宁夏灵盐地区荒漠化灾害与农牧业持续发展

分析了宁夏灵盐地区荒漠化灾害过程中自然环境与人力活动的相互作用，并讨论了区域农牧业经济发展的“退耕还牧”治沙等社会问题。在第四纪地质时期荒漠化的发生发展是一种“气候－地貌”的自然过程；在人类历史时期是气候主控下人为叠加干扰的“自然－人为”地貌过程。自然环境与人为活动具有使荒漠化发生正向或逆转变化的双重机制。     

造山带岩浆活动与构造运动关系研究综述

熔体及其活动在造山带的演化中发挥了重要作用。熔体活动发迹了地壳应力作用方式而诱发形成剪切带或断层；熔体活动调整块体间的位移而影响造山带的变形；     

岩浆活动旋回与地球多层对流系统

从地球历史的节律角度讨论岩浆活动旋回。岩浆活动旋回可按时间与空间分出相互对应的不同尺度，进而可与深度尺度不同的地球多层对流系统相互对应，从而给予了岩浆活动旋回的动力学意义。岩浆活动的时间周期愈长，空间尺度亦愈大，需要的维持岩浆源存在的热能、挥发分供给的数量与深度亦愈大。     

陕西省区域环境地球化学分区

为了利用地壳元素分布特征与动植物微量元素含量间的关系,指导生态环境综合治理,借助已有的基础地球化学资料,进行陕西省地球化学分区,确定各分区的环境背景值、污染起始值、缺乏临界值、过剩值临界值,并将陕西省分为陕北、关中、陕南3个地球化学区,圈定了1个元素贫化区和2个元素富集区。提出应该在元素的缺乏和过剩的异常区内进行生物体内微量元素含量的定期检测。做到对地球化学疾病及时发现及时寻找对策,以保证人类生存环境的安全,提高生存质量。     

应用MapGIS构建上海及邻近海域地震与新构造活动关系数据库

基于MapGIS构建上海及邻近海域地震和新构造活动数据库。该数据库由空间和属性两大数据库组成。其中，空间数据库包括地理底图库及地震、活动断裂、新生代盆地、岩浆岩分布多个专题图库；属性数据库主要针对专题图库而建立，有地震属性库、活动断裂属性库及新生代盆地属性库。通过图形数据结构和属性数据结构共有的标识码实现图形数据库和属性数据库之间的连接。为方便查询检索，对重要的属性数据如断裂走向、地震震级等以编码方式表示。该数据库的建立为定量研究和评价本区地震与新构造活动的关系，以及防震减灾提供了重要的科学依据。     

Changes in the spatial scale of Beijing UHI and urban development

The seasonal and interannual variations of Beijing urban heat island (UHI) are investigated in this paper using the temperature data from 1960 to 2000 at 20 meteorological stations in the Beijing region, and then the relationship between the intensity and spatial scale of UHI and Beijing urbanization indices is analyzed and discussed. Main conclusions are the followings. First, Beijing UHI shows obvious seasonal variations, and it is strongest in winter, next in spring and autumn, and least in summer. The seasonal variation of the UHI mainly occurs in the urban area. The UHI intensity at the center of Beijing is more than 0.8℃ in winter, and only 0.5℃ in summer. Second, the intensity of Beijing HUI exhibits a clear interannual warming trend with its mean growth rate (MGR) being 0.3088℃/10 a. The MGR of HUI is largest in winter, next in spring and autumn, and least in summer, and the urban temperature increase makes a major contribution to the growth of HUI intensity. Third, since the Reform and Opening, the urbanization indices have grown several ten times or even one hundred times, the intensity of HUI has increased dramatically, and its spatial scale also expanded distinctively along with the expansion of urban architectural complexes. Fourth, the interannual variation of urbanization indices is very similar with that of HUI intensity, and their linear correlation coefficients are significant at a more than 0.001 confidence level.     

Impact of human activity on the estuary of the Qiantang River and the reclamation of tidal flats and river regulation

The swing of the main channel of the Qiantang River is controlled by the high-water and low-water changes in the river, as well as the impact of large-scale reclamation of tidal flats. Its evolution in modern times is the result of the combined functions of natural and man-made factors. This paper analyzes the cause of the formation of the South Channel and Xisan Tidal Furrow and proposes the regulation principle of “To regulate the river and reclaim tidal flats by taking the advantage of local topography”. It is suggested to cut off the South Channel and Xisan Tidal Furrow completely to restrict the swing of the main channel and to increase the reclamation area of the tidal flat at the same time.     

The evolution of the electronics industry in Johor (Malaysia): Strategic coupling,adaptiveness, adaptation,and the role of agency

Bringing together concepts from the global production networks and evolutionary economic geography literature, this article empirically examines the trajectory of the electrical and electronics industry in Johor (Malaysia). Based on trends in firm entries and exit as well as interviews with companies, we find limited robustness in the industry’s trajectory. While there is evidence of the role of ‘structure’ in this outcome, we argue that human agency – particularly the actions of subnational policy-makers – is key. This is manifest in a preference for fostering regional ‘adaptiveness’ through the often uncritical promotion of a diversity of economic sectors. This compromises the meaningful pursuit of regional ‘adaptation’ in the form of new and more complex branches emerging from existing industries. This arrested development, in turn, hinders an effective strategic coupling between the regional economy and multinational corporations, thus undermining regional resilience.     

5—6月东北冷涡持续活动及强度特征

利用1960—2012年5—6月NCEP/NCAR逐日再分析资料,基于冷涡经典定义,采取客观识别方法检索东北冷涡活动过程,根据东北冷涡活动时空变化特征给出东北冷涡持续活动过程标准, 通过冷涡强度指数进行定量化分析,该指数对冷涡持续活动过程具有较好表征意义。冷涡活动强对应5月乌拉尔山阻塞高压、贝加尔湖阻塞高压和6月鄂霍次克海阻塞高压活动频繁。通过强弱指数年合成,得到6月强指数年冷涡系统较深厚,集中于对流层中高层,冷心结构明显,具有一定大气斜压特征; 高层存在冷中心,低层有冷空气活动,中高层西风带呈明显的上游分流和下游汇合特征,分汇流之间呈东北高、西南低的偶极子阻塞形势;弱指数年冷涡系统较浅薄,主要集中在对流层中低层,冷心结构不明显,不存在阻塞形势。
