Measures against landslides in the valleys of the Lanzhou section of the Yellow River

Measures against landslides in the valleys of the Lanzhou section of the Yellow River include.

1. Unified planning and comprehensive management. The recommended comprehensive management plan mainly includes slope reduction and unloading engineering, slope surface improvement engineering, anti-slip engineering, improving drainage facilities, planting grass and trees, biological engineering and avoidance engineering. bypass countermeasures. It is recommended that relevant departments make unified plans based on the degree of risk of the disaster and gradually implement comprehensive management projects.

2. Disaster management and urban development and construction proceed simultaneously. With the rapid development of economic construction, many slope areas and even valleys have been expanded into urban construction land, which has induced a large number of landslides along mountain slopes and valley areas. Comprehensive assessment of environmental geology should be strengthened to carry out simultaneous and comprehensive management to ensure the safety of newly built economic development zones and residential areas.

3. Improve policies and regulations and strengthen implementation. In 1987, the Lanzhou Municipal Construction Committee issued the "Interim Regulations on the Prevention and Control of Weipo (Collapse) in the North and South Mountains of Lanzhou City", which played a positive role in disaster prevention and reduction. On this basis, the "Regulations" should be further improved to restrict various unreasonable human activities in the form of laws and regulations, strictly prohibit unplanned and unapproved digging and construction, protect the ecological environment and prevent landslide disasters.

4. Carry out monitoring and forecasting to enhance the public's awareness of disaster prevention, and establish a landslide early warning system in Lanzhou City to carry out monitoring and forecasting work for important factories and mines, transportation trunk lines, economic development zones, and residential areas with landslide dangers. At the same time, we will adopt certain forms to publicize the basic knowledge of landslides to the masses, enhance the public's awareness of disaster prevention and reduction, and protect the natural environment, reduce artificial excavation of slope footings and random discharge of wastewater, and consciously protect the ecological environment of Lanzhou City to reduce landslide disasters. .
