摘要
利用近24年来不同时期的Landsat-8 OLI_TIRS卫星遥感图像作为数据源,本文对武汉市东湖水域进行了研究,分析得出近年来东湖水域面积动态变化情况,运用改进的归一化差异水体指数法(MNDWI)对水域面积进行提取,并结合历年各项气象数据、城市发展数据等影响因子进行相关性分析,研究结果表明:东湖近年水域面积变化与城市发展改造和人类利用方式变化具有很大相关性。
In this paper,the Landsat 8 OLI_TIRS satellite remote sensing images of different periods in the past 24 years are used as data sources to study the water area of the East Lake in Wuhan.The dynamic changes of the water area of the East Lake in recent years are analyzed.The water area is extracted by the improved normalized difference water index(MNDWI),and the meteorological data and urban development data of the past years are combined.The results show that the change of water area of East Lake in recent years is closely related to the change of urban development and human utilization.
