CCropland30: High-resolution hybrid cropland maps of China

China’s high-resolution hybrid cropland maps (CCropLand30) by integrating state-of-the-art remote sensing LULC products (GlobeLand30, GLAD, CLUD, CLCD, and CACD) with the recently released county-level cropland area data from the latest national land survey (NLDS). CCropLand30 has a higher pixel-scale accuracy than the input maps, and exhibit better spatial agreement with the NLDS data. The dataset can provide great support for cropland monitoring, management, and various research fields such as water resources, agriculture, and climate change. Five hydbrid maps circa the years 2000, 2005, 2010, 2015, and 2020, were provided in the dataset.

本数据集为中国高分辨率混合耕地图谱（CCropLand30），通过融合当前先进的遥感土地利用与土地覆盖（Land Use/Land Cover，简称LULC）产品（包括GlobeLand30、GLAD、CLUD、CLCD及CACD），与最新发布的基于全国土地调查（National Land Survey，简称NLDS）的县级耕地面积数据构建而成。CCropLand30的像素级精度优于输入的各类遥感产品，且与NLDS数据的空间匹配度更高。该数据集可为耕地监测、管理以及水资源、农业、气候变化等多个研究领域提供有力支撑。本数据集包含2000年、2005年、2010年、2015年及2020年共5幅混合耕地图谱。
