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.
Highlights
Based on the Tao diversion project is a livelihood project to solve the arid area of central Gansu and realize the sustainable development of the ecological environment of the Tao River, the application of remote sensing technology in the Tao diversion project is very necessary

Jiudianxia hydro-junction project taken as the water source, Gansu Tao River Water Diversion Project focuses on solving domestic and industrial water, rural human and animal drinking water and water of ecological environment in six key cities, counties and towns enjoying national poverty alleviation policies in central region of Gansu Province, including Dingxi and Longxi, appropriately developing local water-saving irrigation agriculture, improving domestic water and industrial and agricultural production conditions, and providing water resource guarantee for the regional economic and social development and construction of a moderately prosperous society
Summary
Of main urban water bodies in the field of environmental protection, expounded the principles and methods and satellite data extraction during the water body monitoring via the remote sensing technology, so as to reach the goal of real-time environment monitoring. Zhao P Z [9] conducted the data modeling and analysis using the data visualization This method could be used to rapidly master the actual status of water body and effectively treat it, which could greatly improve the working efficiency and provide a more innovative solution to the present water environmental treatment. Chen R [13] implemented a technical analysis of the specific applications of ion chromatography by combining its features and strengths, in an effort to enhance the concrete effect in water environment monitoring and improve the development level of environmental protection cause. The remote sensing technology should be applied to this project and better serve the environment monitoring and protection work in this project, providing an important method and basis for the environment monitoring upon the project completion
