Review on Benefit Assessment of Soil and Water Conservation Measures in Gushanchuan River Basin

摘要

Benefit assessment of soil and water conservation measures in Gushanchuan River basin and corresponding assessment models were reviewed in the paper. Results show that different models led to different benefit assessment for Gushanchuan River basin. And the situation is partly due to shortcomings in statistic model itself and representatives of the employed data. Therefore, it is necessary to strengthen application research of physically-based hydrological models in the Loess Plateau instead of statistical models.
