A wetland is a natural complex formed by the combined processes of land and water. Owing to its rich biodiversity, high productivity, and unique ecological function, wetlands are referred to as "the kidneys of Earth." However, under the dual effects of increasing anthropogenic activities and climate change, this important ecosystem is under significant pressure, such that wetland areas are becoming severely fragmented, gradually shrinking, and are generally on the decline. This study used the Google Earth Engine (GEE) platform to determine changes in land cover and surface water distribution in the Momoge National Nature Reserve (MNNR, western Jilin Province, China) from 1984 to 2018. In the past 30 years, wetland area is gradually replaced by farmland. Under the combined effect of anthropogenic and natural factors, there is a major decrease in the amount of surface water in MNNR. The surface water of 352 km(2) has been reduced by 10% in the past 30 years, and of which only 11.6% is permanent water. As seasonal surface water accounts for 40% of the total water bodies, this decline has resulted in a relative degradation of the wetland system, a decrease in hydrological connectivity, and an increasing trend of wetland fragmentation.
