摘要：

摘 要：受复杂多变的地形地貌影响和制约，目前我国丘陵山区土地整理项目工程布局的科学性与合理性难以得到保证。本文以长阳土家族自治县土地整理项目为例，借助计算机软件强大的三维建模与空间分析功能，对项目区地形进行三维模拟，通过空间分析绘制项目区剖分坡度分级图，在此基础上对项目区工程布局进行科学论证分析并提出合理化建议。研究结果表明，借助计算机软件的三维空间分析功能，可以有效提高丘陵山区土地整理工程设计精度和工作效率，促使土地整理工作整体科技水平的提升。

Abstract:

Abstract: Affected and restricted by the complex topography，it is difficult to guarantee the scientificalness and rationality of the layout of land consolidation projects in hills and mountainous areas nowadays in our country. This paper taked Changyang county’s land consolidation project as a case, with the help of computer software, using its three-dimensional modeling and spatial analysis functions to make 3D simulation of the project area terrain and to draw the project area subdivision slope classification map. On this basis, analysed the projects layout of the area scientifically and made some reasonable suggestions. Research results show that, using the three-dimensional spatial analysis function of computer software, can effectively improve the design accuracy and efficiency of the hilly area of land consolidation projects and can promote the whole scientific and technological level of land consolidation work.
