Abstract. The response of vegetation system to the long-term changes in climate, hydrology, and social-economy in a river basin is critical for sustainable river basin management. This study aims to investigate the evolution of natural and crop vegetation systems in Heihe River Basin (HRB) over the past 2000 years. Archived Landsat images were applied to derive vegetation spatial extent and biomass for 1987 to 2015. The area and biomass of the vegetation before 1987 were reconstructed based on previous research results the derived relationship between the vegetation biomass and climatic and hydrological variables in the last 30 years with instrumental data. The key findings are: 1) both natural and crop vegetation have gone three development stages: Pre-development stage (before 1949), rapid development stage (1949–2000), and post-development stage (after 2000); 2) there was a much faster increase of crop biomass than that of native vegetation since 1949, and 3) the ratio of natural vegetation to crop vegetation decreased from 16 at Yuan Dynasty to at about 2.2 since 2005. This ratio represents the land and water development at river basin at changing climate and social-economy, it could be used as an indicator to plan the objective or examine the outcome of water and land management at river basin.

Short summary
This study aims to investigate the evolution of natural and crop vegetation systems over the past 2000 years accommodate with the changes in water regimes at the basin scale. It is based on Remote Sensing Data and previous historical research. The methods developed and the findings obtained from this study could assist to understand how current ecosystem problems were created in the past and what their implications for future river basin management are.
