The proposal of coordinated development strategy of Beijing,Tianjin and Hebei,and the development of the coastal areas of Hebei Province promoted the development of economic circle around the Bohai sea.The Cangzhou Bohai new district locates in the heart of Bohai economic circle, with the accelerating process of urbanization in the new district, the demand for water resources increases,which aggravated the shortage of water resources.This paper calculated the water supply and demand of Cangzhou Bohai new district with meteorology, water and planning data .The results showed the water demand of the new district is about 403 million m3 per year while the water supply is expected to be approximately 327 million m3 per year, and the water gap is nearly 760 billion m3 per year.By means of remote sensing interpretation, this paper estimated that the sea ice resources exploitation in the new district is expected to be approximately 176 million m3 per year, it can provide water of about 880 billion m3 per year.So the sea ice reserve is enormous. The cost of desalination of sea ice is low, and the water quality is good which can replace part of ecological and industrial water to reduce disaster losses of the new district.The reserve can also alleviate the shortage of water resources and provide reference for the other coastal areas which suffer from sea ice disaster.
