地形决定地表水、热状况的再分配.地形地貌的变化往往影响到一个区域内土壤分布和土壤肥力的变化.不同土壤类型界线往往与反映不同地貌的等高线相适应.掌握反映地貌形态和变化的地形等高线的性质及地貌判读,对于分析区域内各种地貌单元与土壤分布的关系,勾绘土壤界线的走向,校核土壤图,以及剖面点和调查路线的布置,都是十分重要的.
Topography determines the redistribution of surface water and thermal conditions.Geographical changes often affect the distribution of soil and soil fertility in a region.The boundaries of different soil types tend to be consistent with the contour lines reflecting different topography.Gradually reflect the topography and The change of topographic contour and the interpretation of the geomorphic interpretation are very important for analyzing the relationship between various geomorphic units and soil distribution in the area, mapping the trend of soil boundaries, checking soil maps, and laying out profile points and survey routes important.
