Abstract & Keywords
Abstract: The Beijing-Tianjin-Hebei Region enjoys an important geographical position in China. It is located in northeast Asia and at the heart of China’s Bohai Sea. Dynamic monitoring of vegetation coverage is of great significance for protecting and improving the ecological environment. In this paper, MOD13A1 data from 2000 to 2019 were downloaded, and MRT, ERDAS and ARCGIS software were used to obtain the vegetation coverage dataset in the Beijing-Tianjin-Hebei Region through band extraction, maximum synthesis method and pixel dichotomy model method. This dataset can be used to analyze the evolution of the spatial and temporal pattern of vegetation coverage in the Beijing-Tianjin-Hebei Region, the correlation between vegetation coverage and influencing factors, as well as the changes of ecological environment.
Keywords: Beijing-Tianjin-Hebei Region; fractional vegetation cover; MODIS
