黄土高原500m分辨率逐月分式植被盖度数据集(2001-2018年)

该数据集为黄土高原分式植被盖度数据，空间分辨率为500m，时间为2001.01-2018.03。数据格式为tiff。该数据集从2001-2018年MODIS产品（MCD43A4，MOD09A1）中衍生，将每个像元分为光合植被（photosynthetic vegetation，PV）、非光和植被（non-PV，NPV）、裸土（bare soil，BS）三个组分，经处理后得到逐月的FVC产品（PV、NPV、BS），通过预处理填补了空值区域，并通过空间掩膜纠正了异常值地区（水体、雪、城市），然后利用计算公式计算土壤侵蚀植被覆盖因子（CFACTOR）。

This dataset refers to fractional vegetation cover (FVC) data for the Loess Plateau, with a spatial resolution of 500 m and temporal coverage from January 2001 to March 2018. The data is stored in TIFF format. Derived from MODIS products (MCD43A4, MOD09A1) during 2001–2018, each pixel in this dataset is partitioned into three components: photosynthetic vegetation (PV), non-photosynthetic vegetation (NPV), and bare soil (BS). Monthly FVC products (PV, NPV, BS) are obtained through post-processing. Missing value regions are filled via preprocessing, and outlier areas including water bodies, snow cover and urban regions are corrected using spatial masking. Finally, the vegetation cover factor for soil erosion (C-factor) is calculated with a predefined computational formula.
