Detailed explanation of the reasons for the interruption of the West Liao River.
The West Liao River is the largest tributary of the Liao River, and historically it is called "Huangshui", "Liaoshui" or "Da Liao River" together with the Xilamulun River, which is of great significance to the Northeast region. However, since 1998, the Xiliao River has been cut off for 25 years. The riverbed of the West Liao River also gradually shrank, eventually from 13The 60,000-square-kilometer river basin has become what it is now a "10,000-acre desert".
The reason for the interruption of the flow of the Xiliao River is due to the dual influence of natural factors and human factors. In terms of natural factors, in recent years, other rivers that flow into the Xiliao River, such as the Xilamulun River, the Laoha River, the Wulijimuren River and the Jiaolai River, have dropped sharply due to the decrease in precipitation, and their own flow has dropped significantly, at most only half of the average of the previous year. This directly reduces the amount of water flowing into the Xiliao River. In terms of human factors, the large amount of water taken from more and more barrage projects and drinking water projects is an important reason why the river water cannot be replenished in time. These projects include the growing number of "fish scale pits" water conservation project in Chifeng City, which intercepts the limited amount of rainwater from the mountain. In addition, excessive industrial and agricultural water use exacerbates water scarcity. This has caused a serious phenomenon of "water competition" in the upper and lower reaches of the Liaohe River. It can be seen that the interruption of the flow of the Xiliao River is by no means explained by a single cause.
The severe impact of the West Liao River on the local area.
The 25-year interruption has had a significant impact on the areas along the Liaohe River Basin. First, there are "three funnels" groundwater overexploitation and subsidence areas in Tongliao City, Chifeng City and Yuanbaoshan District, and the surface water level has dropped by 7-10 meters. Second, due to the interruption of the middle and upper reaches, the area of rivers, wetlands, lakes and other water systems has shrunk sharply. According to the data, the grassland area of Tongliao City has decreased by about 40,000 hectares in three years. Third, the reduction of the incoming water of the Wuli Jimulun River has reduced the self-purification capacity of the broken river, and the water quality has deteriorated to the surface water class V. The problem of water pollution has become serious to the point of "talking about pollution and discoloration".
Leads to the doubts of Songji Liao".
Faced with the predicament of the West Liao River, some people on the Internet have been calling for the state to open the "Songliao Canal" and divert the water of the Songhua River into the Liao River to solve the problem of broken flow. But this plan has also raised questions because the Songhua River itself is the largest tributary of the Heilongjiang River, and the diversion of water could reduce the amount of water in the lower reaches of the river. In addition, even if the water is diverted, it only connects the middle and lower reaches of the Liaohe River, and the help for the upstream areas where the water situation is most severe is limited.
The "Attracting Money" project releases hope.
In response to the above concerns, an important countermeasure adopted by the state is to start the project of "bringing money to Liaoning" in Inner Mongolia. The project is ready to start, and all tunnels have been opened and are expected to be completed by the end of this year. At that time, it will be possible to add 45.4 billion cubic meters of water was delivered to the upper reaches of the Liao River, greatly alleviating the water shortage in the region. Under the correct leadership, it is believed that the West Liao River, which has been cut off for 25 years, will usher in a new life.
Epilogue.
The interruption of the flow of the Xiliao River is due to multiple reasons, and it has also caused many negative impacts. The opening of the "Songliao Canal" may have its negative effects, so the current construction of the "Diversion of Liaoliao" project is full of hope. We have reason to believe that under the correct policy decisions of the party and the people, the ecological environment and people's living standards in the Xiliao River valley will certainly be greatly improved. What do you think of the future of the Xiliao River?
