中俄边界发生重大变化已150余年,探寻中俄边界发生变化的主要原因时,不能不提及Г.И.涅维尔斯科伊。他提出并探明阿穆尔河下游能行驶海船,并将设想付诸行动。涅维尔斯科伊通过考察证明萨哈林岛屿和大陆之间存在着一海峡,阿穆尔河口湾可以通航,此外除几个基里亚克小村外,在此既无中国驻军,亦无堡垒和军舰。涅维尔斯科伊的考察行动暴露出我国边防空虚、地方行政鞭长莫及、边民较少以及交通困难之窘境。 After more than 150 years of major changes in the Sino-Russian border, the main reason for the change in the Sino-Russian border can not but be referred to as Г.И Neielskoye. He proposed and proved that the lower reaches of the Amur River can travel sea ships, and put the idea into action. Niewerskoy verified that there was a strait between the island of Sakhalin and the mainland and that the Amur estuary was navigable. In addition to the small villages of Kiriac, neither the Chinese garrison nor the fort and warships . The inspection by Niewerskoy reveals the dilemma of our country’s border guerrillas, their lackluster local administration, their trivialization of border people and the difficulty of transportation.
