RETRACTED: Regional Eco-Environmental Information Service System Based on Open Source Projects (Retracted Article)

In arid area of western China, due to harsh natural conditions, ecosystems are less stable and easily affected by human activities. In recent decades, significant amount of research on the impact of human activity on environmental change in arid areas have been done. Though no particular conclusions were drawn, a number of eco-environmental data were accumulated. For lack of effective means of sharing, these data exit in form of "Information Island". To use the data more efficiently, a WebGIS prototype for regional eco-environment service system is constructed using open source software such as PostgreSQL, PostGIS, GeoServer, OpenLayers and etc. Implementation techniques, system function and key procedures were also described. This system, of high practical value, will be able to provide the public, scientists, and administration with convenient and rapid access to eco-environmental information.
