中国湖泊有机碳浓度和总储量数据集（1984-2023年）

数据集包含了1984-2023年中国24,366个面积0.01km2以上湖泊的有机碳DOC和POC浓度和储量。利用2004-2023年期间的大量的野外调查数据以及卫星遥感监测技术，研制通过卫星遥感反射率等数据估算湖泊有机碳DOC（溶解性有机碳）和POC（颗粒性有机碳）浓度和储量。
数据集包含4个excel表格文件，1.DOC conc. during 1984-2023.xlsx, 2.POC conc. during 1984-2023.xlsx, 3.DOC storage during 1984-2023.xlsx, 4.POC storage during 1984-2023.xlsx。

This dataset contains the concentrations and stocks of dissolved organic carbon (DOC) and particulate organic carbon (POC) for 24,366 lakes in China with an area larger than 0.01 km² from 1984 to 2023. Leveraging extensive field survey data collected between 2004 and 2023 and satellite remote sensing monitoring technologies, we developed a methodology to estimate the concentrations and stocks of lake DOC and POC using satellite remote sensing reflectance and other relevant data. The dataset includes 4 Excel spreadsheet files:
1. DOC conc. during 1984-2023.xlsx
2. POC conc. during 1984-2023.xlsx
3. DOC storage during 1984-2023.xlsx
4. POC storage during 1984-2023.xlsx

背景与挑战

背景概述

该数据集提供了1984年至2023年中国24,366个面积大于0.01平方公里的湖泊的溶解性有机碳（DOC）和颗粒性有机碳（POC）浓度与总储量信息，基于野外调查和卫星遥感技术，通过机器学习模型估算得出。其特点是覆盖时间长、湖泊数量多，并首次揭示了中国湖泊有机碳储量显著增加的趋势，挑战了以往研究假设，具有重要的科学价值。
