Impact of Land Cover Changing on Wetland Surface Temperature Based on Multitemporal Remote Sensing Data

Abstract

Changes in land use and land cover (LULC) have been studied in recent years. Urban/rural planning, temperature analysis, and environmental monitoring can benefit from examining these variations. Land surface temperature (LST) has a great potential to act as a global indicator of the status of wetlands and changes in their hydrological and evapotranspiration regimes, which are often linked to land use and cover changes. Using remote sensing data, several studies have examined LULC changes on LST. This multi-temporal analysis used images from Landsat during 2005 to 2020. This study compares surface biophysical properties to sub-pixel heat changes. This result shows that LULC classes have different LST. Expansion of Oil Palm plantations decreases LST, while bare land and impervious surface increases it. The LST declined 3ºC (0.115ºC each year) over 20 years in the research area. This research provides information demonstrating how plantation growth from deforestation raises the surface temperature. Meanwhile, plantation from shrub and bareland decrease the surface temperature. The development of LST trend maps and time series charts on an operational basis give wetland managers with a fast and dependable single indicator of the effect of land processes on water and energy flows, allowing them to better managing their wetlands. Continuous monitoring of LULC dynamics is needed to design sustainable land use regulations for environmental preservation and regional economic development
