| 英文摘要 | The impacts of deforestation, afforestation, dams, conversion to agriculture, urbanization, and the collective land use/cover change (LUCC) impacts on hydrology in large river basins are reviewed and summarized. Because most studies reviewed have focused on the changes in annual streamflow instead of flow regime in a basin, general conclusions cannot be drawn for flow regime. Deforestation (afforestation) increases (decreases) annual streamflow but there is no linear relationship between the deforested (afforested) coverage and the relative annual streamflow change. Impacts of conversion to agriculture on hydrology is complex and is dependent on the preagriculture land cover. When forest converts to agriculture, and as the cultivation degrades soil over the time, agriculture results in elevated annual streamflow. Urbanization increases peak flow, and the increase is linearly related to the urbanized area in a basin. Outstanding issues regarding land use/cover change impacts include: (1) feedbacks in large river basins; (2) basin internal spatial pattern of the land use/cover change impacts on hydrological processes; (3) incorporating the changes in soil hydraulic properties into hydrological modeling; (4) uncertainties in hydrological models; (5) considering both anthropogenically induced biophysical changes and natural long-term growth in LUCC impact studies for large basins. |
