According to the research achievements acquired through studying on combination of lightning prevention and insulation of transformer yard in large scale hydro projects such as Gezhouba project, it is derived that GIS (gas insulated switch gear) for 500 KV stations may be simply protected by a line lateral lightning arrestor and a bus line lightning arrestor.

Research on Balanced Optimization Analysis of Substation Project Management;

To reduce the ground resistance of large substations in areas with high soil resistivity is attracting much attention.

On the basis of introduction of concept as well as methods of measurement of ecological integrity,effect of construction of Shuangxi hydropower station project on regional ecological integrity is expounded in the paper in terms of three aspects: productivity of natural system,state of stability of natural system,and quality of landscape ecosystem.

Application of decision model of fuzzy multi-attribute to some program optimization of a certain hydropower project;

Research on Soil and Water Conservation Monitoring of Hydropower Project in Sichuan Province;

The work of time-limit control of a hydropower project should be run through the course from start to finish, it is the effective measure for saving investment and improving economic benefit of the project.

The purpose of the paper was to search for the models of land consolidation,effectively to increase the area of farmland,to improve land-use efficiency on the condition of menacing by big hydropower project.
