Ecological problem has become one of the major problems faced by mankind in the twenty-first Century, and the collection, storage, management and utilization of ecological environment information, is to solve the problem of ecological environment on human. Study of ecological environment involves a large number of spatial data, but due to the ecological environment of the cycle is long, range is wide, the variety of data, coupled with the ecological environment itself to the diversity and complexity, will cause the formation of ecological environmental data space, structure and semantic difference. Therefore, using GIS technology to establish the ecological environment information system, for the ecological environment information effective management and reasonable use, accelerate the ecological environment problems in informatization process be imperative.
