Under the macroscopical background of "Polar Silk Route", the paper puts forward the land and river intermodal transport route from Dalian to Tiksi Port of the Arctic Ocean (hereinafter referred as land and river intermodal transport route). The land and river intermodal transport route is a line available, which vertically connects the two economic belts between the northeast of China and the Siberia of Russia. Through the comprehensive analysis of the latest researches upon river and land intermodal transport route, which are carried out by Heilongjiang University, Melnikov Permafrost Institute of Russian Academy of Sciences and North-Eastern Federal University. Among them, the river transport section is the waterway from Russian Yakutsk City to Lena River of Tiksi Port; the land transport section runs through China and Russia and the central part of Northeast Asia, mainly including the railway and highway transport from Dalian to Yakutsk. And the main cities along the river and land intermodal transport route contain: China Dalian-Harbin-Heihe-Russian Blagoveshchensk (Hailanpao)-Neryungri-Yakutsk-Tiksi Port. Every node of land transport section has mature transportation systems, transit nodes with complete facilities and great economic development prospects. From July to September, Lena River has at least 3 months suitable for shipment and allows ship navigation with a weight of over 3000 tons. In summer, the Sino-Russia Northeast Asia land and river intermodal transport route has advantages of both short transportation distance and time. Along the route, there are abundant mineral resources. When the economy along the route gets improved, the trades between Asia and Europe can be connected and enhanced.
