DEM分析法在土地整理项目中应用

本文以江西省上饶县皂头等乡(镇)土地整理项目为例,探讨了数字高程模型在土地整理规划中的应用。通过项目区数字高程模型的建立,实现项目区地形的三维可视化地形分析,判断项目区地形现状,辅助土地整理规划辅助设计,为该类地区整理项目中总体规划方案确定、工程项目规划以及工程量测算等方面提供参考和依据。

Application of Digital Elevation model technology in Land Consolidation Programming

This paper introduces the establishing method of the Digital Elevation Model(DEM) based on MapInfo and probe on its application in Land Consolidation Programming. In China, land consolidation has contributed a lot to the realization of the rational disposition of land resource and to the improvement of the land use efficiency and the ecological environment.With the Geographic Information System (abbreviate GIS) development and land consolidation overall development, arrangement of work of technology, how be in an all-round way, a effective one apply GIS technology to the land consolidation, the work quality of improving the land consolidation programming has become the problem that relevant professionals care about and hope to solve gradually. Taking Shangrao county of Jiangxi province as an example, the application of GIS technique in land consolidation programming has been discussed in the paper. Though setting-up of the digitized map of project district, is it carry on introduction, manage, operate, analysis, show to geographical spatial datum to realize, can obtain land resource relevant information fast, can realize goal automation statistical and quantity charge to space, make a large amount of a abstract one, isolated data vivid, easy to observe and analysis.
