地形分布 meaning in English
topographic distribution
topographical distribution
Examples
- After analyzing urumqi historical evolution and development processes of the urban morphology , spatial characters , and mechanisms and factors , the paper brings out some suggestion of city plan and construction , and propose the conceiving plan of the urban developing orientation in the future
32 ，分布在起伏度指数7上的土地所占比重最大，占14 54 。全研究区地形分布表现出低、中、高三段式空间分布结构。 - 2 the productive afforestation during timber production period from medium 1960 s to 1970 s and the continually protective afforestation after the setting up of the nature reserve were the primary causes of the significant variation for vegetation distribution pattern along topographic gradients during the study period . furthermore , natural recovery process also gave an impulse to the pattern changing . some obvious phenomena of human impact on natural vegetation can also be watched in our working area . decreasing of coniferous forest and broad - leaved forest with the simultaneous increasing of shrub reflected the type and spatial characteristics of human disturbance activities in working area . the related management department should consider the above problems more seriously
结果表明： 1 20世纪60年代中期大规模森林砍伐活动使林地的分布格局受到强烈干扰，这种影响一直延续到80年代中期2研究时段内的生产性育林活动保护性育林活动和自然植被恢复过程，对森林植被类型的地形分布格局产生了显著的影响3保护区目前仍存在着一些显著的人为干扰现象，针叶林及阔叶林比重的减少和灌丛数量的相应增加，反映出保护区目前人为干扰活动的主要类型和空间分布特征，应当引起管理部门的足够重视。 - Nondimensional distribution index was able to describe the spatial pattern of each landscape patch type and indicate the affection of the topography on the change of the pattern . for excluding the disturbance of the area , distribution index can describe the difference between the actual distribution and the standard distribution of each patch type on the topographic gradient . and according to this , kinds of comparative analyses were availed
运用地形分布指数克服了不同地形因子各梯度内面积的差异，同时也消除了各景观斑块类型的面积比重差异，能够准确地反映不同景观斑块类型在一定的地形因子梯度上的实际分布情况与标准分布的偏差，使分析不受面积的影响，其结果具有较好的可比性和可解释性；且通过对优势分布范围、分布趋势线特征的分析，能够获得森林景观空间分布格局及其变化的多种信息。
