The wetland ecological environment monitoring system comprises a plurality of NB-IoT terminal nodes, an NB-IoT base station, an NB-IoT cloud platform and a monitoring terminal. The NB-IoT base station receives the monitoring data of the NB-IoT terminal nodes and then forwards the monitoring data to the NB-IoT cloud platform. The monitoring terminal realizes remote monitoring and control through the NB-IoT cloud platform. Each NB-IoT terminal node comprises an acquisition module, a communication module and a control module which are connected in sequence, wherein the acquisition module is used for acquiring the monitoring data, the control module is used for receiving and processing the monitoring data, and the communication module is used for acquiring the monitoring data processed by the control module and sending the monitoring data to the NB-IoT base station. According to the wetland ecological environment monitoring system based on the NB-IoT, the wide coverage characteristic of an NB-IoT network is utilized, a sensor data first-level network access framework is built through the NB-IoT terminal nodes, and the system failure rate can be reduced.
