| 1 | Effects of stand characteristics on tree species richness in and around a conservation area of northeast Bangladesh显示文摘We investigated the effect of tree cover,forest patch and disturbances on tree species richness in a highly diverse conservation area of northeast Bangladesh.A systematic sampling protocol was adopted and 80 sub-plots from twenty five 1 ha plots were used for the vegetation survey.Linear regression analysis was performed to understand the effect of patch area,disturbances and tree cover on tree species richness.Ordination using Redundancy analysis(RDA) and Non-metric Multi Dimensional Scaling(NMDS) were also performed to explore the tree species compositional similarities along the stand characteristics gradient and locations of the sample plots.Our study revealed that,forest patch size has greater influence on species richness.Areas with medium level of disturbances have shown greater species richness.In constrained ordination the selected explanatory variables regulated the richness of common species.Our findings can be useful for better forest management and restoration of landscapes of conservation needs using ecologically important species. | Muha Abdullah Al PAVEL SharifA.MUKUL Mohammad Belal UDDIN Kazuhiro HARADA Mohammed A.S.ARFIN KHAN | 2016 | Journal of Mountain Science2016，13，6： | 2 |

| 18 | 线结构异向介质在天线小型化中的应用显示文摘本文综述萨格勒布大学承担的用于波导喇叭天线小型化的线结构ENZ异向介质的理论和实验研究。实现了两个工作在IOGHz的小型化喇叭天线,即嵌入单线ENZ板的喇叭天线和嵌入双线ENZ板的喇叭天线,其长度分别是最佳喇叭的52%和33%。它们的测量增益和全长最佳喇叭非常接近(0.1dB以内),但是带宽比较窄(5%~12%)。最后介绍喇叭天线小型化设计中线介质的简单Drude模型应用的理论研究结果。结果显示只有当导线以90°的角度连接到金属板上时其Drude模型才是精确的。即便如此,初步设计阶段使用Drude模型仍是不错的选择,所需的天线特性可由其他理论优化来实现。 | Silvio Hrabar Davor Bonefacic Damir Muha 刘利娜(译) 袁渊(校) | 2010 | 空载雷达2010，，4： | 0 |
| 19 | Tree species diversity in relation to environmental variables and disturbance gradients in a northeastern forest in Bangladesh显示文摘Biodiversity has become an issue of global attention because of growing awareness of its importance and its rapid depletion worldwide.Diversity of tree species in relation to environmental and disturbance gradients was examined in three managed forests.Trees were randomly sampled in a survey of 75 circular plots(radius=13 m)with 5 subplots(radius=1 m).Generalized linear model analysis was used with a Poisson distribution log link function to understand the effects of variables(organic matter,organic carbon,nitrogen,potassium,pH,elevation and disturbance)on tree species richness.Canonical correspondence analysis was used to explore ecological relationships among plots.Our result found that the stand characteristics was an important influencing factor in the three forests.Our result showed that the variables had a highly positive influence on tree species richness in the three forests.In ordination,the selected variables governed the richness of tree species.Our study can help identify the most important factors that drive tree species richness in the three managed forests in Bangladesh and in similar ecosystems and inform forest management decisions for conservation according to ecological importance. | Md Anwar Hossain Muha Abdullah Al Pavel Kazuhiro Harada Carl Beierkuhnlein Anke Jentsch Mohammad Belal Uddin | 2019 | Journal of Forestry Research2019，30，6： | 0 |
