How to control the interruption of the Yellow River, the reasons and measures for the interruption o

Plant trees and grasses to increase vegetation cover.

There are many reasons for the interruption of the flow, which can be summarized as follows:

Global warming. With the intensification of global warming in recent years, on the one hand, the evaporation of the river channel has increased greatly, and on the other hand, the melting of the upper glaciers in spring and summer absorbs a large amount of heat, resulting in lower than usual local temperatures in the interior, which reduces the temperature difference between the inland and the ocean, and then causes the monsoon to weaken, and the lack of water vapor brought by the monsoon from the sea surface to the inland. Although the melting of glaciers due to global warming has increased the flow of water upstream, it has not offset the effects of increased evaporation and weakening of the monsoon.

As a result, the amount of water in the middle and lower reaches is decreasing year by year.

Destruction of vegetation. The vegetation in the Loess Plateau is seriously damaged, the land lacking vegetation conservation is gradually desertified, the evaporation becomes higher, and the dry groundwater needs to be continuously absorbed and flowed through the river to replenish.

Irrigation methods are backward. Most of the middle and upper reaches of the Yellow River are economically underdeveloped and marginal and poor areas, lacking water-saving irrigation technology and funds, and most of them are flooded, and the Yellow River is seriously wasted.

Measures: planting forests and grasses, greening the earth, and improving the local climate Planting forests and grasses, expanding vegetation coverage, developing ecological economy, combining resource development with soil and water conservation, conserving water sources, conserving water and soil, preventing soil erosion, improving local climate, reducing flood hazards, increasing soil fertility, and increasing underground runoff.

Control the number of the population and improve the quality of the population.

What are the main reasons for the Yellow River to break its flow?

Analysis of the causes of the Yellow River disconnection: The reasons for the formation of the Yellow River disconnection can be summarized into two aspects: first, natural factors; The second is human influence, and the specific analysis has the following points:

1 Water resources are scarce and unevenly distributed in time and space.

2 Precipitation is on the low side.

3 The water used to divert water from the Yellow River in agriculture has increased rapidly.

4. The development and utilization of water resources in the Yellow River is seriously wasted.

5. The reservoir regulation capacity is low, and the management and scheduling are not uniform.

From the above-mentioned reasons for the interruption of the flow, it can be seen that in order to solve the problem of the interruption of the flow of the Yellow River, the focus is to solve the contradiction of less water and more water in the dry season, and its principles are fourfold: first, increase the amount of water flow; the second is to reduce water consumption; the third is to adjust the time of water use; Fourth, strengthen the protection of water quality.

Specific measures to cut off the flow of rivers.

strengthen the unified allocation and management of water resources in the whole basin;

planting forests and grasses in the basin to green the land and improve the local climate;

Adjust the agricultural structure in the basin and reduce water consumption Vigorously cultivate and promote drought-tolerant crops in the basin to reduce irrigation water consumption;

the development of water-saving agriculture;

Transfer water across river basins to replenish it.

Natural causes: the seasonal distribution of precipitation in the Yellow River Basin is uneven, with less precipitation in winter and spring, and less water entering the river; The lower reaches of the Yellow River are above-ground rivers with no tributaries and almost no groundwater replenishment. The north is dry and windy, and the evaporation is large. Human causes:

The upper and middle reaches of the coastal areas take a lot of water, so that the amount of water flowing into the downstream is very small. The main natural causes are:1

Most of the Yellow River Basin has an arid and semi-arid continental climate, with uneven distribution of annual precipitation, with heavy rainfall in summer and scarce precipitation in winter. As a result, the annual runoff of the Yellow River varies greatly, and the phenomenon of flow interruption often occurs. 2.

The Yellow River has a large sediment content and silt accumulation, forming an above-ground river in the lower reaches, which destroys the complementary mechanism of river water and diving, so that the Yellow River cannot be replenished by diving on both banks, but has been replenished by diving. 3.Global warming this year has made precipitation even scarcer in the already arid Yellow River basin, and the Yellow River's water supply is insufficient.

The main human reasons are:1Long-term deforestation has seriously reduced the vegetation cover in the Yellow River Basin, and the water storage and retention capacity of the land has decreased.

2.With the rapid development of the city, the water used for domestic and industrial use in the city has increased dramatically, coupled with the waste of water, resulting in a serious reduction in the water resources of the Yellow River. 3.

Agricultural irrigation methods in the Yellow River Basin have not been improved, with large water consumption and low water resource utilization. 4.The heavy use of fossil fuels exacerbates the greenhouse effect, leading to a continued warming climate.

The natural interruption of the Yellow River began in 1972, mainly in the downstream Shandong section, and in the 25 years from 1972 to 1996, there were 19 years of dry interruption, with an average of three times in four years.

After 1987, there was a continuous flow interruption almost every year, and the interruption time was continuously advanced, the scope of the interruption continued to expand, and the frequency and duration of the interruption continued to increase.

In 1995, the Lijin Hydrological Station, located in the estuary section, lasted for 122 days, and the length of the broken river extended to the vicinity of Chenqiao Village below Kaifeng City, Henan Province, with a length of 683 km, accounting for more than 80% of the length of the river in the lower reaches of the Yellow River (below Huayuankou).

In 1996, the Luokou Hydrological Station, located on the outskirts of Jinan, began to run off on February 14. The Lijin Hydrological Station was cut off seven times that year, lasting 136 days. In 1997, the interruption lasted for 226 days, which was the longest interruption.

Analysis of the reasons for the interruption of the Yellow River:

1 Water resources are scarce and unevenly distributed in time and space.

2 Precipitation is on the low side.

3. The rapid increase in water use for the diversion of yellow industry and agriculture along the Yellow River;

4. The development and utilization of water resources in the Yellow River is seriously wasted.

5. The reservoir regulation capacity is low, and the management and scheduling are not uniform.
