依据现有研究基础和国家有关规范,提出基准地形起伏度(Basic Topographic Relief)的概念,并设定以国家基准公里格网为基础,基于1∶5万比例尺基本地形图上10 m等高距的矢量化等高线,采用TIN插值方法,构建10 m分辨率的DEM,再通过100 m×100 m地理格网作为计算依托格网,以内部高差3.5 m作为平地条件,计算公里格网的地形起伏度,为当前地形起伏度的研究提供必要的规范性前提和计算标准。选取区域内部空间差异较大的大连旅顺口区作为案例区进行实证研究,佐证了基准地形起伏度概念和模型的可操作性,同时也为本区域的科学发展及发展规划的制定提供依据。

Concept of basic topographic relief is proposed in this article according to existing research foundation and relevant state regulations. On the basis of 1∶50 000 plotting scale based on benchmark km grid and vector contour lines of 10 m contour interval on basic topographic map,using TIN interpolation method to establish DEM of 10 m resolution,by And calculate topographic relief of km grid through 100 m×100 m geographic grid as a calculation based on grid,altitude difference within 3.5 m as ground conditions,calculating topographic relief of km grid. This can provide necessary standardization premise and calculation standard for current research of topographic relief. Selecting Lushunkou District with big interior special difference as a case for empirical research,supporting operability of concept and model of topographic relief,and also provide basis for scientific development and establishment of development plan of the region.
