Effects of Water Level Changes on the Hydrological Connectivity and Water Quality of a Lake-Type Wetland
Provisionally accepted- Guilin University of Technology, Guilin, China
The impact of water level fluctuations on wetland ecosystems is crucial for water resource management and ecological conservation. While there have been some studies on this topic, comprehensive analyses of how water level changes affect the hydrological connectivity and water quality of lake-type wetlands remain relatively limited.This work aims to explore the impact of water level changes on the connectivity and water quality of lake-type wetland water bodies.Water quality data for Mudong Lake from January 2021 to December 2022 were obtained by collecting water samples and conducting laboratory tests. Additionally, through a combination of remote sensing image data, drone image data and actual measured data on the Mudong Lake water level, the comprehensive ecological-hydrological connectivity index and comprehensive water quality index were used to evaluate the water level changes in Mudong Lake,water body connectivity, and water quality. The correlations between them were then analysed.The results show that as the water level increases, the degree of landscape fragmentation decreases, and the water connectivity index increases by 262%. In addition, as the water level increases, the comprehensive water quality pollution index shows an overall downwards trend, but the factors affecting water quality are complex and changeable and require further in-depth research. This study provides an important reference and data support for understanding the impact of water level changes on lake ecosystems.
