摘要:丹江口水库作为南水北调中线工程水源,利用遥感影像对水库边界进行长时间序列动态变化监测,对于保障南水北调调水量具有重要意义。本研究采用多时相Landsat遥感影像集,通过修正的归一化差异水指数(mNDWI)、增强植被指数(EVI)和归一化差异植被指数(NDVI)之间的关系,基于Google Earth Engine云平台获取了长时间序列的丹江口水库地表水体空间数据集。本数据集包括了2000–2020年21期丹江口水库水体空间数据,可以为研究丹江口水库水体时空变化提供依据,也可以作为研究该区域气候变化、生态环境变化的基础数据。

Abstract & Keywords
Abstract: The Danjiangkou Reservoir is the water source of the South-to-North Water Diversion Project. The use of remote sensing images to monitor the long-term changes of surface water for the reservoir is of great significance for ensuring the water transfer volume of the South-to-North Water Diversion. In this study, multi-temporal Landsat remote sensing image was used to obtain a long-time series of spatial surface water dataset for the Danjiangkou Reservoir (Henan province) based on Google Earth engine cloud platform through the relationship among modified Normalized Difference Water Index (mNDWI), Enhanced Vegetation Index (EVI) and Normalized Difference Vegetation Index (NDVI). This dataset includes the 21-years spatial surface water dataset of Danjiangkou Reservoir from 2000 to 2020, which can provide a basis for studying Danjiangkou Reservoir's surface water temporal and spatial changes. The dataset can be used as basic data for the study of climate change and ecological environment changes in the region too.
Keywords: Danjiangkou Reservoir;  water body boundary; Google Earth Engine; water source area change
