“传统”农业景观旅游保护困局的反思（英文）

全球范围对"文化景观"重新燃起兴趣需要从多维方式来解释。传统栖息地,人民和他们在特殊环境里的生活方式的价值改变过程是和与遗产地有关的"文化、社会和经济建设"的引入密不可分的。自上世纪90年代开始,文化景观作为一种新型遗产列入联合国教科文组织世界遗产名录,它强调人类与环境相互作用的重要性,需要了解景观在时空上的动态性。观念的变化产生了对标志性景观和传统社区的"动态保护"。从交叉学科的视角来理解这一交互过程对规划和保护可持续遗产景观至关重要。遍及全世界的各试点项目和案例研究都引起了关于遗产景观的可持续性和旅游的至高无上作用的批判性反思。全球重要农业文化遗产(GIAHS)能否受益于旅游产生的经济资源,需要基于研究的方法来分析机会和预期,评估其战略政策和自上而下的政策。

天然气水合物沉积物力学性质的试验研究

利用研制的天然气水合物沉积物合成及力学性质一体化试验设备,以粉细砂土作为土骨架,分别对冰沉积物以及对四氢呋喃(THF)、二氧化碳(CO2)和甲烷3种水合物沉积物进行了室内合成和三轴剪切试验,分析和比较了这4种沉积物样品的应力-应变和强度特性,初步探究了冰和不同气体在水合物沉积物强度中所起的作用。试验结果表明：4种沉积物均表现为塑性破坏;围压越大,水合物沉积物强度越高;在水合物含量相同条件下,不同气体水合物会使水合物沉积物的强度不同。

Quantitative application study on remote sensing of suspended sediment

Quantitative application on remote sensing of suspended sediment is an important aspect of the engineering application of remote sensing study.In this paper,the Xiamen Bay is chosen as the study area.Eleven different phases of the remote sensing data are selected to establish a quantitative remote sensing model to map suspended sediment by using remote sensing images and the quasi-synchronous measured sediment data.Based on empirical statistics developed are the conversion models between instantaneous suspended sediment concentration and tidally-averaged suspended sediment concentration as well as the conversion models between surface layer suspended sediment concentration and the depth-averaged suspended sediment concentration.On this basis,the quantitative application integrated model on remote sensing of suspended sediment is developed.By using this model as well as multi-temporal remote sensing images,multi-year averaged suspended sediment concentration of the Xiamen Bay are predicted.The comparison between model prediction and observed data shows that the multi-year averaged suspended sediment concentration of studied sites as well as the concentration difference of neighboring sites can be well predicted by the remote sensing model with an error rate of 21.61% or less,which can satisfy the engineering requirements of channel deposition calculation.     

Transportation development transition in China

Scientific development is an invaluable asset to a country.Policies and development modes should be carried out based on scientific findings not only in industry,but also in transportation infrastructure construction.Building an integrated transportation system,which is in line with the national requirements of China and supports sustainable socio-economic development,is a key strategic issue related to building a moderately prosperous society and achieving realistic goals of a medium-level developed country.Based on a systematic review of the advances in China’s transportation infrastructure over the last 60 years,this paper explores the main drivers of transportation development,including national policy,transportation structure,investment efficiency,and technological innovation.Analysis shows that China’s comprehensive transportation infrastructure construction since 1949 can be divided into five stages initiated by these drivers,which correspond to four transition modes:policy transition,structural transition,efficiency transition,and technology transition.The transition path of China’s transportation development shows that the dominant factors have changed,and the interval for each transition has shortened.With the implementation of the ’12th Five-Year Plan’,China’s transportation infrastructure construction is showing some new characteristics and facing a new development transition.Finally,this paper analyzes the trends in transportation development in China and concludes that technological innovation will be the main driving force to increase the transportation supply and service area in the future.

大井坡航空地球物理试验场典型剖面综合地球物理解释

全面采集并分析我国首个航空地球物理综合实验场(大井坡实验场)的地质和地球物理特征,综合地质、地形、遥感、磁、重力和电磁等资料,在试验场内选取3条典型剖面,以电阻率测深剖面为约束,采用多边形2.5D棱柱体模型组合法建立典型剖面地质-地球物理模型;对剖面进行重、磁联合正反演,并通过剖面与平面相互验证的方式,开展重、磁、电综合解释研究。通过研究,全面掌握了试验场内断裂及岩性构造的分布规律,试验场被中部近EW向和北部呈NEE向展布的两条断裂分割成南部褶皱区、中部断隆区和北部坳陷区3个区域,为试验场综合解释填图提供了依据和约束条件。
