武汉市南湖2000-2021年水域面积时空变化分析
Analysis of Spatiotemporal Changes in Water Area of South Lake from 2000 to 2021 in Wuhan City
摘要
Abstract
Based on Landsat satellite data,the band ratio method was used to obtain the water area of South Lake in Wuhan City from 2000 to 2021,and the spatiotemporal changes of the water area of South Lake were analyzed.The results showed that in 2003,South Lake had its largest water area,with a decrease in water area during 2000-2007,an increase during 2008-2012,and another decrease during 2013-2021.The tim-ing of South Lake's management coincides with the period of increased water area,indicating the effectiveness of lake management.Overall,the water area of South Lake decreased from 2000 to 2021,with a total reduction of 1.02 km2.The most significant reductions occurred on the northern and eastern sides,and there was a rapid and abrupt decrease in South Lake's area during 2004-2005.South Lake's water area chan-ges exhibit a positive correlation with evaporation,and a negative correlation with temperature.Both the exponential smoothing model and the long short-term memory(LSTM)neural network model could predict South Lake's surface area.The water area was projected to increase from 2022 to 2024.However,the predictions from the exponential smoothing model were more accurate.关键词
