Lake Landscape Tourism Resource System
Lakes are composed of water that accumulates in depressions on land. Water bodies and lake shores are important tourism resources for human activities. Based on whether a lake is connected to the sea, lakes can be classified into inland lakes and external lakes. Based on the salt content of the water, lakes can be divided into saltwater lakes and freshwater lakes. Lakes have a total area of approximately 2.0587 million square kilometres, which accounts for 1.5% of the total land area of the Earth. The total volume of lake water is approximately 176,400 km3, which is 52% of the freshwater reserves. Lakes with different formation processes, sizes, and locations and environments have formed an extensive lake landscape tourism resource system.
