Ecohydrology combines the studies of hydrological and ecological processes and their interrelations in soil and water. It aims at a better understanding of hydrological factors determining the development of natural and human-driven terrestrial ecosystems, and of ecological factors influencing the hydrology. This paper analyzes the understanding of ecohydrological process by researchers from ecohydrology connotation view. Terrestrial landscape ecohydrology research is a hotspot. This paper summaries the ecohydrological process advances of mountainous region, wetland, dry land and basin integration modelling, analyzes the strategy of establishing ecohydrological model, gathers part of developed ecohydrological models, considers the three problems in model establishment, scales, data, definition. We should pay more attention to the following four aspects: ①the basic research on ecohydrological process;  ②the integration modeling research on ecohydrological process;  ③ecohydrological process on-line coupling research with database and GIS/RS technologies;  ④ecohydrological process research combining with prototype observation. To establish ecohydrological models that accord with local condition is the important task in today′s China ecohydrology research.
