation measures. The ecosystem structure, processes and functions in the project construction area did not exert any great impact. The ecological environment in the project area was fragile with poor quality, and could be easily deteriorated due to the disturbance of human activities. The changes in the area and pattern of ecosystem in the project area were influenced by this project to a very small extent. The quality of natural ecological environment before the construction was basically recovered through its ecological restoration measures, and the current ecological restoration benefit was favorable. Therefore, the remote sensing technology is capable of technically demonstrating whether a project meets the acceptance conditions for environmental protection upon completion and providing basis for the follow-up application of remote sensing technology in eco-environmental investigation.
