Core Insights - The article discusses the recent snowfall in Jiuzhaigou, a UNESCO World Heritage site, and highlights the ongoing research on the physical characteristics and color formation of its lakes [3][4][5]. Research Objectives - The research aims to analyze the physical characteristics and causes of color variation in Jiuzhaigou's lakes, focusing on factors such as water depth, ecology, and light conditions [5][6]. - A significant goal is to explore the construction of a spectral index to quantify the contributions of various factors to the lakes' colors [5][6]. Methodology - The research incorporates multiple influencing factors, including physical, chemical, and biological aspects, to provide a comprehensive understanding of the lakes' color characteristics [6]. - The study utilizes advanced monitoring techniques and data collection methods, including drone-based hyperspectral imaging, to gather precise color data from key lakes [6][7]. Preliminary Findings - Initial results from the research have been obtained, and further data validation is expected before public release, promising a more detailed scientific analysis of the "Jiuzhaiblue" phenomenon [7].
