The invention relates to a wet land ecological event acquisition and early warning method and system, wherein the system consists of two parts, namely an event collecting system and an event early warning system. The event collecting system comprises an image collector, a GPS (Global Positioning System) module, an event editing module, a communication module, an event memory, a map module and an event processing module; and the event early warning system comprises a receiving module, an interpretation module, a reviewing and issuing module, a decision analysis module, a map display module, an event business database and a geo-spatial database. The event collecting system and the event early warning system are communicated with each other through a short message center platform and wireless transmission. In the invention, the wet land ecological event acquisition and early warning method and system are convenient, efficient, real-time and dynamic, and can be used for monitoring and managing wetlands and ecological environment, thereby changing the condition that an ecological event is delayed to find, hard to collect, and slow in processing and not available to the public in the wetland protection.
