| 摘 要： | 为分析土地覆被变化的水文效应.构建4种土地覆被情景,采用BTOPMC模型对淮河流域黄泥庄集水区1982-1986年的日径流过程进行模拟.结果表明,土地覆被变化对蒸散发量和径流量计算影响显著,与现状覆被情景的模拟结果相比,森林覆被情景蒸散发量增加,径流量减少,而林地草原和耕地覆被情景下情况相反,且各土地覆被变化情景下枯季径流深的变化幅度明显小于雨季的变化幅度.该模型能较好地分析和评价土地覆被变化下的径流响应.

| Abstract: | To examine the effects of land cover change on hydrologic process, the BTOPMC model is applied to simulate the daily runoff in the study area controlled by the Huangnizhuang Hydrologic Station in the period of 1982-1986 based on four land cover scenarios. The results show that the land cover change influences the calculation of evapotranspiration and runoff obviously. Compared with the current land cover scenario, the evapotranspiration of the forest scenario increased and the runoff of it decreased. The ca... |
