Paper Abstract

In the upper stream of Yellow River, the status of vegetation cover is not as good as other location in the east of China. Considering the huge economic benefit of building hydroelectric stations, people took a lot of measures to structure hydropower stations, including in the upper stream of Yellow River. The objective of this study was to figure out the temporal variation and spatial rules of the vegetation cover based the time-series Moderate Resolution Imaging Spectroradiometer (MODIS) 250m NDVI datasets and Landsat satellites image data in the upper stream of Yellow River. The exact study region is the area along the Yellow River from Liujiaxia hydropower station to Qingtongxia hydropower station (Liu~Qing section). The research adopted the rules of average in-year NDVI changes extracted from MODIS data to modify the NDVI calculated from Landsat satellite images of different months to obtain the spatial heterogeneity and temporal dynamics in vegetation variation. A series of statistical analysis were applied to the NDVI and weather characteristics to identify the relation between them. Compared to the effect of weather factors, the relations between hydroelectric development and vegetation cover changes were analyzed.
