Fig.5. Spatial and temporal distribution characteristics of dune movement around Longyangxia Reservoir from 1987 to 2019 using COSI-Corr (A, D, G and J are the vector diagrams of the moving rate and direction of dunes in the local area of upwind; B, E, H and K are the vector diagrams of the dune movement of the study area in1987-1995, 1995-2003, 2003-2013 and 2013-2019; C, F, I and L are the vector diagrams of the migration rate and direction of dunes in the local area of downwind) |
