THE POSSIBILITIES AND REALITIES ON THE REMANAGEMENT OF DESERTIFIED LANDS IN THE TRANSITIONAL ZONE BETWEEN THE DRY-FARMING AREA AND THE GRAZING AREA IN NORTH CHINA

The desertification process is rapidly developing at present and 61.5% of the land area in the zone are already desertified.Among the desertified lands, 26.9% are seriously desertified, 25% most seriously desertified and 47.4% are the lands where desertification is under way. They are caused by over-reclamation for farming, over-grazing, unreasonable collection of firewood,the destruction of vegetation and the misuse of water resources. Under the ecological environment in semi-arid zone,the degraded environment process possesses the ability of restoring to its original status as soon as the interruption of excessive human activities are eliminated. The fencing- and-self-cultivating method is an effective measure adopted universally in semi-arid zone to cure the desertified lands.The desertified lands can be readjusted and controlled easily if other controlling measures are supplemented. The fundamental ways to control desertification are to utilize rationally the resources, to readjust the existing land

Landslide distribution and sliding mode control along the Anninghe fault zone at the eastern edge of the Tibetan Plateau

Tibetan Plateau is known as the roof of the world. Due to the continuous uplift of the Tibetan Plateau, many active fault zones are present. These active fault zones such as the Anninghe fault zone have a significant influence on the formation of special geomorphology and the distribution of geological hazards at the eastern edge of the Tibetan Plateau. The Anninghe fault zone is a key part of the Y-shaped fault pattern in the Sichuan-Yunnan block of China. In this paper, high-resolution topographic data, multitemporal remote sensing images, numerical calculations, seismic records, and comprehensive field investigations were employed to study the landslide distribution along the active part of the Anninghe. The influence of active faults on the lithology, rock mass structures and slope stress fields were also studied. The results show that the faults within the Anninghe fault zone have damaged the structure and integrity of the slope rock mass, reduced the mechanical strength of the rock mass and controlled the slope failure modes. The faults have also controlled the stress field, the distribution of the plastic strain zone and the maximum shear strain zone of the slope, thus have promoted the formation and evolution of landslides. We find that the studied landslides are linearly distributed along the Anninghe fault zone, and more than 80% of these landslides are within 2-3 km of the fault rupture zone. Moreover, the Anninghe fault zone provides abundant substance for landslides or debris flows. This paper presents four types of sliding mode control of the Anninghe fault zone, e.g., constituting the whole landslide body, controlling the lateral boundary of the landslide, controlling the crown of the landslide, and constituting the toe of the landslide. The results presented merit close attention as a valuable reference source for local infrastructure planning and engineering projects.     

渗透作用下滑带细观结构演变特性

库岸滑坡受到库水升降作用影响, 内部渗透压力会产生周期性的变化。动态渗透压力会导致滑带结构与强度产生劣化, 进而影响滑坡整体稳定性。为揭示滑带在渗透作用下的结构演变特征, 通过室内渗流试验结合CT扫描技术获取了黄土坡滑坡滑带在不同渗流条件下的细观结构特征, 采用Avizo软件量化滑带细观结构参数, 定量分析了不同渗透条件下滑带结构的演变规律。结果表明, 滑带的渗透系数随渗流时长的增加而呈指数形式下降, 且水力梯度越大最终试样的渗透系数越小; 连续的CT重构图像显示渗流过程中部分黏土团聚体发生解体, 大孔隙被附近的细颗粒逐渐充填, 试样结构的宏观均一性增强; 统计数据表明滑带土的表观孔隙率由5%下降到了1%, 等效直径小于80 μm的孔隙占比随渗流时长的增加而增多, 而等效直径大于80 μm的孔隙占比随渗流时长的增加而减少。结果证明周期性渗透作用会影响滑带内孔隙结构的分布特征, 细观上表现为大孔隙被小颗粒充填, 导致渗流通道变得细长而弯曲, 孔隙的有效连通性被削弱, 宏观上表现为渗透系数随渗流时长的增加而降低。      

Estimating the maximum impact force of dry granular flow based on pileup characteristics

The maximum normal impact resultant force(NIRF)is usually regarded as the sum of the static earth pressure of the dead zone and the dynamic impact pressure of the flowing layer.The influence of the interaction between the flowing layer and dead zone on the impact force is ignored.In this study,we classified two impact models with respect to the pileup characteristics of the dead zone.Then,we employed the discrete element method to investigate the influences of the pileup characteristics on the impact force of dry granular flow on a tilted rigid wall.If the final pileup height is equal to the critical value,the maximum NIRF can be estimated using a hydrostatic model,because the main contribution to the maximum NIRF is the static earth pressure of the dead zone.If the final pileup height is less than the critical value,however,the particles in the dead zone are squeezed along the slope surface by the impact ofthe flowing layer on the dead zone,and because of shear effects,the flowing layer causes an entrainment in the dead zone.This results in a decrease in the volume of the dead zone at the moment of maximum NIRF with increases in the slope angle.As such,the maximum NIRF mainly comprises the instant impact force of the flowing layer,so hydro-dynamic models are effective for estimating the maximum NIRF.Impact models will benefit from further study of the components and distribution of the impact force of dry granular flow.

Zonal distribution of the erosion-landslide and soil micromorphological features in purple hilly region

In the purple hilly region, erosions and landslides are all serious, and it is of great scientific value and practical significance to study their formation mechanism and distribution features there.In this paper, soil micromorphological methods and techniques were used to study the erosion zonal distribution in the region. The results indicated: (1)According to erosion process, the spacial distribution zones of the erosions and landslides in the purple hilly region with different solums were divided into scouring erosion zone, transport-diffusion zone, rocks and soil turbulence zone and sediment-bury zone; (2) The soil micromorphologic taxonomic feature identifying different erosion-landslide zone were found by studying the soil micromorphology of erosive zone in purple hilly region; (3) As for the erosion-landslide formation in the region, besides the external factors, the internal factors were found more important and favorable for landslide formation through the studies on the micormorphologieal features of slide soil.

克拉通盆地盆缘致密气藏封堵模式: 以鄂尔多斯盆地北缘杭锦旗地区盒1段为例

克拉通盆地大面积致密砂岩气藏边界带上的气水分布往往远比盆地内部复杂, 圈闭类型多样, 气藏上倾方向封堵模式尚存在争议。本研究以鄂尔多斯盆地北缘杭锦旗地区二叠系盒1段气藏为例, 对比分析不同区带典型河道砂体厚度、岩相组合、砂体叠置关系、储层物性及横向宏观非均质性等多因素差异分布特征及其对气藏分布的控制作用, 最终建立杭锦旗地区不同构造带内盒1段气藏封堵模式。研究表明, 研究区自西向东发育3种河道沉积模式, 分别是西部缓坡区浅水辫状河模式、中部陡坡区冲积扇-辫状河模式、东部深水道模式, 3种沉积模式控制了河道上倾方向储层宏观非均质性差异, 这种宏观非均质性变化是研究区致密砂岩气藏上倾方向封堵的主控因素。根据研究区上倾方向储层变化与圈闭类型关系, 划分了3种天然气封堵模式: 西部缓坡区岩性封堵模式、中部陡坡区地层-岩性封堵模式、东部岩性-构造过渡封堵模式。3种天然气封堵模式构成了鄂北盆缘盒1段大面积天然气连续成藏区的边界, 同时控制了不同类型圈闭分布与天然气富集。
