UNEARTHING DECADAL COASTAL TRENDS IN HEILONGJIANG AND SHANDONG WITH GOOGLE EARTH ENGINE

Abstract

Terrestrial water bodies, encompassing rivers, lakes, reservoirs, channels, and ponds, constitute vital sources for agricultural, industrial, and domestic water supply, alongside their pivotal role in modulating terrestrial hydrology and ecological equilibrium. The temporal and spatial fluctuations of these water bodies are subject to an array of influences, ranging from climatic determinants like annual mean temperature and precipitation levels, to anthropogenic elements including agricultural irrigation practices and the development of water conservation projects. The transformations within these water bodies pose substantial risks to regional agriculture, social stability, and the broader ecological milieu. Consequently, vigilantly monitoring the dynamic shifts in these water bodies assumes paramount importance in safeguarding ecological integrity and propelling sustainable progress within watersheds
