| 摘 要： | 应用分布式水文模型SWAT进行了晋江西溪流域1985和2001年两期土地覆被条件下的产流产沙模拟,分别从整个流域尺度和子流域尺度定量分析了不同土地覆被类型的水文效应。结果表明,土地覆被变化对于整个流域产流量影响不大,对产沙量影响显著。不同子流域的产流产沙变化分析结果表明,其他条件相同的情况下,林地相对于其他土地覆被类型具有明显的减水减沙作用,其次是园地,再者是耕地和草地。建设用地在各土地覆被类型中增水增沙作用最为显著。 |
| 关 键 词： | 土地覆被变化 SWAT 子流域 产流量 产沙量 |

| Abstract: | In order to evaluate the influences of land-cover changes on surface runoff and sediment yield,two different land-cover data(1985,2001)in Xixi watershed of Jinjiang Basin were applied to the distributed SWAT(soil and water assessment tool)model.Quantitative results were obtained separately for the whole basin and subbasins.The results show that the effects of land-cover change was little to the runoff yield,while was significant to the sediment yield on the whole basin.Land-cover changes in sub-basins indicated that forest was the most important land use type for decreasing the runoff and sediment yield,orchard is the second,and followed by farmland and grassland.On the contrary,construction land contributed most for the increase of runoff and sediment yield. |
| Keywords: | land-cover changes SWAT sub-basins runoff yield sediment yield |
