| 1 | Disentangling the effects of topography and space on the distributions of dominant species in a subtropical forest显示文摘Topography and space are two important factors determining plant species assemblages in forest communities.Quantification of the contribution of these two factors in determining species distribution helps us to evaluate their relative importance in determining species assemblages.This study aims to disentangle the effect of topography and space on the distributions of 14 dominant species in a subtropical mixed forest.Spearman correlation analysis and the torustranslation test were used to test the species–habitat associations.Variation partitioning was used to quantify the relative contributions of topography and space at three sampling scales and three life stages.Correlation analyses and torus-translation tests showed species abundance was mostly correlated with topographic wetness index,vertical distance from the channel network and convexity.Variation partitioning showed that pure topography,pure space and spatially structured topography explained about 2.1 %,41.2 % and 13.8 %of the variation in species distributions,respectively.For nine species,total topography fractions peaked in 20 m quadrats.For ten species,the pure space fractions peaked in 50 m quadrats.For many species,the total topography fraction andthe pure space fraction were larger for the most abundant life stages,which reflected the importance of sampling effect.However,some cases did not follow this trend suggesting that the effects of ecological processes such as habitat filtering,density dependence or dispersal limitation may exceed the sampling effects.In conclusion,we found that spatially structured topography and pure space primarily shaped the distribution of dominant tree species.Furthermore,their effects were both scale- and life stage-dependent. | Qinggang Wang Yaozhan Xu Zhijun Lu Dachuan Bao Yili Guo Junmeng Lu Kuihan Zhang Haibo Liu Hongjie Meng Xiujuan Qiao Handong Huang Mingxi Jiang | 2014 | Chinese Science Bulletin2014，59，35： | 16 |
| 2 | Subtle trap recognition based on seismic sedimentology- A case study from Shengli Oilfield显示文摘地震沉积科学用地震数据是沉积岩石和外形的学习。然而,经常,沉积身体特征不能被描述份量上由于地震分辨率的限制。高决定倒置抵消这限制并且被用于地震沉积科学在复杂地质的条件下面识别微妙的陷井,从而拓宽地震沉积科学的适用的范围。在这篇论文,基于地震沉积科学,地震控制阶段的非线性的随机的倒置被用来在 Shengli 油矿在 Chezhen 消沉预言 Es3 的沙的集团企业水库。厚度和在几个阶段的沙的集团企业身体的沉积微外形地图被钻介绍,几个微妙的陷井被预言并且验证。 | Huang Handong Zhang Ruwei Luo Qun Zhao Di Peng Yongmin | 2009 | Applied Geophysics2009，6，2： | 10 |

| 4 | Significant enhancement of UV emission in ZnO nanorods subject to Ga+ ion beam irradiation显示文摘在光电子的 ZnO nanomaterials 的应用仍然由于他们的不够的光致发光效率被限制。以便优化 ZnO nanorods 的光致发光性质,在与在不同离子精力(0.5 keV16 keV ) 的 Ga + 离子照耀的关联,在 Si 底层上种的垂直地排列的 ZnO nanorods 的紫外排放在现在的学习被调查。我们发现紫外紧张与增加 Ga + 离子精力很快增加了,直到它在 2 keV,在点,紧张比由成长得当的 ZnO nanorods 生产了那高约 50 倍附近的最大值。低精力的 Ga + 离子的轻轻的轰炸把缺点从 ZnO nanorod 表面移开。在另一方面, Ga + 离子植入进 nanorods,导致压缩紧张。在表面缺点和压缩紧张的介绍的移动之上的水晶格子的完美的安排是贡献紫外轻产生的重要改进的二个因素,这被相信。 | Boluo Yadian Rui Chen Hai Liu Handong Sun Qing Liu Chee Lip Gan Zhou Kun Chunwang Zhao Bin Zhu Yizhong Huang | 2015 | Nano Research2015，8，6： | 1 |

| 8 | Using Walkaway VSP technology to improve inversion resolution显示文摘Walkaway VSP technology is commonly seen in the seismic development stage in the middle and late stages of the oilfield.Its advantage over conventional zero-offset VSP and non-zero well-source distance VSP is mainly due to the higher coverage of the Walkaway VSP acquisition process and the larger acquisition range.The resolution and signal-to-noise ratio are higher.Walkaway VSP technology has a very good application effect on solving complex structural problems and thin interbed reservoir problems.This paper mainly introduces a VSP constrained sparse spike inversion method based on high-precision VSP data.For the data acquired by the eight-azimuth Walkaway VSP in a work area of Bohai Gulf,a new method of 3D seismic-VSP joint seismic inversion is established.In the application of the actual work area,good inversion results based on Walkaway VSP data were obtained,and a new R24 small layer above the top boundary of the NmRIll oil group was depicted.This result meets the needs of development seismic technology and is used to solve thin interbed reservoirs exploration problems that have very important practical significance. | Xingda Tian Handong Huang Yang Liu Tingen Fan Ziyao Xiong | 2021 | Earthquake Research Advances2021，1，S01： | 0 |
