2026-09-18 Soil Nutrient Remote Sensing Monitoring Dataset of the Core Demonstration Area in Lishu County, Jilin Province (2021) doi:10.57760/sciencedb.iga.01077 en Soil Nutrient Remote Sensing Monitoring Dataset of the Core Demonstration Area in Lishu County, Jilin Province (2021) focuses on the core demonstration area of ​​black soil protection in Lishu County, Siping City, Jilin Province. Its aim is to provide high spatial resolution soil nutrient information to support regional farmland quality assessment and precision agricultural management. Based on Zhuhai-1 hyperspectral satellite imagery acquired in 2021, combined with ground-measured soil sample data, a soil nutrient inversion model was constructed. The overall inversion accuracy of the model is better than 80%. Spatial inversion and mapping of surface soil nutrient content in the study area were then performed. The dataset includes two key soil nutrient indicators: total nitrogen and total potassium. The dataset results mainly include remote sensing thematic maps of soil nutrients and their inversion results. The inversion results are stored in GeoTIFF (*.tif) raster format with a spatial resolution of 10 m, effectively depicting the spatial distribution characteristics of soil nutrients within the core demonstration area. This dataset can provide fundamental data support for farmland quality monitoring, black soil protection and utilization assessment, and precision agricultural management. remote sensing monitoring; soil total nitrogen; soil total potassium 张霞 肖青 PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
