祁连山区域30m人类活动参数产品数据集（V3.0，2021）

本数据集为2021年的祁连山区域的人类活动参数，包括祁连山区域2021年的30m耕地产品和祁连山区域2021年的30m建设用地分布产品。该产品来源于祁连山区域2021年30m的土地覆盖分类产品。该产品以2020年的土地覆盖分类产品为基础，基于Google Earth Engine平台的Landsat系列数据和强大地数据处理能力，利用变化检测的思想和方法生产得到，总体精度优于85%。该产品是1985-2020年土地覆盖分类产品的延续。1985-2020年的土地覆盖分类产品也可在本网站下载得到。其中，1985-2015年的土地利用产品为5年1期，2015-2021年的土地利用产品为1年1期。

This dataset provides human activity parameters for the Qilian Mountains region in 2021, including the 30-meter resolution cropland product and 30-meter resolution built-up land distribution product of the region in 2021. These two products are derived from the 30-meter resolution land cover classification product of the Qilian Mountains region in 2021. The 2021 land cover classification product was developed based on the 2020 land cover classification product, leveraging Landsat series data and robust data processing capabilities on the Google Earth Engine platform via change detection theories and methods, with an overall accuracy exceeding 85%. It is a continuation of the land cover classification products from 1985 to 2020. The land cover classification products covering 1985 to 2020 are also available for download on this website. Among these products, the land use products from 1985 to 2015 are released at 5-year intervals, while those from 2015 to 2021 are updated annually.
