| 英文摘要 | Sediment yield (SY) is affected by many components, such as topography, climatic phenomena, land use (LU), and soil characteristics, but it is significantly influenced by complicated interactions between climate, LU, and topography. In the current research, InVEST SDR model was utilized to investigate the climate change (CC) and land use change (LUC) contribution to sediment yield effects in a great sub-basin of the Caspian Sea in the north of Iran. Accordingly, five distinct scenarios were extracted and utilized for modeling purposes. The initial two scenarios pertained to the effects of CC, while the third scenario focused on LUC. The final two scenarios involved a combination of both CC and LUC. The results depicted a decreasing and negative impact on SY by CC, while LU had an incremental and positive impact. However, the impact of LUC was more severe comparing to CC. Under scenario 1, compared with the current situation, sediment retention increased by only 0.1%, while sediment exports and total potential soil loss decreased by 0.24% and 0.11%, respectively, but under scenario 2, sediment retention, sediment exports, and total potential soil loss decreased by 19.08%, 19.23%, and 19.25%, respectively. In scenario 3, sediment retention decreased by only 0.78%, while sediment exports and total potential soil loss increased by 22.04% and 21.48%, respectively. Under scenario 4, sediment retention decreased by only 0.76%, but sediment exports and total potential soil loss increased by 22.56% and 21.223%, respectively. Also, under scenario 5, sediment retention, sediment exports, and total potential soil loss decreased by 19.72%, 1.35%, and 1.85%, respectively. The estimation of CC/LUC influence on SY could assist managers and policymakers to have a better comprehension of sediment production processes and help them to manage and control sediment export in watersheds. |
