| Abstract: | Environmental early-warning is extremely important for prediction of the environmental condition in future and its impact on sustainable development of a region. For this reason a early-warning information system is indispensable. In our study, an information system for early-warning of oasis eco-environment was designed. The system is an advanced tool which can be used for evaluation, early-warning and dynamic monitoring of eco-environment in oasis regions. The design of the system followed some principles, such as practicability, advancement, transplantation, extendability and so on. Its major function is to provide the information of sustainable development of oasis regions for decision makers. In this paper, the design technologies of both structure and functions of the system were presented, which includes the designs of the system's network topology structure, the overall logistic structure, as well as the designs of its functions and safety. The system is composed of four subsystems, i.e. the basic data subsystem, the data inquiry subsystem, the eco-environmental evaluation and early-warning subsystem, and the data output subsystem. The system provides possibility to eco-environment protection and regional sustainable development in oasis regions. |
