On the basis of the types of sand stone , light and heavy mineral associations , planimetric map of sedimentary facies and directions of palaeoflow , it is considered that detrital material of terrigenous deposit of chang6 - 8 oil - beds in this area come from southwest provenance , northeast provenance , west provenance and south provenance , respectively , which are the denudation area of huating - longxian county in southwestern , yinshan ancient land in the northern , the denudation area of yantong mountain and tongxin to the west of yangjiajuzi - yinjiacheng county and qinling ancient land in the southern 根据砂岩类型、轻、重矿物组合、沉积相带平面展布及古水流方向等特征的分析,认为研究区延长组长6 ? 8油层组陆源碎屑物质来自西南、东北、西部和南部四大物源区,分别为西南华亭?陇县一带剥蚀区,北部阴山古陆,西部的杨家咀子、殷家城以西的烟筒山、同心地区剥蚀区和南部秦岭古陆。

The function design of system includes writing down amendment and pretreatment about spatial database and attribute database . this system provides common and basic functions of gis . besides , we can make out the topographical maps , planimetric maps and skiagraph , structure objects of highway construction of design and can inquire two - way between spatial information and attribute information 系统功能设计包括空间数据库和属性数据库的录入、修改以及预处理;系统还提供了一般gis系统应具备的基本功能,并在此基础上进行涵盖公路设计施工的地形图、平纵缩图、构造物等图形信息与属性信息的双向查询,并运用挣值法等对相关属性进行分类统计以供有关公路工程项目的各方使用。

Test results show that spur dikes aligned along a single bank in the deep water zone have more effects on the adjustment of the bed topography of the wide - shallow river than in the shallow water zone ; alignment of spur dikes along both banks can effectively adjust the planimetric position of deep - water zone ; and a reasonable widening rate of the regulation line in the estuary can readjust the variation of the average water depth along the river 试验结果表明,在深水区的单侧丁坝群对宽浅河床地形的调整作用大于浅水区;双侧丁坝群的联合作用能调整深水区的平面位置;合理地选择治导线的放宽率,能有效地调整深槽平均水深的沿程变化。

Based on the direction of sources and the ratios of sandstone to formation of sedimentary rocks , together with the sedimentary structures and textures , paleocurrent direction and the characteristics of paleontology , etc . , the planimetric maps of sedimentary facies of each stages in the studied area are compiled in order to recognized the extension of dominant facies and the evlotionary history of sedimentary environment , hi the stage of benxi and taiyuan , lagoon - tidal flat sediments are widespread in the area , and the deposits of estuary , lagoon and small delta in the northwest margin of ordos 以物源方向和沉积岩砂地比值为基础,结合沉积结构构造、古水流方向及古生物特征等,编制了研究区各期次的沉积相平面图,以识别优势相展布和沉积环境演化。本溪期和太原期研究区泻湖?潮坪沉积分布广泛,西北缘发育河口湾、泻湖及小型三角洲沉积。
