| 摘 要： | 以淮河上游息县水文站以上流域为例,基于研究区域3期(20世纪80年代、90年代、2000年以后)土地利用数据及地形、气象、水文、土壤、农业管理等数据,应用SWAT模型模拟研究区域产汇流过程,分析土地利用变化对流域产水特性的影响。结果表明:在降水量、坡度和土壤质地相同的情况下,径流模数大小为旱地>水田>林地;在坡度和土壤质地相同的情况下,土地利用方式对降水量变化的产水敏感性为旱地>水田>林地(径流系数变化率),可见土地利用模式的变化可影响流域的产水特性,耕地向林地的转变将使流域产水减少。

| Abstract: | The Xixian hydrological station in the upper reaches of Huaihe River is selected as case study area. Three stages of land use (2000s, 1990s, 1980s), climate, hydrology, soil and agricultural management data are collected and the SWAT model is used to simulate the runoff process. And then the impacts of land use change on runoff characteristics are analyzed. The results show that under the same conditions of precipitation, basin slope and soil type, the runoff modules ranks as farmland, paddy filed and woodland; on the same conditions of basin slope and soil type, the sensitivity of land use change on runoff ranks as farmland, paddy filed and woodland (the change rate of runoff coefficients). Therefore, the land use change can affect runoff characteristics, and conversion of farmland into woodland will reduce the basin water yield. |
