The invention belongs to the technical field of environment monitoring, and discloses an 
ecological environment monitoring gridding 
system based on 
big data architecture and a monitoring method thereof. The 
system comprises a ZigBee communication module, a 5G 
signal communication module, an environment information detection module, an information collection module, a state indication module, a 
cloud server module, an environment state evaluation module, an early warning module and a man-
machine interaction module. According to the invention, synchronous monitoring can be carried out on environmental information of multiple different positions at the same time, unified coordination management is facilitated, the environmental problem disposal efficiency is improved, data storage is carriedout through the 
cloud server, the data storage capacity and storage stability are improved, historical data can be conveniently checked, and data 
change analysis can be conveniently carried out; the data can be effectively simplified by performing preliminary screening 
processing on the collected data, the 
data transmission burden is reduced, and the transmission efficiency and the subsequent 
processing efficiency are improved, so that the response speed of the 
system is improved.
