1980-2020年福州市30米LULC分类数据集（第一版）

该数据集为福建省福州市1980-2020年的土地利用/土地覆盖数据，含9个子数据。数据均通过Google earth engine平台中的支持向量机分类器生产，在生产过程中，所有的流程都被严格地监督和执行，比如高质量影像数据合成、样本点筛选、精度评价等 。数据的平均总体精度大于85%，具有一定可靠性。数据可为后续的土地利用/土地覆盖变化研究提供基础；同时，可为福州市的土地资源管理、自然资源调查以及环境监测等提供数据基础。

This dataset comprises land use/land cover data for Fuzhou City, Fujian Province spanning from 1980 to 2020, including 9 sub-datasets. All data were generated using the Support Vector Machine classifier on the Google Earth Engine platform. Throughout the entire data production workflow, strict supervision and standardized implementation were enforced, covering steps such as high-quality remote sensing image synthesis, sample point screening, and accuracy assessment. The average overall accuracy of the dataset exceeds 85%, indicating substantial reliability. This dataset can serve as a fundamental data basis for subsequent land use/land cover change research, as well as provide data support for land resource management, natural resource investigation, and environmental monitoring efforts in Fuzhou City.
