| 摘 要： | 基于地貌学及分形理论,利用GIS技术和回归统计方法,以陕北黄土高原丘陵沟壑区12个样区1∶1万地形图为数据源,对该区以分形维数为量化指标的区域地貌形态与土壤侵蚀模数关系进行了初步探讨,给出地貌形态分形维数与土壤侵蚀模数之间的关系模型.研究结果表明:地貌分形维数可以作为预测区域土壤侵蚀程度的地貌指标.

| Abstract: | Based on geomorphology,fractal theory,geographic information system (GIS) and regression statistics,the relationship between regional landform which quantified by fractal dimension and soil erosion modulus was set up in 12 sample areas of hilly and gully region,Loess Plateau,north Shaanxi province. It was proved that landform fractal dimension can be used as an indicator to predicate the soil erosion degree in typical morphologic region of Loess Plateau. |
