The Application of ARGO Data to the Global Ocean Data Assimilation Operational System of NCC

1. Introduction It is well-known that the state of ocean plays very important role in the climate change. But there is a paucity of the ocean observation data. The data distri- bution in the space, time and different components is very inhomogeneous, even in some areas, there are no any observation data. Hence, it brings some diffcul- ties to the scientists to study many problems relevant to ocean. This situation has been being changed since ARGO (Array for Real-time Geostrophic Oceanogra-…     

三峡水库区巫山新县城库岸综合治理设计回顾

三峡水库区巫山新县域库岸综合治理工程范围内涉及到滑坡、泥石流、塌岸等多种地质灾害。治理工程综合运用了多种技术与结构措拖，工程的复杂性和典型性在整个三峡库区具有极强的代表意义。笔者对整个治理方案的布置情况进行了归纳总结，并以翔实的第一手资料对治理工程设计过程中出现的几种典型问题一一进行了分析与论述．提出了相应的解决方案与合理化建议。结论认为，库岸综合治理工作，必须根据不同的地形特征，结合城区总体布局及沿线市政工程建设，综合考虑，有机结合，做到治理和利用相结合，最大限度地改善新城建设用地环境和城市生态环境。设计人员必须依照现场实际条件进行动态设计，确保工程方案合理、可靠、经济。文中讨论的问题和实践经检对同类工程具有一定的借鉴意义。     

浅谈省级地震系统如何做到开发富局

作为财政拨款公益性事业单位,省级地震系统实现开发富局,应该要从稳定项目收入,拓展自营收入,培育和发展生产点,推进制度创新着手。本文试图从预算和管理的角度对其作一点简单分析。

地理信息产业技术公共服务平台评价方法研究

福建省地理信息产业技术公共服务平台是福建省科技厅产业技术公共服务平台建设项目。要充分发挥该平台在推动地理信息产业发展中的作用,集聚产、学、研各方优势资源,提升中小企业的技术水平和创新能力,就要在交易平台中设计一套完善的评价方法,促进交易平台上交易双方不断提升自己的服务能力。本文介绍了常规电子商务网站的评价体系和存在的普遍性问题,并根据实际对本平台评价方法进行了初步设计。     

2000～2015年会理县地表覆盖变化监测

以LandSat多时相影像为数据源,采用基于规则的面向对象分类方法,监测会理县2000～ 2015年地表覆盖变化.结合1∶50 000 DEM数据,分析了会理县地表覆盖构成与转移、变化动态度及潜在退耕地情况.监测分析结论能为会理县加强空间管制、促进土地资源集约利用、指导生态文明建设等提供决策信息支撑.     

War,by Conservation

In this paper I argue that there has been a critical shift towards war by conservation in which conservation, security and counter insurgency (COIN) are becoming more closely integrated. In this new phase concerns about global security constitute important underlying drivers, while biodiversity conservation is of secondary importance. This is a significant break from earlier phases of fortress conservation and war for biodiversity. In order to develop a better understanding of these shifts, this paper analyzes the existing conceptual approaches, notably environmental security which seeks to understand how resources cause or shape conflict, and political ecology approaches that focus on the struggles over access to and control over resources. However, this paper indicates the limitations of these existing debates for understanding recent shifts, which require a fresh approach. I chart the rise of the narrative I call poachers-as-terrorists, which relies on the invocation of the idea that ivory is the white gold of Jihad, a phrase which is closely associated with an Elephant Action League (EAL) report in 2012 which claimed Al Shabaab used ivory to fund its operations. This narrative is being extended and deepened by a powerful alliance of states, conservation NGOs, Private Military Companies and international organizations, such that it is shaping policies, especially in areas of US geo-strategic interest in Sub-Saharan Africa. As a result conservation is becoming a core element of a global security project, with significant implications for conceptual debates and for conservation practice on the ground.     

云南富宁县水合口矿化蚀变信息提取和找矿预测

云南富宁水合口金矿位于滇东南文山―富宁成矿带,属于著名的滇黔桂"金三角"地区。利用landsat 8OLI遥感影像对研究区进行1∶100 000矿化蚀变信息提取,结合区域地质和化探异常等多元信息进行找矿预测,表明矿化蚀变、断裂构造交汇处和地球化学异常空间叠加部位为有利找矿地区,圈定了5个找矿远景区,为研究区开展下一步找矿提供了科学依据。     

矿床成矿系列——五论矿床的成矿系列问题

矿床的成矿系列(简称成矿系列)是矿床学领域的一个理论性概念,由五级序次组成。矿床成矿系列是成矿系列的第二序次,是成矿系列的核心部分。矿床成矿系列的划分,以岩浆、沉积、变质、表生和流体(非岩浆-非变质成因流体)5种成矿作用为基本原则,以成矿地质环境为基础,结合成矿的时段与形成的矿床组合进行划分。本文对矿床成矿系列时空范围、时空组成结构、矿化强度与演化、成矿区带内不同矿床成矿系列之间的演化、叠加和复合作用及对指导找矿的意义进行了论述。     

国际油气井钻头进展概述 (四)——PDC钻头发展进程及当今态势（下）

近年来,非平面PDC切削齿,如浅凹面PDC齿、Stinger毒牙中心锥形齿、Stinger毒牙刀翼锥形齿、AxeBlade斧式脊形PDC齿和StayCool保持冷却PDC齿等制造的钻头,逐步在油气钻井中得到有效的应用。这些钻头能够以较高的钻进效率和工作寿命钻进某些硬岩和研磨性地层。为了满足水平钻井,特别在页岩气水平井中能够强力排除岩屑,并具有优良的钻井导向性能,国际著名公司推出了许多新型钻头,如ONXY Ⅱ矛式PDC钻头、Seeker导向PDC钻头、CounterForce反力PDC钻头、Speed快速PDC钻头等用于当代油气钻井,取得了良好的效果。文章还介绍了Defyer DPA套管钻头与CuttPro PDC防剪切保护帽。提出了以下建议：继续深入研究PDC钻头,以提高其性能,更好地满足油气钻井的要求;组合化钻头是油气钻头发展的重要趋势;比金刚石性能更好的钻头切削材料有可能今后发现或合成,可用于制作更佳钻井钻头;我国钻头企业需重组和发展状大;各种钻头技术创新应该加强。
