Analysis of Spatio-temporal Change Characteristics of Water Environment in Nansi Lake Based on Satellite Remote Sensing Monitoring

Abstract

Lakes play a crucial role in the preservation and distribution of surface water resources, making them integral components of environmental protection. This study utilizes remote sensing data obtained from Landsat-8 to investigate the temporal changes in water area, land use patterns, and distribution of cyanobacteria in Nansi Lake between 2015 and 2023. Furthermore, it conducts an extensive analysis of the environmental condition of Nansi Lake, considering the escalating environmental crises resulting from industrial and agricultural development in recent decades. By adopting a multidimensional approach, this article offers a comprehensive examination of the environmental situation in the Nansi Lake region. Notably, the findings of this study exhibit enhanced accuracy and practicality when compared to conventional environmental analysis methods. Consequently, this research contributes novel ideas and methodologies for the monitoring and safeguarding of the ecological environment of lakes through the application of remote sensing techniques.
