However, the construction of the Three Gorges Dam has seriously affected the wetland hydrology and landscape. Therefore, it is of great significance to study the landscape dynamics of Dongting Lake wetland and its response to hydrological changes. Based on GEE cloud platform, this paper will obtain the long-term landscape dynamic changes of Dongting Lake wetland and analyze the influence of changes of multi-period water conditions on wetland landscape. The results show that, 1) From 1985 to 2020, the typical vegetation area of Dongting Lake wetland changed obviously on the whole lake scale. The evolution of wetland landscape pattern mainly occurred in East Dongting Lake, west of South Dongting Lake and north of West Dongting Lake. 2) According to the M-K method, the water level data of Dongting Lake showed a sudden change in 2003. This led to the decline of the annual water level of Dongting Lake and the decline of the water level during the wet season and retreating season. 3) The main hydrological variables affecting the change of the area of </span><em>C. brevicuspis</em>(<em>Carex brevicuspis</em>) and <em>P. australis</em>(<em>Phragmites australis</em>) in Dongting Lake wetland are the mean water level and minimum water level in wet season, and the mean water level, the minimum water level and the maximum water level in retreating season.

The analysis of changes in the hydrographic network was based on a spatial comparison of hydrographic network elements on the basis of spatial sources. As a result of both natural and human-induced processes, there have been significant changes to elements of the hydrographic network of the BbNP. The length, area and sinuosity of the rivers in the BbNP area have decreased significantly in the XIX-XXI centuries, in contrast to the length of the canals dug in the XIX century - their length increased. On average, river channelization reduced channel water storage capacity by 49%. In other cases the average decrease of storage capacity of the channel was about 14%. As a result of drainage works in the XIX century, the network of drainage ditches was established in the BbNP, which was significantly extended (more than 6 times) in the XXI century.

A Penck-Oppokov method was used to assess the annual water balance, and runoff coefficient for 1951–2021. Data were extracted for the daily simulated dataset of Poland. The average annual water balance of the Biebrza basin encompassed of 561 mm of precipitation, 485 mm of evapotranspiration, 101 mm of runoff, and −25 mm of water retention. Analysis of 17 sub-basins indicated a declining tendency in water resources over the study period. The average runoff coefficient in the Biebrza basins is equal to 0.17. Findings presented here indicate that the significant deficit in the water balance in the region is highly unlikely to be compensated by the course of natural hydrological processes. This reveals the need for quick actions oriented at improvement of water balance by reducing the runoff and evapotranspiration.
