Bringing Systematic Thinking of Landscape Justice Into Global Design Practice

Design increasingly plays a pivotal role in achieving justice for all.However,there are often gaps between visions and implementation due to the variety of factors and stakeholders involved in design practice.Through literature review and a keyword co-occurrence analysis,this paper investigates current landscape justice research and identifies the distinguishing concerns in design,and highlights the importance of systematic thinking in achieving landscape justice.By examining the practices of the British company Building Design Partnership(BDP),a multinational design company,this paper identifies BDP’s three key design principles as experiences can be followed for landscape justice:design for inclusion,design for resilience,and design for future ecosystems.The paper also addresses potential challenges and conflicts in implementing landscape justice across different contexts and highlights multinational design companies’efforts to mediate between various stakeholders.Finally,this paper demonstrates that design companies can contribute to 1)bridging social and environmental justice through landscape design,2)achieving the visions promoted by scholars,3)identifying and deploying diverse approaches to achieving landscape justice with their sensitivity to practical problems,and 4)fostering integrated feedback loops via both top-down and bottom-up approaches to ensure effective implementation of landscape justice.

Strategic Thinking on Shallow-water Oil and Gas Exploration in Offshore China

The oil and gas exploration in offshore China has made great achievements,and as the important areas of offshore exploration,the shallow waters contribute most of the oil and gas reserves and production.However,the available area for exploration is diminishing and the cost of exploration is rising.The field changes and ever increasing difficulties of exploration bring new challenges technically and economically.Therefore,for effective exploration of shallow-water oil and gas in offshore China,it is necessary to center on the general requirements of becoming a powerful marine country and the ideas of value exploration,initiate key research projects in the fields of China's offshore stratigraphic-lithologic reserves,Paleogene reserves,buried-hill reserves,high temperature and pressure reserves and hydrocarbon-rich sags,and form geological theories and explorative technologies of large and medium size oil and gas field in offshore China.The measures regarding the challenges include:(1) Innovating theoretical understanding and optimizing new exploration fields,(2) developing technical capabilities and improving the success rate of exploration,and(3) enhancing management level and deepening value exploration.

伊犁盆地南缘阔斯加尔地区砂岩型铀矿勘查历程与找矿启示

阔斯加尔地区是近年来在乌库尔其铀矿床往东探索扩大而新发现的砂岩型铀成矿地段。文章通过对阔斯加尔地区不同勘查阶段工作部署以及找矿思路的梳理,结合矿体地质特征,归纳总结铀矿体发现的经验和启示。阔斯加尔地区于20世纪50年代开始勘查工作,前期探索查证为后期的铀矿勘查工作提供了线索和依据。2008年开始带钻查证工作,通过资料梳理,重新预测了铀成矿潜力地区,落实了铀矿产地;2012-2013年进入瓶颈期,经历综合研究和系列基础图件编制,细化了控矿因素,预测了成矿有利地段;2016-2020年为突破期,矿体规模持续扩大,连续揭露到多个较富大的矿体,平米铀量持续提升,资源量规模达中型。阔斯加尔地区是伊犁盆地南缘“乌库尔其-蒙其古尔中部矿集区”的重要组成部分,西接乌库尔其矿床,南邻扎吉斯坦矿床,是伊犁盆地南缘“外围找矿,就矿找矿”的重要地区。中侏罗统西山窑组上段铀矿体为区内主要矿体,其规模较大,资源占比高。通过对已知矿床外围进行不断的探索和查证,搜集整理老资料、开展综合研究与编图等重要的经验和启示,可以作为寻找类似铀成矿地区的借鉴。
