A Model Korean Ubiquitous Eco-City? The Politics of Making Songdo

Building cities from scratch has continued unabated since the latter half of the twentieth century despite some of these planned cities achieving global infamy for their failures. These endeavors are, in part, due to a persistent belief by governments that newly constructed cities can set their nations on a fast path to the future. Today, challenges posed both by global climate change and increased urbanization have widened this platform from projects almost exclusively of developing nations to include those in the developed world. Today we talk of the eco-city, a local solution to a global crisis. If completion is successfully fast-tracked, the resultant eco-city will position its respective nation at the forefront of innovation in what is effectively a global race: the resultant city can be exported as a model both locally and globally. In this regard, the envisioning and building of Songdo in South Korea may not be unique. Songdo is a city underway on flat land created from wetland reclamation. As part of the Incheon Free Economic Zone (IFEZ), Songdo's development has benefited from opportunistic circumstances that has led to its pursuit of becoming a “Ubiquitous Eco-City.” The green infrastructure of the new city is to be enhanced by the provision of extra services that combine information and communication technologies as well as digital networks to ideally create harmony among the environment, society, and technology. Songdo, as planned, will position South Korea among a group of leading nations, and possibly at the forefront of new city development, potentially producing a model for export.     

Multi-level integrated planning and greening of public infrastructure in South Africa

The South African government has named the transition towards a greener economy one of its priorities. Meanwhile it has developed a new multilevel integrated planning process, and announced a massive public infrastructure investment plan. The converging point of these three dynamics should be the integration of green infrastructure principles into the different plans as the foundation of the green transition. This paper uses a policy integration analytical framework to assess whether this convergence is in fact taking shape. It analyses the level of integration of green infrastructure principles into the different plans and suggests options to move the green infrastructure agenda forward.     

傲雪凌霜 学者脊梁——孙筱祥先生对当代公园和植物园建设发展的开创性、前瞻性贡献及深远国际影响

【意义】随着国家植物园和华南国家植物园于2022年相继揭牌成立,当代公园和植物园的发展历程引起了更加广泛的关注。孙筱祥先生是中国现代风景园林领域的先驱和开拓者,其风景园林作品包括花港观鱼公园、杭州植物园、北京林业大学教学植物园、北京植物园（现国家植物园）、中国科学院华南植物园（现华南国家植物园）、海南植物园、厦门市园林植物园、深圳市仙湖植物园、中国科学院西双版纳热带植物园和云南景东亚热带植物园。纵观这些作品的诞生、演变及创作时代背景,系统性地总结孙先生的理论、实践和职业生涯,对于当代公园和植物园建设发展史的研究至关重要。【评论】孙筱祥先生集教育家、园林家、花卉家、画家、建筑师和大地规划师于一身,他的风景园林作品在时代洪流中脱颖而出,成为永恒的经典和传世之作。通过对孙先生70年风景园林史料的分析和研究,从聚焦时代背景的视角,阐述他为当代建设科学与艺术、东方与西方、古典与现代、自然与人文、抽象与现实相结合的世界一流公园和植物园开辟了道路、引领了方向、奠定了基础、树立了典范。【展望】孙筱祥先生的风景园林作品,遍布中国大江南北的不同气候带,他为促进植物多样性物种保存和迁地保护、人类生存环境的可...

晚清中国在巨文岛事件中的外交斡旋(1885-1886)

朝鲜问题一直是甲午战争前夕东北亚地区国际斗争的焦点之一,在中日双方就中朝宗藩关系体制的存废争执不休的同时,英国和俄国也为争夺对远东的控制而进行了明争暗斗。中国清廷在英俄两国之间展开外交斡旋,中国清廷本着维护中国对朝鲜的宗主权为出发点利用英俄两国的矛盾,使两国的争端得以缓和,最终以俄国允诺不侵占朝鲜领土和英国撤出巨文岛为结束。巨文岛事件的解决是晚清中国政府利用外交斡旋手段处理大国矛盾的比较成功的特例,但也使得清廷滋长了对未来朝鲜问题再度尖锐化的麻痹,盲目自信的态度也为日后甲午战争的外交失败埋下了伏笔。     

多角度同步反演在南海西部气田开发中的应用

在海上开发的油气田中,由于钻井数量．地震资料的应用在气田的管理中具有非常重要的作用．特别是在气田开发的中后期。常规的烃类检测技术和波阻抗反演技术已经无法解决储层物性横行变化的问题和剩余气分布的问题。通过采用多角度联合弹性反演技术获得的弹性参数来描述储层的物性变化和剩余油气分布．基本达到半定量的水平。为气田的下一步开发调整奠定了基础。研究表明．多角度同步弹性反演（AVA反演）得到的泊松比、纵横波组速度比可以定性识别含气储层和含水储层。利用纵横波组速度比与纵波波阻抗进行交会的办法可以半定量解释出气层的饱和度．反演结果可以用于未知目标的预测。     

Instrumental neutron activation analysis of beachrock samples of South East Coast of Tamilnadu, India

Element profiles of some beach rock samples collected from South East Coast of Tamilnadu, India have been determined using single comparator method of INAA. The geo-chemical behavior of the elements in the region is discussed. The irradiations were done at thermal neutron flux of ~ 1011 cm-2·s-1 at 20kW power using Kalpakkam Mini Reactor (KAMINI), IGCAR, Kalpakkam, Tamilnadu, India. Around 19 elements have been determined from 15 samples by high-resolution gamma spectrometry. The accuracy and precision were evaluated by assaying the irradiated Standard Reference Material (SRM 1646a Estuarine sediment) and were found to be in good agreement with certified values.
