Environmental Effects and Efficient Utilization Research Mode of Yantai Dagujia River Resources Development

摘要

Natural water cycle is of river-basin characteristic, with obvious river-basin regularity in formation, movement and change. The development and utilization of river-basin water resources are of important significance to solve the shortage of water resources. Dagujia river is the second largest river in Yantai. But with fast development of social economy and population growth of Yantai city, Dagujia river resources have been overexploited, resulting in corresponding environmental effects. Based on the thorough investigation of the current water resources utilization, the paper analyses the production and the change trend of environmental effects and discusses projects and management mode in order to achieve efficient utilization of water resources.
