【摘要】：北極地區(qū)由于長年有浮冰覆蓋,又極其寒冷,環(huán)境惡劣,致使一直無法正常通航。近年來,隨著北極地區(qū)受全球環(huán)境變化影響,冰層逐漸融化,這從客觀方面為商船通往北極海域提供了可能。從東北亞到達歐洲的航線中,北極東北航道相比蘇伊士運河航線有著眾多優(yōu)勢,不僅可以在航程上縮短30%,而且可以擺脫索馬里海盜和印度洋海盜的威脅。海冰是影響北極東北航道通航與否的關(guān)鍵因素,隨著北極東北航道的進一步開通,經(jīng)由東北航道的商業(yè)活動也越來越頻繁,加強對北極東北航道的冰情進行分析,不僅可以提升船舶航行的安全性,還可以將航運利益最大化。本文利用德國不萊梅大學2006-2015十年間的海冰密集度產(chǎn)品,以"永盛"輪首航北極東北航道時所經(jīng)航線為例,提取了北極東北航道的冰情要素,包括:航線通航窗口、逐日海冰密集度時空分布以及海冰密集度月標準差等。根據(jù)航線冰情要素分別得出了:十年間航線通航窗口的基本情況;十年間航線所經(jīng)水域的大體通航情況和主要冰障位置;7-10月份航線所經(jīng)水域海冰密集度的變化動態(tài)。通過對航線冰情要素的分析,得出影響北極東北航道的兩個關(guān)鍵海域,包括:自東西伯利亞海中部沿航線向西,至新西伯利亞群島東部海域(定義為A航段);自拉普捷夫海中部(120° E)沿航線向西,經(jīng)過維利基茨基海峽,至謝爾蓋·基洛夫群島水域(定義為B航段)。兩個關(guān)鍵水域中,對"永盛"輪航線的通航與否起決定性作用的為B航段。本文對"永盛"輪航線以及兩個關(guān)鍵水域的航線通航窗口的變化趨勢進行了分析,結(jié)果表明:"永盛"輪航線的實際通航期和B航段的實際通航期呈上升趨勢,并且均通過了 90%的顯著性檢驗,說明實際通航期的上升趨勢比較明顯。通過對"永盛"航線冰情要素的分析,發(fā)現(xiàn)該分析結(jié)果可以較好的反應出北極東北航道的實際通航情況,具有可行性。為北極東北航道通航條件研究提供了新的思路與方法。
[Abstract]:The Arctic has been unable to navigate normally because of its long ice cover, extreme cold and harsh conditions.In recent years, as the Arctic region is affected by global environmental changes, the ice gradually melts, which objectively makes it possible for merchant ships to reach the Arctic waters.In the route from Northeast Asia to Europe, the Northeast Arctic Passage has many advantages over the Suez Canal route. It can not only shorten the voyage by 30 percent, but also get rid of the threat of Somali pirates and Indian Ocean pirates.Sea ice is a key factor affecting the navigation of the North East Passage. With the further opening of the North East Passage, commercial activities through the Northeast Passage are becoming more and more frequent, so we should strengthen the analysis of the ice situation in the North East Passage.It can not only enhance the safety of navigation, but also maximize the benefits of shipping.In this paper, using the ice intensity products of Bremen University in Germany from 2006 to 2015, and taking the route of the first voyage of the North East Passage of the "Insein" as an example, the ice condition elements of the Northeast Passage of the Arctic are extracted, including the navigation window of the route.The spatial and temporal distribution of sea ice concentration and the monthly standard deviation of sea ice concentration.According to the ice condition elements of the route, the basic conditions of the navigation window in the past ten years, the general navigation situation of the waters through which the route passes during the decade, and the variation of sea ice density in the main ice barrier positions in July and October are obtained respectively.Based on the analysis of the ice condition elements of the route, it is concluded that two key sea areas affecting the North East Passage of the Arctic are: from the central part of the East Siberian Sea to the west along the route,To the eastern sea area of Novosibirsk Islands (defined as section A; from the central part of the Laptev Sea, 120 擄E) along the route westward, through the Strait of Vili Kitzki and to the waters of Sergei Killov Islands (defined as Section B).Among the two key waters, section B plays a decisive role in the navigation of the "Insein" course.In this paper, the changing trend of the navigation window of the "Yongsheng" and two key waters is analyzed. The results show that the actual navigation period of the "Yongsheng" and section B is on the rise.All of them have passed 90% significant test, which shows that the rising trend of actual navigation period is obvious.Through the analysis of the ice condition elements of the "Yongsheng" route, it is found that the result of the analysis can reflect the actual navigation situation of the North East Passage, and it is feasible.It provides a new way of thinking and method for the study of the navigation conditions of the North East Passage.
