Abstract: According to field investigation and various collected information and data. I systematically analysed a series of delta environmental variations in the Luanhe River Delta after the water conservancy projects were built in the Luanhe River Basin. Since 1980, great changes of the river hydrology have taken place at the lower reaches of the Luanhe River. The runoff, sediment yield and water discharge decreased obviousiy. They caused delta environmental variations, such as coastal erosion, decline of ground water table, salty water intrusion, soil salinization, river bed erosion, deposition in the river courses in the estuary, and so on. I also tried to predict the evolution of the delta environment and put forward some proposals to control the environmental variations in the Luanhe River Delta. 

Key words: the water conservancy projects in the Luanhe River Basin, the Luanhe river hydrology, Luanhe River Delta
