新華社呼和浩特4月12日電（記者王春燕、連振）位於東北地區的西遼河幹流在斷流27年後，10日實現全線過流。這件西遼河兩岸群眾奔相告的“大喜事”，值得上一次“熱搜”。

Compared with the Yangtze River, the Yellow River and other major rivers, the West Liao River is not well-known. But when it comes to Xinglongwa culture and Hongshan culture, and when it comes to the Horqin Sandy Annihilation War, you think of "the granary of Inner Mongolia" and "the hometown of Chinese cattle...... These are closely related to the Xiliao River.

This large river, which originally rushed between the valley and the grassland, has suffered a "catastrophe" in the past 1998 years. Since 0 years, with the decrease of rainfall in the West Liao River Basin and the expansion of agricultural production, the main stream of the West Liao River has been cut off all year round, and the ecology of the West Liao River Basin has been in danger.

In 10 years, the Ministry of Water Resources carried out a unified dispatch of water resources in the West Liao River Basin, and the main stream water head was extended downstream every year, and finally the whole line was overflowed on 0 0 this year.

-- This is a "great joy" for the people on both sides of the Xiliao River.

The Xiliao River has been flowing all year round, so that the concept of "river" has disappeared from many people's lives, and many rivers have become cultivated land, and the original outline of the wheel has gradually blurred.

  今年3月以來，圍觀西遼河水頭成了當地不少群眾的每日功課，不少網路主播乾脆開著直播追著水頭走。

"River overflow can effectively replenish the ecological water volume of the river, improve the ecological environment of the river, and promote the restoration of aquatic biodiversity, which is of great significance to alleviate the ecological problems such as river breakage, groundwater overexploitation, and grassland desertification." Yang Zhaowu, deputy director of the Water Affairs Bureau of the Left Wing Central Banner of Horqin, Tongliao City, said.

-- This is a "shot in the arm" for ecological governance.

  西遼河不僅是沿岸百姓的母親河，它流經的區域也是科爾沁沙地殲滅戰的主戰場。科爾沁沙地橫跨內蒙古、吉林、遼寧三省區，沙地面積達7760萬畝，在內蒙古通遼市境內佔52.7%。

Regarding the flow of the main stream of the West Liao River, Chao Ketu, head of the forestry workstation of the Left Wing Rear Banner of Horqin, Tongliao City, said: "This is a good sign! In the view of this sand control expert, who has been fighting against sand for more than 30 years, effective ecological management can curb the trend of land desertification and improve the ability of sandy land to conserve water.

  這也是朝克吐在過去30多年反覆驗證過的道理，因為科爾沁左翼後旗千余萬畝沙地中現在分佈著500多個大大小小的湖泊濕地。在10年前，這裡的湖泊濕地還只有30多個。

Migratory birds such as swans and geese with high requirements for the quality of the ecological environment have returned one after another, and the vitality of the river basin has gradually recovered and rejuvenated.

——This is a river to explore Chinese civilization.

The Xiliao River Plain has given birth to a brilliant human civilization in the basin.

Xiaohexi Culture, Xinglongwa Culture, Zhaobaogou Culture, Hongshan Culture, Xiaoheyan Culture, Xiajiadian Lower Culture, the places where these cultural forms are found and named are all in the West Liaohe River Basin. The long river of history rolls forward, connecting the past and present of this land.

Looking at the clear water of the West Liao River, Zhang Tienan, a professor at Inner Mongolia University for Nationalities, who has been deeply involved in the culture of the West Liao River all year round, said: "The West Liao River is a natural river, nourishing the grass and trees along the river; It is also a river of culture, inheriting the cultural genes of generations of people. ”
