Considering the special location andenvironmental status of the contiguous region, advices are proposed in the paper: perfecting trans-regional managementssystem of water environment incorporating basin management agencies in local government activities; strengthening cooperation of two agencies: water conservancy agency and environment protection agency; enhancing integrated control ofwater pollution and flood-drought disasters; taking the interests of the whole river into acount and paying attention to bothstorage and drainage; broadening sources of water supply and inceasing water delivery; controlling pollutant discharge,developing water saving production system.展开更多

It has been one of the most destructive earthquakes since the founding of P. R. China in 1949. The quake caused not only tremendous loss of life and wealth, but also severe damage to transmission and substation facilities. After the disaster, an expert group from China Electric Power Research Institute (CEPRI) was sent for on-site investigation. This paper is a summary of the investigation, in which suggestions for electric equipment to resist earthquake disasters are also proponed.展开更多
