短信息——浙江省将建成海洋特别保护区     

《海洋世界》2006,(6):5-5

据浙江省政府办公厅披露，省政府日前颁布了《浙江省海洋特别保护区管理暂行办法》，明确指出，七类区域将可以设立海洋特别保护区。一旦保护区设立，将严禁从事狩猎、电鱼等行为。浙江省提出，海洋特别保护区可以开展旅游活动，但要科学确定旅游区的游客容量，合力控制游客流量，建立协调的生态经济模式。浙江是全国海岛数量最多、海岸线最长的省（市）。据悉，象山港、岱山、嵊泗、普陀、大陈岛等区域有望不久跻身浙江首批海洋特别保护区。  相似文献   

STUDY ON DEVELOPMENT STRATEGY OF SHIPPING CENTERS AND TRANSPORTATION NETWORKS IN THE YELLOW SEA RIM IN THE YELLOW SEA RIM     

JINFeng-jun 《中国地理科学(英文版)》2003,13(2):97-103

It is very important to establish cooperative mechanism to guarantee all members to develop their e-conomies in the Yellow Sea Rim. In this paper, the development strategies ofshipplng centers and transportation networkare discussed based on economic giobalization tendency. The results argue that a united transportation network should bebuilt in order to promote the economic competition of Northeast Asia in the world. As a key component of the economiccooperation, a hierarchical shipping centers network should be established with Hong Kong, Shanghai, Pusan, Koho,and Tokyo as cores. The authorities of China, Japan, R. O. Korea and D. P. B. Korea should make more efforts tobuild a set of cooperation institutions based on raising the transportation efficiency.  相似文献

太平洋命名的历史     

方陵生 《海洋世界》2006,(11):36-39

在一个风帆远航为海上最快速交通工具的时代里,大陆和海洋向着不可知的远方延伸着,人类显然无法测定各大海域的界限。在一些有关混沌初开的神话传说里,人类深感大海的浩渺辽阔,以人类自身的渺小,如何给这片无边无际的永恒大海命名呢?  相似文献

Pco2 of air and seawater samples from the East China Sea(ECS) were measured in situ in autumn, 1994,Ocean currents,terrestrial fluviation,biological activities,etc.,Pco2 char-acters in air and seawater were investigated,CO2 flux and its character in the East China Sea are discussed on the basis of the Pco2 profiles of air and seawater,It was clear that the nearshore was the source of CO2;and tht the oulter sea area was the sink of CO2; and that the shelf area of the EXS is a net sink for atmospheric CO2 in autumn.  相似文献

严豪健郭鹏  张贵霞黄珹 《中国科学院上海天文台年刊》2003,(24):39-47

简要地介绍了GPS／LEO卫星无线电掩星技术的基本原理、意义以及国际上的最近动态，列举了几个主要的LEO卫星计划；重点分析了GPS掩星探测地球大气技术中需要注意的若干问题，并推出可能采取的改进方案和相应的技术路线。上海天台在GPS／LEO空基气象学中已经成功地提出：通过通约LEO／GPS轨道方法，实现掩星地面观测点控制的新思路。作为一个应用实例，针对东中国海洋上空大气状况对中国东部经济发达的地区特别是上海地区的天气有着重要影响的背景，提出利用通约LEO／GPS卫星可对该地区大气实施监控。为了充分利用GPS／LEO掩星观测资源，上海天台开展了振幅反演的计算方法研究；提出了在振幅反演中存在着无线电信号几何衰减和物理衰减两种不同的衰减机制，并考虑了它们的数学模型以及对反演结果的影响。简要地叙述了掩星质量因子的定义和计算方法。作为国内天地球动力学研究中心，上海天台将与国内外一些合作单位考虑建立GPS／LEO掩星技术观测处理的软件系统。作为空基GPS气象学的推广，还考虑进行山基和飞机载掩星观测实验，论证用这些方法监测局部大气剖面的可行性以及它们在国民经济和科学研究上的作用。  相似文献

Silicon limitation on primary production and its destiny in Jiaozhou Bay, China——Ⅳ：Study on cross-bay transect from estuary to ocean   总被引：1，自引：0，他引：1

The authors analyzed the data collected in the Ecological Station Jiaozhou Bay from May 1991 to November 1994, including 12 seasonal investigations, to determine the characteristics, dynamic cycles and variation trends of the silicate in the bay. The results indicated that the rivers around Jiaozhou Bay provided abundant supply of silicate to the bay. The silicate concentration there depended on river flow variation. The horizontal variation of silicate concentration on the transect showed that the silicate concentration decreased with distance from shorelines. The vertical variation of it showed that silicate sank and deposited on the sea bottom by phytoplankton uptake and death, and zooplankton excretion. In this way, silicon would endlessly be transferred from terrestrial sources to the sea bottom. The silicon took up by phytoplankton and by other biogeochemical processes led to insufficient silicon supply for phytoplankton growth. In this paper, a 2D dynamic model of river flow versus silicate concentration was established by which silicate concentrations of 0.028–0.062 μmol/L in seawater was yielded by inputting certain seasonal unit river flows (m³/s), or in other words, the silicate supply rate; and when the unit river flow was set to zero, meaning no river input, the silicate concentrations were between 0.05–0.69 μmol/L in the bay. In terms of the silicate supply rate, Jiaozhou Bay was divided into three parts. The division shows a given river flow could generate several different silicon levels in corresponding regions, so as to the silicon-limitation levels to the phytoplankton in these regions. Another dynamic model of river flow versus primary production was set up by which the phytoplankton primary production of 5.21–15.55 (mgC/m²·d)/(m³/s) were obtained in our case at unit river flow values via silicate concentration or primary production conversion rate. Similarly, the values of primary production of 121.98–195.33 (mgC/m²·d) were achieved at zero unit river flow condition. A primary production conversion rate reflects the sensitivity to silicon depletion so as to different phytoplankton primary production and silicon requirements by different phytoplankton assemblages in different marine areas. In addition, the authors differentiated two equations (Eqs. 1 and 2) in the models to obtain the river flow variation that determines the silicate concentration variation, and in turn, the variation of primary production. These results proved further that nutrient silicon is a limiting factor for phytoplankton growth. This study was funded by NSFC (No. 40036010), and the Director's Fund of the Beihai Sea Monitoring Center, the State Oceanic Administration.  相似文献
