利用气象研究与预报（WRF）大气模式，研究了索科托里马河流域（SRRB）土地利用-土地覆盖变化（LULCC）的影响，生成了WRF水文（WRF- hydro）模型的参数，该模型包括一个水平分辨率为12km的母域，其中包含更新的MODIS土地利用（LU）数据，以及以SRRB为重点的4km分辨率的嵌套域。通过修改入渗参数和曼宁粗糙度参数对模型进行校正。采用WRF-Hydro模型对城市（Ur）、草原（Gr）、稀树草原（Sa）、森林（Fr）和荒地（Ba） 5种不同的LU情景进行模拟。在分析时段内，Gr情景的模拟增加了所有预测点的流量，而Sa情景则减少了流量。在所有LU情景下，输入降水与径流之间存在较强的相关性，而在Ur、Fr和Ba情景下，输入降水与径流的比流量（SDR）显著相关。枯水期由于植树造林导致流量增加，由于毁林导致流量减少。草原转化为稀树草原的地区蒸散发ET略有增加，湿润期Sa情景的ET大于Gr情景，而干旱期Gr情景的ET大于Sa情景。研究表明，蒸散发是引起流域陆流变化的主要因素。模型对LULCC影响的敏感性是合理的，但建议更多的研究与LULCC影响研究中常用的不同水文模型的结果进行比较。气象研究与预报（WRF）水文模型；土地利用-土地覆被变化；流速及流水量;稀树大草原;草原。
This research investigated the effects of Land Use Land Cover Change (LULCC) over the Sokoto Rima River Basin (SRRB) using a setup of Weather Research and Forecasting (WRF) atmospheric model to generate the parameters to force WRF hydrological (WRF-Hydro) model which comprises of a parent domain at 12km horizontal resolution with an updated MODIS Land Use (LU) data and the nested domain at 4km resolution which focuses on the SRRB. The calibration of the model was done by modifying the infiltration and the Manning's roughness parameters. WRF-Hydro model was used to run simulations with the control LU and five different LU scenarios generated for Urban (Ur), Grassland (Gr), Savanna (Sa), Forest (Fr) and Barren (Ba). For the period analysed, simulation with Gr scenario increased streamflow in all the forecast points, while the Sa decreases it. A strong correlation was noted between the input precipitation and streamflow for all LU scenarios, and a significant Specific Discharge to Rainfall (SDR) for Ur, Fr and Ba scenarios. There was an increase in streamflow in the dry period due to afforestation and a decrease due to deforestation. Areas where grasslands were converted into savanna showed a little increase in evapotranspiration ET. There was more ET for the Sa scenario than the Gr scenario in the wet period, while there was more ET in the dry period for Gr scenario than it is for the Sa scenario. The study has shown that ET is a major factor to changes in streamflow due to LU changes over the basin. The sensitivity of the model to LULCC is reasonable, but more research is recommended to compare results with different hydrological model popularly used for LULCC impact studies.
