“多规合一”的海洋空间规划体系设计初步研究   总被引：2，自引：0，他引：2  

王鸣岐  杨潇 《海洋通报》2017,36(6):675-681

本文分析了我国海洋空间规划中存在的矛盾,即规划内容重叠,规划部门盘根错节和空间事权分散。究其根源,在于各规划间存在技术障碍,规划体系不成熟以及缺乏与陆域规划的衔接。海洋空间规划"多规合一"的关键在于理清规划层级之间、规划主体之间、海洋空间规划与其他涉海规划之间的关系,并据此提出了"一个市县,一本规划、一张蓝图、一个平台、一套制度"的总体构想,以及目标战略融合、数据与标准融合、规划范围与规划期的融合、规划与政策融合、主体部门融合的建议。  相似文献

Summer Water Balance Characteristics of Koryto Glacier, Kamchatka Peninsula, Russia     

Takane Matsumoto  Renji Naruse  Keiko Konya  Satoru Yamaguchi  Tomomi Yamada  Yaroslav D. Muravyev 《Geografiska Annaler: Series A, Physical Geography》2004,86(2):181-190

The daily water balance for the drainage basin of Koryto Glacier, Kamchatka Peninsula, Russia, was calculated during the period from August to September 2000. The result shows that 14×10⁶ m³ of meltwater and 2×10⁶ m³ of rainwater entered the basin, while 26×10⁶ m³ of water drained from the basin through proglacial streams. Thus, about ?9×10⁶ m³ of water storage reduction occurred in the basin. Vertical displacements of the glacier surface showed that the volume change due to contraction of subglacial cavities was nearly 20% of the total storage change. The remaining fraction of water storage during the period is thought to be stored in englacial and supraglacial locations. The estimate of water balance components in the early ablation season in 2000 indicates that meltwater was already stored within the glacier before the spring, even during the previous year, and that the stored water drained through the ablation season.  相似文献   

中国附近海域地磁偏角图及其数学模式(1990.0)   总被引：2，自引：0，他引：2  

夏国辉  里弼东  张凤玉  李进杰 《测绘学报》1994,(1)

本文介绍了中国附近海域地磁偏角模式的建立和“中国邻近海区地磁偏角图”的编绘以及质量分析。在建立中国附近海区地磁偏角模式时，使用了3000多个地磁测点和地磁台站及国际参考地磁场资料，采用的方法是泰勒多项式。对海区地磁偏角模式和海区地磁图作了对比分析，其效果是好的。海区地磁偏角模式和“中国邻近海区地磁偏角图” 清楚地反映出我国南沙群岛地区尺度为1000余公里的磁异常，解决了中国地磁图和世界地磁图在这一海区未能解决的问题。海区地磁偏角模式的建立和海区地磁偏角图的绘制出版，大大地提高了我国海区及其邻近海域地磁偏角导航的精度。  相似文献   

Radon measurements as an aid to the interpretation of atmospheric monitoring     

S. Whittlestone 《Journal of Atmospheric Chemistry》1985,3(1):187-201

Radon has been measured continuously at Cape Grim, Tasmania with a detection limit of about 0.05 Bq m^-3 (1.4 pCi m^-3). The annual average level from a close continental source is 3.8 Bq m^-3, whereas the level in maritime air streams is typically 0.5 Bq m^-3. The contribution of the ocean is about 0.04 Bq m^-3, which indicates that more than 90% of radon in maritime air is from a continent. Thus radon can provide much less equivocal evidence of the degree of continental influence on an air stream than can other atmospheric constituents, whose sources and loss mechanisms are more complex. A knowledge of the past history of an air stream is important in the interpretation of atmospheric measurements.There is a close correlation between low radon and low Aitken particle concentrations, which suggests a continental origin for these particles. On the basis of present data it is difficult to reconcile this with evidence that the particles are generated photochemically over the ocean. An extension of the radon program to other latitudes would help to resolve this discrepancy.  相似文献

表碛覆盖型冰川的提取方法及变化

表碛覆盖型冰川是山地冰川的一种特殊类型,表碛的存在使得其对气候变化呈现出不同的响应特征。基于2011—2020年Landsat TM/ETM+/OLI遥感影像和ASTER DEM数据,在综合分析表碛光谱、地形和地表温度特征基础上提出TDSI（temperature NDDI slope ice）方法,并将其用于提取中国境内托木尔冰川等6条大陆型冰川和雅弄冰川等3条海洋型冰川。结果表明：基于TDSI方法提取表碛覆盖型冰川的总体精度为91.23%,其中大陆型和海洋型表碛覆盖冰川的精度分别为91.20%和90.97%。2011—2020年6条大陆型冰川和3条海洋型冰川面积平均减少0.06%和0.11%,而表碛面积分别增加了11.92%和18.35%。大陆型冰川表碛主要分布在其中值海拔以下,而海洋型冰川表碛分布范围更广,近10年间二者均呈现向冰川上部扩张趋势。气温上升是冰川消融退缩和表碛增加的主要原因,同时冰川流速变化和终碛湖演变也对表碛变化有一定影响。  相似文献   

Distancing Asylum Seekers from the State: Australia's evolving political geography of immigration and border control     

Andonea Dickson 《The Australian geographer》2015,46(4):437-454

Australia's border enforcement strategies and immigration control policies operate in distant geographies, concealed from human rights groups, media and the public. From offshore detention to militarised maritime defence operations, Australia's exclusion of asylum seekers is increasingly dependent upon geographical processes that ensure asylum seekers do not have access to the state's systems of protection. This article explores a critically overlooked geopolitical strategy of mobility regulation that relies on processes simultaneously expanding geographies of control, while contracting spaces of rights. The outcome of these rapidly evolving bordering practices is the exaggeration of the distance separating asylum seekers from the state, suspending them within a space devoid of an operational system of rights, and emphasising a new and restructured maritime legal geography.  相似文献
