1Spatial-temporal Characteristics of Land Use Intensity of Coastal Zone in China During 2000–2010显示文摘Based on remote sensing and GIS techniques, land use maps in 2000, 2005 and 2010 in China′s coastal zone were produced, and structural raster data of land use were further generated to calculate land use intensity comprehensive index(LUICI) for analyzing land use spatial-temporal characteristics at 1 km scale. Results show that: 1) from the perspective of spatial patterns of landforms at a macro scale, there is a significant difference in land use intensity between the north and the south of China′s coastal zone. Hotspots of changes mainly concentrated in metropolitan areas, estuaries and coastal wetlands; 2) elevation is an important factor that controlling land use spatial patterns at local scale. Land use intensity is much higher within areas below the elevation of 400 m and it decreased significantly as the elevation increasing; 3) there is a significant land-ocean gradient for land use intensity, which is low in island and near-shore areas, but high in the regions that 4–30 km far away the coastline because of much intensive human activities; however, in recent decades land use intensity had been promoted significantly in low near-shore area due to extensive sea reclamations; 4) significant differences of land use intensity were also found among provincial administrative units. A rising trend of land use intensity was found in provincial-level administrative units from 2000 to 2010. To sum up, elevation, land-ocean gradient, socio-economic status and policy are all influencing factors to the spatial patterns and temporal variations of land use intensity in China′s coastal zone.DI Xianghong HOU Xiyong WANG Yuandong WU Li 2015Chinese Geographical Science2015,25,1:20
2Characteristics of coastline changes in China's Mainland since the early 1940s显示文摘Based on multi-temporal topographic maps, remote sensing images and field surveys covering the entire coastal zone of China's Mainland, the coastlines of six periods since the early 1940 s were extracted. Coastline changes over the last 70 years were then analyzed in terms of coastline structure, coastline fractals, coastline change rates, land-sea patterns, and bay areas. The results showed that mainland coastline structure changed dramatically, and due to the significant coastline artificialization mainly driven by sea reclamation and coastal engineering, the remaining natural coastline merely accounts for less than one third at present. Coastline fractal dimension represented an overall spatial pattern of 'north < entirety < south'; however, the discrepancy between the north and south coast was apparently narrowed due to dramatic coastline artificialization of northern China which in turn altered the whole pattern. Patterns and processes of land-sea interchange along the mainland coast were complex and varied spatially and temporally, with over 68% advancing toward sea and 22% retreating toward land. The net growth of land area was nearly 14.2 ×103 km2 with an average growth rate of 202.82 km2 a??; and coast retreat was characterized by area decrease of 93 bays with a magnitude of 10.1 ×103 km2 and an average shrinking rate up to 18.19% or an average shrinking speed up to 144.20 km2 a??, among which the total area of Bohai shrunk by 7.06%, with an average annual loss amounting to 82 km2. The dramatic coastline changes along China's Mainland have brought about kinds of challenges to the coastal environment, therefore the integrated management, effective environment protection and sustainable utilization of coastlines is urgent.HOU XiYong WU Ting HOU Wan CHEN Qing WANG YuanDong YU LiangJu 2016Science China Earth Sciences2016,59,9:18
3Cardinal roles of miRNA in cardiac development and disease显示文摘MicroRNAs(miRNAs) are small noncoding RNAs that are emerging as pivotal modulators in virtually all aspects of cardiac biology,from cardiac development to cardiomyocyte survival and hypertrophy.The miRNA profiling,following gain-and loss-of-function studies using in vitro and in vivo models,has identified wide-ranging functions for miRNAs in the heart,providing new perspectives on their contributions to cardiac pathogenesis,and revealing potential therapeutic targets and diagnostic biomarkers.This review summarizes current progress in regulation of miRNAs in heart development and disease.FENG YuLiang YU XiYong 2011Science China(Life Sciences)2011,54,12:13
4Realizing high low-electric-field energy storage performance in AgNbO_(3) ceramics by introducing relaxor behaviour显示文摘Both sustainable development in environment and safety of high-power systems require to develop a novel lead-free dielectric capacitor with high energy density(Wrec)at low applied electric field.In this work,a remarkably high Wrec of 2.9 J/cm^(3) accompanying with energy storage efficiency of 56% was achieved in Ag_(0.9)Sr_(0.05)NbO_(3) ceramic at a low applied electric field of 190 kV/cm,by improving antiferroelectricity and introducing relaxor behaviour.The improved anti-ferroelectric stability was attributed to the decreased tolerance factor and average electronegativity difference,while the relaxor behaviour was associated with the increased disordered local structure by Sr-doping.Moreover,the Ag_(0.9)Sr_(0.05)NbO_(3) ceramics also exhibited outstanding temperature stability in energy density with small variation less than 5% over 20-140℃.The results indicate that the Ag_(0.9)Sr_(0.05)NbO_(3) ceramic is a promising candidate for low-electric-field driving capacitors.Kai Han Nengneng Luo Shuaifei Mao Fangping Zhuo Xiyong Chen Laijun Liu Changzheng Hu Huanfu Zhou Xinpeng Wang Yuezhou Wei 2019Journal of Materiomics2019,5,4:5
5Mechanism of surface texture evolution in pure copper strips subjected to double rolling显示文摘Developing ultra-thin copper foils with different surface roughness and microstructure has important significance for improving the service performance and reducing the production cost of high-end circuit boards. In this paper,pure copper strips with initial cube texture were subjected to a double rolling process(deformation amount ranges from 50% to 95%),and the surface textures evolution law and mechanism of doublerolled strips were studied by an X-ray diffraction technique. The results show that when a deformation amount increased from 50% to 70%,the grains of two surfaces rotate away from the cube orientation,and the formed textures of two surfaces mainly consisted of C,S and B orientation components. The orientation density values for these three components on bright surface only had slight difference; the orientation density values for C and S components were much larger than that for B components on a matt surface. When the deformation amount increased to 90%,the increase extents of orientation density values for C and S components were obviously larger than that for B components on a bright surface; the increase extents of orientation density values for these three components were almost the same on the matt surface. It has been found that when deformation amount reaches 95%,the grains orientation of bright surface were relatively concentrated,and the orientation density value for C texture obviously increased to 11.68 and that for B texture was only 3.15; the grains orientation of matt surface were relatively dispersed,and the orientation density value for C texture increased to 9.26 and that for B texture obviously increased to 6.35,and the density values of these two textures had less difference. For the condition of strong compressive and shear stress on the bright surface,grains were mainly rotating to C texture orientation; compared with the bright surface,'semi-free' deformation condition on the matt surface is beneficial to promote much more grains to rotate to the B texture orientation.Xiyong Wang Xuefeng Liu Jianxin Xie 2014Progress in Natural Science:Materials International2014,24,1:2
