摘要：Land cover change survey plays an important role in the sustainable development of the national economy. In view of the increasing amount of land change survey data, the service response time increases. At the same time, the size of data cannot satisfy scale of distributed GIS. According to the characteristics of the land change survey data, this paper studies the change survey data storage strategy based on Redis memory database, and puts forward a traditional server framework, use Redis as a buffer layer of the back-end service framework, and validated it. The results show that the data organization strategy based on Redis significantly improve the response speed of the back-end service, and has better ability to deal with concurrency, the use of a certain significance in the land change survey. Compared with several memory substitution strategies, LRU (Least Recently Used) can make the cache layer have higher cache hit ratio.
