摘要:
作者基于Google Earth Engine平台,综合Sentinel-2光学影像、Sentinel-1合成孔径雷达影像、数字高程数据和参考样本,构建光学物候、雷达后向散射和地形特征,采用随机森林算法形成南疆核桃与红枣种植10-m栅格数据集(2025)。2025年参考样本共21,576个,其中15,101个用于模型训练,6,475个用于独立验证;七类验证总体精度为90.76%,Kappa系数为0.8902,合并后的四类产品总体精度为92.97%,Kappa系数为0.8953。根据最终分类栅格有效像元统计,核桃面积为417,889.25 ha,红枣面积为311,428.37 ha。数据集内容包括:(1)核桃与红枣种植空间分布数据(10 m分辨率)及说明;(2)核桃与红枣等的种植面积与分类精度统计数据。数据集存储为.tif、.txt和.xlsx文件,由4个文件组成,数据量为625 MB(压缩为1个文件121 MB)。
