摘要: The ecosystem along the lower reach of Tarim River has been undergoing remarkable changes due to ecological water conveyance activity since 2000. To improve scientific basis riparian restoration, clearing understanding dynamic eco-hydrological system and feedback between hydrological components are needed. A fully distributed model combines a hydrology component based on modified MODFLOW, with vegetation described by Verhulst logistic equation. validation using groundwater well observation, river stage observation remote sensing data demonstrated that good capability in simulating River. interaction revealed through balance analysis scenario studies. Vegetation significant impact evapotranspiration, storage change depth, while depth is critical variable determines dynamics, which shown simulation result. represented this study could help dependent restoration protection, particularly for ecosystem.
