Abstract: Since the80s of the20th century,because of rapid industri al development ,the number of cities in China has been quickly increased from1 80to666;consequently the urban population and water demands have also rapi dly increased,thus causing severe shortages of water resources in urban areas .In-creasingly serious water pollution caused by urban development not only does great damage to human health but also intensifies their shortages.Variou s negative effects of groundwater over-exploitation such as land subsidence, karst collapse and seawater intrusion have become serious public hazards and c aused great economic loses.According to these problems ,the author analyzes d ifferent causes for urban water shortage and its eco-environmental influences in urban areas,and then proposes rational planning and reasonable u-tilizatio n of urban water resources,as well as effective measures for saving water and exploring new sources,protecting the eco-environment and preventing geologic al disasters.
