| 摘 要： | 针对黄土丘陵区的土地可持续利用问题，引入目前国际上较先进的水土流失与土地利用规划模型APEX和AV-SWAT，利用GIS技术及陕北安塞县纸坊沟小流域定位站多年的连续观测资料，对模型在黄土丘陵区的适用性进行了初步验证。通过对该类型地区的水土流失量、作物产量、植被生物量等方面的测算，结果表明模型模拟计算的水土流失量与实际观测量的误差小于10%，5年加权平均的作物模拟产量与实测值的差异不显著。从而为该类型区土地可持续利用方法论提供了新的计算工具，也使得更大尺度上的土地可持续利用设计成为可能。

| Abstract: | Aimed at the sustainable land use on Hilly-Gully region of Loess Plateau, the computerized simulation model APEX and AV-Swat were introduced and revised. The applicability was validated using GIS technology and experimental data of Zhifanggou small watershed. The values of soil and water erosion, crop productivity and biomass were simulated, the results show that the difference is less than 10% between the measured values and simulated ones of soil and water erosion; and there is no significant differences between actual yields and simulated ones. The model could be used in the sustainable land use research of large-scale area. |
