Why does Tongliao hang sand?

The reason why Tongliao hangs sand is influenced by drought and sandstorm. Tongliao is located in the arid and semi-arid area of northern China, with dry climate, less rainfall and easy drying and weathering of the land. At the same time, overgrazing and reclamation of grasslands around Tongliao led to land degradation and desertification.

In order to solve the problem of suspended sediment in Tongliao, the following measures can be taken:

1. Strengthen land protection and governance. Strengthen grassland protection and management, avoid overgrazing and reclamation, strengthen water and fertilizer measures to prevent land degradation and desertification.

2. Promote the utilization of water resources. Strengthen the development and utilization of water resources, popularize water-saving irrigation technology, improve agricultural water use efficiency, reduce land moisture evaporation and loss, and avoid land drying and weathering.

3. Strengthen environmental monitoring and early warning. Strengthen environmental monitoring and early warning, find the trend of land degradation and desertification in time, and take effective measures to contain and control it.

4. Strengthen scientific and technological support. Strengthen the research and application of science and technology, develop new technologies for drought and sand prevention and ecological restoration, and improve land quality and productivity.

To sum up, there are many reasons for sand hanging in Tongliao, and various measures need to be taken to control and prevent it. Strengthening land protection and management, popularizing water resources utilization, strengthening environmental monitoring and early warning, and strengthening scientific and technological support are effective ways to solve the suspended sediment problem in Tongliao.
