| 1 | Sedimentary architecture models of deepwater turbidite channel systems in the Niger Delta continental slope,West Africa显示文摘This paper studied an architecture model of turbidite channel systems based on the shallow- layer high resolution 3D seismic information in the deepwater area in the Niger Delta continental slope, West Africa as a prototype model. Different types of channel systems were identified and the corresponding architecture models were established. The controlling factors, evaluation criteria and spatial distribution of different channel systems were analyzed. This study shows that turbidite channel systems of West Africa could be classified into three types; confined, semi-confined and unconfined, according to the condition of canyon and the levees on both sides. On one hand, along the transport direction, channel system evolves from confined to unconfined. Within channel systems, channel complexes, including two types of incised and enveloped, are the most important reservoir bodies. On the other hand, there is a channel complex evolution from incised to enveloped vertically. The geological factors exert impacts of different levels on the architecture of the turbidite channels in different sedimentary systems or even within the same system. | Liu Li Zhang Tingshan Zhao Xiaoming Wu Shenghe Hu Jialiang Wang Xing Zhang Yikai | 2013 | Petroleum Science2013，10，2： | 16 |
| 2 | Characteristics and accumulation mechanism of tight sandstone gas reservoirs in the Upper Paleozoic, northern Ordos Basin, China显示文摘The Ordos Basin is a significant petroliferous basin in the central part of China.The Carboniferous and Permian deposits of transitional and continental facies are the main gas-bearing layers in the north part of the basin.The Carboniferous and Permian natural gas reservoirs in the northern Ordos Basin are mainly tight sandstone reservoirs with low porosity and low permeability,developing lots of 'sweet spots' with comparatively high porosity and permeability.The tight sandstones in the study area are gas-bearing,and the sweet spots are rich in gas.Sweet spots and tight sandstones are connected rather than being separated by an interface seal.Sweet spot sand bodies are vertically and horizontally overlapped,forming a large gas reservoir group.In fact,a reservoir formed by a single sweet spot sand body is an open gas accumulation.In the gentle dipping geological setting and with the source rocks directly beneath the tight reservoirs over a large area,the balance between gas charging into tight reservoirs from source rocks and gas loss from tight reservoirs through caprock is the key of gas accumulation in tight sandstones.Both the non-Darcy flow charging driven by source-reservoir excess pressure difference and the diffusion flow charging driven by source-reservoir gas concentration difference play an important role in gas accumulation.The results of mathematical modeling indicate that the gas accumulation cannot be formed by just one of the above mechanisms.The diffusion of gas from source rocks to reservoirs is a significant mechanism of tight sandstone gas accumulation. | Liu Guangdi Sun Mingliang Zhao Zhongying Wang Xiaobo Wu Shenghe | 2013 | Petroleum Science2013，10，4： | 16 |
| 3 | Composite Sand Bodies Architecture of Deep-Water Turbidite Channels in the Niger Delta Basin显示文摘Deep-water turbidite channels have attracted much attention as a focused issue in petroleum exploration and development. Extensive studies have been performed on the architecture of turbidite channels, and most researches have focused on their geometric shapes, sedimentary processes and controlling factors. However, little attention has been paid to the distribution patterns, distribution laws and quantitative studies of composite sand bodies of turbidite channels. Taken one slope area of the Niger Delta Basin as an example, this study conducted a semi-quantitative to quantitative analysis on architecture of composite sand bodies of turbidite channels based on cores, well logging and seismic surveys. It is shown that turbidite channel systems can be classified as confined and unconfined channel systems. For confined channel systems, the vertical evolution process involves four stages. The sinuosity of a channel system is controlled by slope, with a negative power function relationship between them. When slope gradient reaches four degrees, the channel system is nearly straight. Based on the migration direction and migration amount of single channels within channel complexes, channel composite patterns can be divided into four classes(the lateral composite, en-echelon composite, swing composite and vertical composite) and several subclasses. Various channel composite patterns show specific distribution laws spatially. For meandering channel complexes at the middle-late evolution stage of confined channel systems, the lateral migration amongst single channels shows the features of integrity and succession. The sinuosity of single channels in the late period is greater than that in the early period, and cut-offs may occur locally when the sinuosity is larger than five degrees. This study provides a better understanding for the geological theory of deep-water sedimentary, and also improves exploitation benefits of this type of reservoirs. | LIN Yu WU Shenghe WANG Xing LING Yun LU Yao ZHANG Jiajia YU Zhi | 2014 | Acta Geologica Sinica(English Edition)2014，88，6： | 9 |
| 4 | The regional types of China's floating population: Identification methods and spatial patterns显示文摘With the rapid increase of the number and influence of floating population in China,it is urgently needed to understand the regional types of China's floating population and their spatial characteristics. After reviewing the current methods for identifying regional types of floating population,this paper puts forward a new composite-index identification method and its modification version which is consisted of two indexes of the net migration rate and gross migration rate. Then,the traditional single-index and the new composite-index identification methods are empirically tested to explore their spatial patterns and characteristics by using China's 2000 census data at county level. The results show:(1) The composite-index identification method is much better than traditional single-index method because it can measure the migration direction and scale of floating simultaneously,and in particular it can identify the unique regional types of floating population with large scale of immigration and emigration. (2) The modified composite-index identification method,by using the share of a region's certain type of floating population to the total in China as weights,can effectively correct the over-or under-estimated errors due to the rather large or small total population of a region. (3) The spatial patterns of different regional types of China's floating population are closely related to the regional differentiation of their natural environment,population density and socio-economic development level. The three active regional types of floating population are mainly located in the eastern part of China with lower elevation,more than 800 mm precipitation,rather higher population densities and economic development levels. | LIU Shenghe HU Zhang DENG Yu WANG Yingjie | 2011 | Journal of Geographical Sciences2011，21，1： | 8 |
| 5 | Field Modeling Method for Identifying Urban Sphere of Influence:A Case Study on Central China显示文摘With rapid development of urbanization and regional interaction and interdependence,regional urban agglomeration planning becomes more and more important in China,in order to promote integrated development of various cities with close interrelationship.However,it is still arguable academically on how to define the boundary or which cities to be included for the urban agglomeration of a region.This paper aims to shed lights on how to identify urban spheres of influence scientifically by introducing field modeling method and by practicing a case study on 168 cities in Central China.In our field modeling method,the influence intensities of cities were measured by a comprehensive index and urban spheres of influence were represented spatially by field intensity.Then,their classification and spatial distribution characteristics of study area in 2007 were identified and explored by using GIS and statistical methods.The result showed that:1) Wuhan is the absolute dominant city in Central China;2) the provincial capital cities dominate their own provinces and there are no other lower grade agglomeration centers;and 3) the basic types of organization form of urban sphere of influence are single-polar type,agglomeration type,close-related group type and loose-related group type. | DENG Yu LIU Shenghe WANG Li MA Hanqing WANG Jianghao | 2010 | Chinese Geographical Science2010，20，4： | 7 |

| 11 | Mega-towns in China:Their spatial distribution features and growth mechanisms显示文摘As a special outcome of urbanization,mega-towns not only play an important role in the process of socio-economic development,but also are important contributors to urbanization.Based on a spatial database of mega-towns in China,this paper explores the spatial distribution features and growth mechanisms of China’s 238 mega-towns using the nearest neighbour distance method,kernel density estimation,regression analysis,global autocorrelation,local autocorrelation and other spatial analysis methods.Results of spatial distribution features show that:(1)on the national scale,the existing 238 mega-towns mainly gathered in the southeast coastal areas of China;they formed two spatial core agglomerations,several secondary ones and a southeast coastal agglomeration belt;(2)on the regional scale,each economic region’s index was less than 1,indicating that mega-towns in each region tended to be spatially agglomerated due to the close relationship with regional development level and their number;(3)on the provincial scale,68%of provincial-level units in China tended to be a spatial agglomeration of mega-towns;only one province had a random distribution;the number of mega-towns in those evenly-distributed provinces was generally small.The growth of mega-towns was determined by a combination of various natural and humanistic factors,including topography,location,economy,population,traffic,and national policy.This paper chose digital elevation model(DEM),location advantage,economic density,population density,and highway density distribution as corresponding indicators as quantitative factors.By combining their local autocorrelation analysis,these factors all showed certain influence on the spatial growth of mega-towns and together scheduled it.In the future,provinces and cities should make full use of the mega-town functions to promote their socioeconomic development,especially the central and western regions in China. | WANG Xueqin LIU Shenghe QI Wei | 2020 | Journal of Geographical Sciences2020，30，7： | 1 |

| 14 | Protection of urban features during urbanization based on the roles of springs in Jinan显示文摘Thirty-seven years since reform and opening up, China has sustained rapid economic growth and urbanization. However, there was inadequate protection of natural, historical, and cultural heritage, especially in the past 17 years, which led to the outcome that urban and rural construction lacked features. To rebuild our urban features during urbanization, and avoid destroying them,we should probe into the reason of lacking features and how to protect them. Therefore, taking Jinan City as an example, this paper explored the crisis and its causes of urban characteristics during the period of rapid urbanization based on discussing roles of spring features, including economic effects, social effects, ecological effects and so on. What is more, this paper listed and analyzed those protection measures taken by Jinan. The results showed that spring groups spewed again and kept for 8 years through those measures, which meant that urban characteristics restored. Thus, Jinan City provides successful and significant reference for other cities in restoring urban features during urbanization construction. Also, the author deemed that cities could recollect their urban features as long as they take reasonable measures. | Xueqin Wang Chengxin Wang Botao Wang Shenghe Liu Jinping Song | 2017 | Chinese Journal of Population,Resources and Environment2017，15，2： | 0 |
| 15 | Continuous SiC skeleton reinforced highly oriented graphite flake composites with high strength and specific thermal conductivity显示文摘Highly oriented graphite-based composites have attracted great attention because of their high thermal conductivity(TC),but the low mechanical properties caused by the inhomogeneous distribution and discontinuity of reinforcements restrict the wide applications.Herein,continuous SiC ceramic skeleton reinforced highly oriented graphite flake(SiC/GF)composites were successfully prepared by combining vacuum filtration and spark plasma sintering.The effect of SiC concentration on the microstructure,flexural strength,and thermophysical properties of the composites was investigated.The GF grains in the composites exhibited high orientation with a Lotgering factor of>88%when the SiC concentration was≤30 wt%,and the SiC skeleton became continuous with the SiC concentration reaching 20 wt%.The formation of continuous SiC skeleton improved the flexural strength of the composites effectively while keeping the TC in a high level.Especially,the composites with 30 wt%SiC exhibited the flexural strength up to 105 MPa,and the specific TC reaching 0.118 W·m^(2)·K^(−1)·kg-1.The composites with excellent flexural strength and thermophysical properties showed significant promise for thermal management applications. | Xiaoyu ZHANG Wenqi XIE Lan SUN Zhilei WEI Zhejian ZHANG Yuanyuan ZHU Jiabin HU Shenghe WANG Zhongqi SHI | 2022 | Journal of Advanced Ceramics2022，11，3： | 0 |
