Abstract: The water conservancy informatization evolution promotes the rapid growth of water conservancy big data. And the actual production has proved the integration and sharing of the data can achieve the maximum benefit of them. But the existing storage platforms have a few deficiencies, such as unbalanced of storage capacity, and that can make these platforms be a hotspot. Based on the research of hybrid storage model, according to the exchange demand between the data centers and the storage capacity, we designed an adaptive distribution strategy based on spatial property of water conservancy data domain in which conducting the distribution decision. The experiment shows that this strategy can guarantee the basic load-balancing between data centers.
