First of all , research on the engineering geology environment of the field , after the field survey , and detailed survey , finding out to pography and morphology in the field , the layer lithology geological tectonic the non - geology phenomenan . etc 首先对场区工程地质环境的研究，通过对现场调查和详细勘察，查明场区的地形地貌，地层岩性，地质构造，不良地质现象等，这是稳定性分析的基础。
Based on the actual situation in the upper reaches of minjiang river , the main assessment factors such as strata structure , landform , vegetation covering eco - environment , surface water , ground water , agrotype and geological hazard are selected in this paper 本文根据岷江上游的实际情况选取岩性构造、地形地貌、植被覆盖生态区、地表水、地下水、土壤类型及地质灾害等因素作为评价因子。
Mini - type wireless video transmission system not only can be used in military small - area battlefield scout , but also have great application foreground in different kinds of field , for example in traffic monitoring , disaster detecting and terrain reconnaissance 它既可以应用于军事小区域战场侦察任务,又能应用于交通监控,灾情勘察以及地形地貌勘测等民用任务,在众多领域均有巨大的应用前景。
Abstract : all kinds of natural and human factors , including climate , organism , landform , m other rock and material , and human disturbance , influenced the genesis and devel opment of soils in shunde ecological paradise , guangdong province 文摘:广东省顺德生态乐园内的土壤形成发育受气候、生物、地形地貌、母质母岩和人为干扰等5大因素的影响，其中人为活动是导致土层结构破坏和水土流失的主要原因。
Experts agree that debris flow forms and grows upon three basic conditions , i . e . , inducible landform , abundant material supply and adequate water flow . research in this paper is thus concentrated upon the environment from the geology and the three conditions 众多专家一致认为，泥石流的形成与发育必须具备三个基本条件：一是有利的地形地貌基础；二是丰富的补给物质条件；三是有适当的水源激发。
With objective oriented designing and programming , all functions of the visualization of 3d terrain & landforms are provided by component object model ( com ) . so , it is suitable for much more development tools , and it can be applied conveniently to secondary development 利用面向对象的设计与编程方法，以组件( com )的形式提供三维地形地貌可视化的各种功能，它适合于多种开发环境，便于开发者的二次开发。
The visualization research of 3d terrain & landforms is an important part of geographic information system ( gisk digital photography ( dp ) and remote system ( rs ) , and drawing a high realistic 3d graph is an important research project of computer graphic ( cg ) 三维地形地貌的可视化是地理信息系统( gis ) 、数字摄影测量( dp )和遥感系统( rs )的重要研究内容，其中高度真实感三维图形的绘制是计算机图形学( cg )的重要研究内容。
Extracting terrain data automatically with spatial analysis function of gis , then plan the dam system on 3d simulating dem , single dam is being designed in the virtual gullies by ways of humen - computer interaction , and output the engineering drawings 基于数字高程模型应用gis的空间分析功能,自动提取地形地貌数据。在三维仿真的dem上进行坝系规划,在虚拟现实的沟道中以人机交互的方式进行单坝设计,利用cad技术绘制输出工程图。
From the landslide investigation and data processing , the authors discussed the characteristics and distribution pattern of landslides , their formation conditions and mechanism , which are controlled with geological structures , lithological association , topography and rainfalls 通过对该区域内滑坡调查和已有资料的分析研究，结果表明，昆明市滑坡分布规律与特征受到地质构造、地层岩性组合、地形地貌、降雨四种自然因素的影响强烈。
According to the topography and geomorphology , the abnormality of gravitation and magnetic field , characteristics of crust structure and the environment of lithospheric dynamics in the northwestern of the south china sea , the seismic profiles were explained across the yinggehai basin and xisha trough 摘要本文根据南海西北部壳体的地形地貌、重磁场异常和地壳结构特征和岩石圈动力学环境，对穿过莺歌海盆地和西沙海槽的地震剖面进行解释。
