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.
