| Abstract: | [Objective] The vegetation greenness dynamics and attributions of land use/cover change in Bashang Plateau were analyzed, in order to provide scientific reference for the construction of local ecology and the environment support area for Beijing-Tianjin-Hebei region, and to support decision-making for land use planning and ecological environment protection.[Methods] MODIS MOD13Q1 NDVI dataset and Landsat-derived land use data in Bashang area were used to analyze the change trend of vegetation greenness during 2000-2019 and its attribution by linear tendency estimation and partial derivative attribution method.[Results] The average vegetation greenness during the main growing season (April to October) was generally high in the east, while low in the west of the plateau. Moreover, the average vegetation greenness was the highest on the woodland, while the lowest on the cultivated land. During 2000-2019, the maximum and the average NDVI in Bashang area showed an obvious increasing trend, with the rates of 0.063/10 a and 0.044/10 a, respectively, and areas with significant improvement of vegetation greenness accounted for 60%~83%. According to the quantitative analysis of the interannual land use and land cover changes in Bashang Plateau, the contribution rate of cultivated land, woodland and grassland was 50.51%~57.22%, 21.73%~28.62% and 14.41%~15.07%, respectively, during 2000-2019. The total contribution rate of water area, construction land and unused land was only 6%.[Conclusion] During 2000-2019, cultivated land contributed the most to vegetation greenness increase in Bashang area of Hebei Province, but the contribution rate shows a downward trend, and the contribution rates of woodland and grassland increases gradually. |
