摘要

The impact of 500 kV transmission lines of Anqing power plant across the lake wetland reserve along the Yangtze River on the safety of the ecosystem was taken as the researched object. The power frequency electric field intensity (PFEFI), power frequency magnetic field intensity(PFMFI), radio interference, construction noise, vegetation destruction and the influence on water quality were investigated and monitored, and the influences of PFEFI, PFMFI, radio interference and construction noise on wild animals, especially the habitats and migration of birds were mainly researched.The direct and indirect influences on the surrounding environment as well as plants and animals in sensitive areas were analyzed and predicted.The results firstly showed there existed a 182 400 m3 stereo-space ( PFEFI> 4kV/m) which made flying birds unsafe under the lowest height 11 m of the lines, which fills the gap in the research of this field. Finally, some operational protection countermeasures were put forward at the current technical level to achieve the win-win goal of economic development and natural protection.
