Some problems in environmental protection appears in construction of power grid, such as the increasing environmental protection pressure in power grid corridor planning, ignorance of environmental assessment in power grid planning, poor environmental protection work in power grid design, and the environmental protection and water-soil conservation measures unfulfilled in design of the main project, which has impeded the power grid construction to various degrees. An analysis is made on above problems and their causes, and some countermeasures are also proposed such as dedicated power grid environmental protection design, developed environmental protection and water-soil conservation design for power engineering, and establishment of environmental protection and water-soil conservation design review mechanism and others.
