国家生态屏障区1-km分辨率土壤保持逐年数据集（2000-2015）

土壤保持服务常用土壤保持量（Soil Conservation, SC）进行评估。作者运用MOD13A2 NDVI 、ASTER GDEM、气象站点及中国土壤数据集等数据，基于修正的通用土壤流失方程（Revised Universal Soil Loss Equation, RUSLE），研发了国家生态屏障区1-km分辨率土壤保持逐年数据集（2000-2015）。该数据集投影坐标系为WGS_1984_Albers，单位是 t km-2 a-1。数据存储为.tiff格式，由16个数据文件组成，数据量为0.99 GB（压缩为1个文件，数据量为168 MB）。与本数据集相关的科学发现论文发表在《地理研究》2019年第38卷第9期。

Soil conservation services are commonly evaluated using the Soil Conservation (SC) metric. The authors utilized multiple datasets including MOD13A2 NDVI, ASTER GDEM, meteorological station data, and the China Soil Dataset, and developed an annual 1-km resolution soil conservation dataset for the National Ecological Barrier Zone covering the period 2000–2015 based on the Revised Universal Soil Loss Equation (RUSLE). The coordinate reference system of this dataset is WGS_1984_Albers, with the unit of t km⁻² a⁻¹. The data are stored in TIFF format, comprising 16 individual files, with an uncompressed total size of 0.99 GB; when compressed into a single file, the size is 168 MB. The peer-reviewed scientific paper associated with this dataset was published in *Geographical Research*, Volume 38, Issue 9, 2019.
