Calculation indicated that there is 11 . 2295 million cubic meter slided loess from 1980 to 1998 . the area and the volume of yuan becomes smaller and smaller , and yuan edge becomes backward continuously due to the happened frequently loess landslide 近年来，黄土滑坡的滑动土体共达1122 . 95万m3 ，滑坡使塬面面积不断缩小，塬边不断后退。
The main region of landslide in southern yuan of jingyang is concentrated on the zhaitou , miaodian and jiangliu village in recent years . the landslide in southern yuan of jingyang can be divided into three period , 1982 - 1984 , 1992 - 1993 and 1996 - 1997 泾阳南塬塬边黄土滑坡在空间上集中分布在寨头村、庙店村和蒋刘村一带；在时间上表现为三个活跃期(即： 1982 1984年， 1992 1993年和1996 1997年) 。
By investigating and analyzing typical watershed on gully and rolling loess region , and gullied loess plateau , the paper preliminarily defines the measure and combination of comprehensive harnessing ways of soil and conservation 摘要通过对黄土高塬多沙粗沙区涉及较多的黄土丘陵沟壑区和黄土高塬沟壑区几条典型小流域和现有治理模式的调查分析，初步确定了多沙粗沙区两个主要侵蚀类型区的水土保持措施组合方案。
After dry season , the soil moisture changes as the follow trend : gully slopes > hills > upland > hillslopes , while after rainy season , it is as follows : gully slopes > upland > hills > hillslopes . in addition , the soil moisture has obvious vertical distribution characteristic in the slope 一般规律是：旱季之后，土壤含水量表现为沟坡梁顶塬面梁坡；雨季之后，土壤含水量表现为沟坡塬面梁顶梁坡。
The method can be used to compute large residual static corrections in complex 3d near - surface areas such as areas covered by desert and gebi . 5 ) based on 2d refraction statics method in cmp domain , 3d refraction static method of cmp domain is presented 该方法是在二维基础上发展的，在折射界面起伏不大的情况下，它可以同时解决三维cmp道集中长波长静校正和短波长静校正问题，可适用于塔里木沙漠、长庆黄土塬覆盖区。
The stability of yuan edge slope is assessed and plotted out by means of the theory of fuzzy information optimization processing and research in outdoors . at last , the corresponding geo - environmental preservation - cure measurements in southern yuan of jingyang are put forward 其中，直接经济损失840 . 09万元，间接经济损失211 . 9万元；应用模糊信息优化处理方法，结合野外地质调查对塬边斜坡稳定性进行了区划，提出了相应的治理措施。
The analysis on structure of land type show that the land structure is very complicated , landform is crash , land type is various , each area has great differences the platform land type area is 77 . 36 percent of total area and it is predominate 土地类型的结构分析表明，试区土地结构复杂，地形破碎，土地类型繁多，面积差异悬殊，其中台塬地类占总面积的77 . 36 ，占优势地位；平坦条田的分布较广较细碎，出现频率最高；沟坡地类是最复杂、最破碎的类型。
According to physiognomy , the bulk density changed as the following order : upland > hills > hillslopes > gully slopes , the saturated soil moisture arranged as : hillslopes > hills > gully slopes > upland , while field capacity and wilting moisture are as follows : gully slopes > hills > hillslopes > upland 在地貌上，土壤容重呈现出塬面梁顶沟坡梁坡，饱和含水量呈现出塬面沟坡梁顶梁坡，田间持水量和萎蔫湿度均呈现出沟坡梁顶塬面梁坡的趋势。
But the conflict between them was appeared during our research in field and the discussion with others . it is followed that the former with the rolling bedrock , the mid with mild bedrock and the latter with the stable bedrock relatively . the conflict between two conclusion above arise , what relationship between loess landforms and their bedrock exist 但在野外调查及同其他学者交流中发现两者并非总体对应一致，显示出陕北黄土高原南部黄土塬基底起伏相对较大，北部黄土梁状(为主)丘陵沟壑区及黄土峁状(为主)丘陵沟壑区基底相对平坦的特征。
Jin tai taoist temple locates at northern of baoji city , shannxi province , built between yuan and ming dynasty . from then on , and each dynasty all have to set up or repair the buildings of jin tai taoist temple , now , there are 9 buildings with brick and wood , the construction two stores , add up to24 caves 金台观位于陕西省宝鸡市北部陵塬之半坡，始建于元末明初，几百年来，各朝均有增建修葺，流传至今，现存砖木结构建筑九座，窑洞殿堂两迭、上下计二十四孔。
