2. According to the discharge situation, lakes can be divided into outflow lakes and inland lakes.
3. According to the salinity of lake water: According to the salinity of lake water, lakes can be divided into freshwater lakes (salinity less than 1g/L), saltwater lakes (salinity 1-35g/L) and salt lakes (salinity greater than 35g/L).
Main features of lakes in China.
wide distribution
Lakes in China are widely distributed, from east to west and from south to north. These lakes are not only numerous, but also varied.
Various types
The types of lakes in China include natural lakes, artificial lakes and salt lakes. Natural lakes are evolved from natural geographical environment, artificial lakes are formed by human activities, while salt lakes are formed by evaporation, resulting in high salt content in lake water.
Abundant water resources
China Lake is rich in water resources, which can not only provide domestic water, but also be used for agricultural irrigation, power generation and transportation. In addition, lakes also have the function of regulating climate, which can alleviate drought and flood disasters.
