青藏高原黄河源区植被覆盖度空间分布图（2015）

本数据集为青藏高原黄河源区2015年逐像素年内最大植被覆盖度空间分布图，该区域的面积约为4.4万平方公里。此数据是基于2015年MODIS（空间分辨率250米） 和Landsat-8 OLI（空间分辨率30米）植被生长季（5月初-9月末）的时间序列影像，并利用最大值合成方法、像元二分模型和时间插值等方式获得。植被覆盖度空间分布图的空间分辨率为30米，采用WGS 1984 UTM 投影，数据格式为grid格式。

This dataset is a per-pixel annual maximum vegetation coverage spatial distribution map for the source region of the Yellow River on the Qinghai-Tibet Plateau in 2015, with a total area of approximately 44,000 square kilometers. This dataset was derived from time-series remote sensing images of the 2015 MODIS (spatial resolution: 250 m) and Landsat-8 OLI (spatial resolution: 30 m) acquired during the vegetation growing season (early May to late September), using methods including maximum value composite, dimidiate pixel model, and temporal interpolation. The vegetation coverage spatial distribution map has a spatial resolution of 30 m, adopts the WGS 1984 UTM projection, and is stored in grid format.
