摘要
水是人类社会发展生产的基础资源。随着遥感技术与云计算技术的不断发展,谷歌地球引擎(Google Earth Engine,GEE)平台成为了大规模和长期的地表水体分析与制图的重要手段。采用Landsat 5TM和Landsat 8OLI卫星数据,分析了1985~2023年6月至9月的蒙古国地表水体的时空变化特征。研究结果表明,1985~2023年蒙古国地表水体的面积呈下降趋势,稳定水体面积从15547.71km2缩减至14452.13km^(2)。其中,大型水体保持相对稳定,主要是小型湖泊和河流发生变化。本文的分析结果为深入了解蒙古国的生态环境变化提供了重要的基础,并为准确预测蒙古国未来的水资源和环境变化以及水资源的有效管理和保护提供了方向。
Water is a basic resource for the development and production of human society.With the continuous development of remote sensing technology and cloud computing technology,the Google Earth Engine(GEE)platform has become an important means for large-scale and long-term surface water bodies analysis and mapping.Using Landsat 5 TM and Landsat 8 OLI satellite data,the spatial-temporal variation characteristics of surface water bodies in Mongolia from June to September 1985-2023 are analyzed.The results show that the area of surface water bodies in Mongolia showed a downward trend from 1985 to 2023,and the area of stable water bodies decreased from 15547.71 km^(2)to 14452.13 km^(2).Among them,large water bodies remained relatively stable,and small lakes and rivers changed mainly.The analysis results of this paper provide an important basis for an in-depth understanding of the ecological and environmental changes in Mongolia,and provide a direction for accurately predicting the future water resources and environmental changes in Mongolia and the effective management and protection of water resources.
