论我国河流水环境容量空间分异与工业生产力的宏观布局

在分析我国各地区经济发展与河流水环境容量资源之间矛盾关系及其成因的基础上,揭示了水环境容量与生产力宏观布局之间的关系,并探讨了根据河流水环境容量条件进行生产力宏观布局与调整产业结构的策略。水环境容量是影响生产力宏观布局的重要因素之一,在工业生产力布局时,如果能充分考虑水环境容量资源的承载力,则能够以最小的经济代价,换取最佳的环境效益,使经济与环境得以持续、协调发展,促进区域经济增长。     

新疆博格达山北麓山前断裂西段的断裂组成及其在全新世时期的活动

博格达山北麓山前断裂西段全长１４０ ｋｍ ,由５ 条雁列状排列的逆断裂组成。全新世时期,古牧地断裂的最新活动发生在６．８２±０．５４～４．８７±０．３９ Ｋａ Ｂ．Ｐ．之间;四工河口断裂切割Ⅱ级河流阶地,最新活动时间与古牧地断裂大体相同;泉泉子断裂切割Ⅰ级河流阶地,最新活动发生在３．７５±０．４１ Ｋａ Ｂ．Ｐ．;热水河断裂及东风牧场断裂由于缺乏断代年龄实测数据,无法对其最新活动时间作出判断,但是推断它们也是全新世活断裂     

Resource-based development in the Russian Far East: Problems and prospects

The paper examines the prospects for resource-based development in the Russian Far East. It adopts a critical perspective on the potential for resource-based development by examining problems with Far East resource industries, specifically by looking at the experience of the other resource economies more generally. In particular, it highlights the new geo-economic context for resource development in the Far East of Russia as the world economy approaches the much touted, and now questioned, ‘Pacific Century’.     

人口移动与区域经济格局变动

人口移动是我国近几年发生的重要社会经济现象之一,其机制是东部地区人多地少的推力与西部地区产业结构性空缺的吸力,以及国家对后者特定的工资与粮食政策。它对地域分工格局的变动产生着重大影响。     

Regional oceans governance mechanisms: A review

The development of regional governance for the protection of the environment, sustainable use of natural resources and conservation of its biodiversity is unquestionably a cornerstone of international environmental law and policy. With regard to marine and coastal issues, it has mainly been taking place through Regional Seas programmes, Regional Fishery Bodies and Large Marine Ecosystems mechanisms. Based on a similar geographical approach, however, these regional mechanisms raise concerns relating to their coordination and efficiency, and possibly overlap in what they aim to achieve. This paper provides a review of existing regional oceans governance mechanisms, assessing their individual and collective capacities to move towards ecosystem-based management, and highlighting options to make the regional landscape more coherent and effective.     

C波段雷达在新疆区域数值预报系统中的应用初探

基于新疆区域数值预报系统（Desert Oasis Gobi Rapid Analysis Forecast System,下称DOGRAFS）,开展了同化C波段雷达资料对2010年10月6日发生在新疆的一次强降水过程预报结果影响的试验分析。其中设计包括不同化任何资料、同化常规资料、同化雷达反射率因子、同化雷达径向风、同时同化反射率因子和径向风五组试验,重点分析了雷达资料同化对此次天气过程降水、温度以及风速模拟效果的影响。结果表明：（1）同化雷达径向风和同时同化径向风和反射率因子相对于其他三组试验,对降水预报的TS和ETs评分更高;（2）相对于其他三组试验,同化雷达径向风和同时同化径向风和反射率因子对模式垂直方向上的温度、风速预报偏差具有一定的改善效果;（3）对于地面2 m温度和10 m风速而言,同化常规观测资料比其他四组试验预报的平均偏差和均方根误差更小;其它四组试验误差相当,差别不明显,表明同化雷达对近地面层温度和风的影响不明显。本研究旨在探索C波段雷达观测资料在新疆区域数值预报系统中的适用性,为今后雷达观测资料在业务系统中的应用提供参考。     

On the recent warming of the southeastern Bering Sea shelf

During the last decade, the southeastern Bering Sea shelf has undergone a warming of 3 °C that is closely associated with a marked decrease of sea ice over the area. This shift in the physical environment of the shelf can be attributed to a combination of mechanisms, including the presence over the eastern Bering Sea shelf of a relatively mild air mass during the winter, especially from 2000 to 2005; a shorter ice season caused by a later fall transition and/or an earlier spring transition; increased flow through Unimak Pass during winter, which introduces warm Gulf of Alaska water onto the southeastern shelf; and the feedback mechanism whereby warmer ocean temperatures during the summer delay the southward advection of sea ice during winter. While the relative importance of these four mechanisms is difficult to quantify, it is evident that for sea ice to form, cold arctic winds must cool the water column. Sea ice is then formed in the polynyas during periods of cold north winds, and this ice is advected southward over the eastern shelf. The other three mechanisms can modify ice formation and melt, and hence its extent. In combination, these four mechanisms have served to temporally and spatially limit ice during the 5-year period (2001–2005). Warming of the eastern Bering Sea shelf could have profound influences on the ecosystem of the Bering Sea—from modification of the timing of the spring phytoplankton bloom to the northward advance of subarctic species and the northward retreat of arctic species.
