| 摘 要： | 为了揭示植被覆盖以及土壤导水系数变化对流域水文的影响,用陆面模式SSiB4与动态植被模型TRIFFID和流域地形指数水文模型TOPMODEL的耦合模型(SSiBT/TRIFFID)进行流域植被覆盖与土壤导水系数变化对流域水文影响的数值试验。结果表明:①植被类型明显影响流域地表能量平衡和水量平衡;②流域森林植被能明显减小一般洪峰流量,但对大的洪峰流量没有减弱作用;③减小土壤导水系数将明显增加地表径流和减小基流。

| Abstract: | In order to examine and analyze the effects of vegetation cover and soil transmissivity on hydrological processes at basin scale,the coupled model SSiB4T/TRIFFID(dynamic vegetation model TRIFFID and TOPMODEL are integrated into SSiB4) was used to conduct numerical simulation for effects of vegetation and soil transmissivity on hydrological in the Qingyijiang basin.The results of the simulations showed that: ①Vegetation type significantly affects energy and water balance of the basin;②Vegetation cover is able to reduce ordinary flood discharge obvously but it has no effects on great flood discharges;③Reducing soil transmissivity will increase surface runoff and reduce base flow significantly. |
