摘 要: | 对地貌空间结构特征进行分析,可以揭示土壤侵蚀的机制、强度和空间分异,预测土壤侵蚀的发展趋势。研究表明,地形相对高差、坡度、沟壑密度与年土壤侵蚀量之间均有良好的相关关系,据此可建立地表形态各要素与年土壤侵蚀模数之间的数学模型。从地貌空间结构特征预测土壤侵蚀发展趋势具有一定的可行性。

Study of Forecasting Soil Erosion from the Characteristic of Space Structure of Greomorphology |

Abstract: | The mechanism, intensity and space distribution of soil erosion can be revealed and its teden-cy be predicted by analyzing the characteristic of space structure of geomorphology. Studies showed that there was a good correlation between relative difference of height, slope gradient, gully density and annual amount of soil erosion. According to this, a mathematical model which re-fleets the relation between the factors of surface configuration and annual soil erosion can be established. It is possible to some degree to forecast the tendency. |
