未来五年,中国将在沿海经济增长的三“极”——长江三角洲,珠江三角洲和渤海湾区域,建设三大港口群,着重发展大型的集约化和专业化码头,为经济增长、对外开放和区域经济腾飞提供坚实的物质基础。交通部规划司副司长任建华说,依据国务院刚刚原则通过的港口群建设规划,到2010年这三大港口群的吞吐能力将至少增加一倍,达到35亿吨,从而构筑三条顺畅的综合运输海上通道。 相似文献

我国铁矿石码头布局展望 总被引:1,自引:0,他引:1
近几年来,我国港口结构性矛盾突出,铁路和公路集疏运系统能力紧张,与港口难以配套,使铁矿石大量压港。“十一五”期间,长江三角洲及长江流域将形成以宁波一舟山港和连云港港为主的矿石接卸转运基地。长江以北地区天津、青岛、大连等继续作为铁矿石中转码头发挥作用,随着曹妃甸铁矿石码头的竣工,将缓解长江以北地区的铁矿石压港情况。并加大东南沿海和珠江三角洲地区的铁矿石码头建设,重点建设福州和广州等港口。 相似文献

阐述我国集装箱码头2011年生产建设情况,分析我国集装箱码头设计通过能力利用率和单位码头岸线资源利用情况,认为我国港口集装箱码头能力小于实际吞吐量需求,缺口约为2230万TEU。提出未来我国集装箱码头仍需继续建设,但要有规划和重点,环渤海、长江三角洲和珠江三角洲等3个地区集装箱码头要通过升级改造和新建等方式来解决能力不足的问题;东南沿海、西南沿海和长江流域的集装箱码头的能力则稍为过剩,码头建设需认真规划和谨慎对待等建议。 相似文献

The hydrophysical and hydrochemical structure of the Sea of Azov, with developed bottom anoxia, was studied during the RV “Akvanavt” cruise from July 31 to August 03, 2001. The anoxic zone with a thickness from 0.5 to 4 m above the bottom was found in all deep regions of the Sea. Concentrations of hydrochemical parameters were similar to the pronounced anoxic conditions (about 90 mmol m− 3 of hydrogen sulfide, 17 mmol m− 3 of ammonia, 6 mmol m− 3 of phosphate, 7 mmol m− 3 of total manganese). The hydrophysical structure was characterized by the uniform distribution of temperature in the upper 6–7 m mixed layer (UML). Below this a thin (0.4–0.8 m) thermocline layer was observed, just above the anoxic waters. Formation of this phenomenon was connected with that summer weather conditions. Intensive rains led to increased influx of river waters in June. That resulted in large input of allochtonous organic matter (OM) and inorganic nutrients; the latter were consumed on the additional autochthonous organic matter production. In July the weather was characterized by a significant rise in the daily averaged air temperature and large oscillations of temperature during the day. In this period a wind of constant direction was absent, but wind bursts were observed. The completed analyses showed that the formation of such a structure could be connected with the following factors: (i) positive growth trends of the daily averaged temperature and the daily oscillations of temperature, (ii) presence of wind bursts. The joint action of these factors resulted in the formation of the UML. The amplitude of wind bursts determined the depth of UML, and the value of trend determined the value of the temperature change in the thermocline. An initial presence of bottom halocline (caused by the Black Sea water influx to the bottom of the Sea of Azov) prevented the heating of the bottom layer and therefore led to an increase of vertical gradient of temperature in the thermocline. The spatial distribution of the turbulent exchange coefficient confirmed the existence of a “stagnation” area located above the anoxia zone, which is also, apparently, the reason for its occurrence. 相似文献
