Implementing adaptation in developed countries: an analysis of progress and trends     

FRÉDÉRIC GAGNON-LEBRUN  SHARDUL AGRAWALA 《Climate Policy》2013,13(5):392-408

Little attention has been paid thus far to the experiences of developed countries in adapting to climate change. This article addresses this research gap by providing an assessment of broad trends in progress on planning and implementing adaptation in developed countries. Primary inputs are the National Communications (NCs) by these countries to the United Nations Framework Convention on Climate Change (UNFCCC), although the article also discusses illustrative examples of recent adaptation activities that have not been covered in the NCs. NCs reflect ‘whole government’ perspectives and follow a standardized reporting format, which facilitates cross-national comparisons. The analysis shows that impacts and adaptation receive limited attention within NCs. The discussion on impacts and adaptation has typically been dominated by climate scenarios and impacts analysis, while the discussion on adaptation is often limited to the identification of generic options. There are signs of recent progress, however, in the Third and especially the Fourth NCs, in which a growing number of developed countries report on establishing frameworks for adaptation and on efforts to implement adaptation measures that take future climate into account. Although an encouraging sign, it is still too early to assess the eventual impact of such measures.  相似文献

多比例尺空间数据的表达与处理是GIS的一个固有问题,本文用土地信息多级网格代替多级土地数据库中的多比例尺数据库及其多比例尺表达,以解决多级土地数据库建库过程中制图综合带来的地类数据变化问题,同时也为土地数据的共享提供了方便.  相似文献   

The Tornado Hazard In Southern New England: History,Characteristics, Student And Teacher Perceptions     

《The Journal of geography》2012,111(6):258-266

Abstract

People generally do not perceive New England to be tornado-prone. Yet, there is a long history of such storms in the six states going back to the late seventeenth century. Usually, New England tornadoes are small and short-lived; even so, some have caused many deaths and much property damage. There is a greater probability for a person to be affected by a tornado in southern New England than in much of the American Midwest. As building and population density increases, so does the hazard potential. Data from awareness surveys indicate that the lack of tornado knowledge remains a serious problem for teachers, students, and the public, and government information about such storms is not being widely disseminated.  相似文献   

Mentoring: A New Approach to Geography Teacher Preparation     

《The Journal of geography》2012,111(3):105-112

Abstract

Geography teacher preparation is an ongoing problem for the discipline. Changes in certification requirements and federal and state educational policies have diminished the role of colleges and universities in educating teachers. At the same time, geography education reform efforts have resulted in higher standards and an increased quantity of geography in the curriculum, pre-service programs have failed to produce an adequate supply of highly qualified geography teachers. This paper suggests that geographers implement geography mentoring programs to improve the quality of geography instruction in early-career teachers. A model developed for the National Geographic Society is described. The model uses Teacher Consultants as mentors to assist novice teachers at the stage in their development when they are most ready to improve practice: between years two and five of their career.  相似文献   

莫莫格国家级自然保护区的鱼类多样性     

杨富亿  吕宪国  娄彦景  娄晓楠  薛滨  姚书春  肖海丰  王波 《湿地科学》2012,10(2):214-222

2008～2010年,在鱼类资源调查的基础上,分析了莫莫格国家级自然保护区的鱼类多样性特征。调查结果显示,莫莫格国家级自然保护区有鱼类物种5目11科42属49种,其中本区土著种5目10科38属45种,包括中国特有种4种,中国易危种5种,冷水种8种,国家II级保护动物1种。土著种群落中,有鲤形目(Cyprini-formes)鱼类32种,鲤科(Cyprinidae)鱼类29种,鮈亚科(Gobioninae)鱼类13种;古北界北方区黑龙江亚区黑龙江分区的物种为22种;源于东部平原和北方平原生态类群的鱼类有27种;适应于江—湖缓流环境和淡水定居生活的鱼类有33种;草上产卵和水层产卵繁殖的鱼类有37种;杂食性和初级肉食性种类有28种,它们均相对占优势。莫莫格国家级自然保护区与嫩江的鱼类群落物种结构Jaccard系数和Morisita-Horn相似性指数分别为0.918和0.838;稀有种(包括中国易危种)和常见种分别为14种和25种;物种多度格局近似于对数正态分布。这些结果表明,莫莫格国家级自然保护区的鱼类多样性与嫩江密切相关,鱼类区系复杂,物种组成与生态类型多样;群落结构相对较稳定,多样性程度相对较高,但仍面临着稀有种(包括中国易危种)尚占有一定比例而导致群落结构脆弱的潜在威胁。保持嫩江鱼类群落结构的稳定,对维护和发展莫莫格国家级自然保护区的鱼类多样性具有特别重要的意义。  相似文献

湿地遥感分类作为湿地管理、监测与评价的重要手段,受到了广泛的关注。遗传算法(GA)借鉴了生物进化规律进行启发式搜索寻优,支持向量机(SVM)是一种新型的空间数据挖掘方法,二者相结合可以发挥各自的优势,寻找到支持向量机的全局最优参数,从而较准确地对湿地进行遥感分类。以洪河自然保护区为例,采用遗传算法优化的支持向量机方法进行了湿地遥感分类研究。同格网搜索下的支持向量机湿地遥感分类及最大似然监督分类对比,结果表明,遗传算法优化较格网搜索方式总精度提高了7.29%,较最大似然监督分类提高了12.06%,方法改善了沼泽、草地与裸地三种地物间的区分,是湿地遥感分类的有效手段。  相似文献   

印度夏季风与中国华北降水的遥相关分析及数值模拟   总被引：4，自引：0，他引：4  

刘芸芸  丁一汇 《气象学报》2008,66(5):789-799

20世纪80年代中国学者揭示了印度夏季风与中国华北降水的正相关关系,以后国内外又有一些研究证实了这种正相关关系的存在.文中利用1951-2005年多种气象资料和数值模拟方法,详细讨论了印度夏季风和中国华北地区夏季降水的关系,并针对由印度西北部经青藏高原到中国华北地区形成的正、负、正的遥相关型,从动力因子和热力因子两方面探讨了其中的内在联系,所得结果不但确证了以往的结论,而且进一步揭示了印度夏季风对华北地区降水的影响机制.结果表明:(1)印度夏季风强(弱)时,华北地区容易出现降水偏多(少)的天气;华北地区降水偏多(少)时,印度夏季风偏强(弱)的机率却低一些,这说明印度夏季风的异常变化对华北地区夏季降水有更大的影响.(2)印度夏季风强度主要受印度季风槽的影响,在印度季风槽加深的同时,中高纬的低压槽也加深发展,而这时西太平洋高压脊西伸,来自低纬的西南风水汽输送和源于西太平洋的副热带高压南侧的东南风水汽输送共同作用,有利于华北地区的降水偏多;反之则不利于华北地区的降水.(3)区域气候模式模拟结果也很好地模拟出印度夏季风和华北夏季降水的遥相关关系,其相应的环流异常系统与诊断分析结果非常一致,这从另一方面证实了这种遥相关关系的存在和可靠性.  相似文献
