Wudalianchi Scenic Area is mainly composed of Wudalianchi Lake Area and surrounding Volcanic Group geological landscape, related human landscape, vegetation, waterscape and so on. From 1719 to 1721, volcanoes erupted and lava blocked the Baihe River, forming five interconnected lakes, hence the name Wudalianchi. Wudalianchi Volcanic Group in Heilongjiang Province is a famous Quaternary Volcanic Group in China. It is generally believed that Wudalianchi Volcanic Group in Heilongjiang Province consists of 14 volcanoes. If it includes Lianhua Mountain in the western part of the volcanic area, Wudalianchi Volcanic Group should consist of 15 volcanoes, with an area of more than 800 square kilometers. The formation of Wudalianchi Volcanic Group has a history of nearly 700,000 years. It is known as the "Volcanic Museum" and has become the first volcanic Nature Reserve in China.
