The Loess Plateau is a key area for soil erosion control in China in recent years. On the 4th, the China Meteorological Administration released the "2022 National Ecological Meteorological Bulletin" in Beijing, which showed that the overall ecological quality of vegetation in China was good. From 2000 to 2022, 91.9% of the regional vegetation ecological quality index showed an upward trend, especially in the Yellow River Basin. Among them, 79.1% of the regions had an average annual increase of more than 2.5 grams of carbon per square meter in net primary productivity of vegetation, and the area with an increasing trend of vegetation coverage in the basin reached 96.4% of the total basin area, indicating significant improvement in vegetation ecology. In 2022, the national vegetation ecological quality index was 68.3, an increase of 6.2% compared to usual, and the third highest since 2000.

"Specifically, the improvement of vegetation ecological quality in the Yellow River Basin has enhanced soil and water conservation capacity, with 87.6% of regional water conservation and 98.7% of regional soil conservation showing an increasing trend. Due to the improvement of vegetation ecology, the function of wind and sand fixation has been enhanced, and sand and dust weather has significantly decreased. From a meteorological perspective, since 2000, the precipitation in the Yellow River Basin has shown an overall increasing trend, with an average annual increase of 4.2 millimeters in precipitation and a temperature increase of 0.03 ℃. Water and thermal conditions are more favorable for the growth of vegetation in the basin. Among them, the average annual increase in precipitation in the Yellow River Delta from 2000 to 2022 was 13 millimeters, and the temperature increased by 0.05 ℃. Monitoring results show that vegetation coverage along the Yellow River main and tributaries and its surrounding areas has significantly increased, and the ecological environment has significantly improved." Qian Shuan, a senior engineer at the research level, pointed out that there are two main reasons for the overall improvement of vegetation ecological quality in the Yellow River Basin and other parts of the country. Firstly, the country attaches great importance to ecological civilization construction and has implemented a series of ecological protection and repair projects; The second is the combination of favorable meteorological conditions, which together promote the improvement of national vegetation ecological quality.

Qian Shuan introduced that, considering the impact of climate change on glaciers, the bulletin has added an impact assessment of typical glaciers in the Three Rivers Source - the Animaqing Snow Mountain Glacier and the Geladan Winter Glacier. The results show that since 2000, the glacier area of Animaqing Snow Mountain has decreased by an average of 0.67 square kilometers per year, and the ice storage has decreased by an average of 0.06 cubic kilometers per year; The winter glacier area and ice storage in various Ladan regions are also showing a decreasing trend, with an average annual decrease of 2.73 square kilometers in glacier area and 0.32 cubic kilometers in ice storage. This indicates that since 2000, the temperature and precipitation in the Three River Source region have increased, which is beneficial for vegetation growth and lake water storage. However, the temperature increase has promoted the melting of ice and snow and glacier shrinkage.

Currently, the highly anticipated summer harvest work in Henan has shifted its focus to the northern region of Henan. According to the Henan Daily client, on June 4th, Lou Yangsheng, Secretary of the Henan Provincial Party Committee, presided over a special video scheduling meeting on the "Three Summers" work in the province, listened to the situation report, analyzed and judged the situation, and arranged and deployed the next steps of work. Governor Wang Kai made specific arrangements. On the evening of May 31, 2023, in Xiafutou Village, Xuliang Town, Boai County, Jiaozuo, Henan Province, villagers braved light rain in the wheat fields to harvest wheat. Visual China Map Lou Yangsheng pointed out that the current summer harvest battle in the province has entered the decisive stage. Doing a good job in summer harvest in northern Henan Province is related to the summer grain yield and seed safety. We should focus on seizing opportunities and make every effort to organize the wheat harvesting work in the northern Henan region, minimize losses, and protect the interests of farmers to the greatest extent possible. Accurate forecasting is essential

On June 4th, the return capsule of the Shenzhou-15 manned spacecraft successfully landed at the Dongfeng landing site. Astronauts Fei Junlong, Deng Qingming, and Zhang Lu all safely and smoothly exited the spacecraft, and the Shenzhou-15 manned flight mission was a complete success. What innovative technologies are there to safeguard the return journey of Shenzhou 15 in this mission? On June 4th, the return capsule of the Shenzhou-15 manned spacecraft successfully landed at the Dongfeng landing site. Xinhua News Agency reporter Lian Zhen photographed that "the sky and the ground" ensure the high-precision return of spacecraft. For the Shenzhou series spacecraft, the return and re-entry GNC technology is directly related to the life safety of astronauts.

On the evening of June 1st, the US Senate passed a bill on the federal government's debt ceiling and budget, and the flame of the US debt bomb was temporarily extinguished at the last moment. The two parties in the United States have staged an extreme tug of war over the US debt bomb. Some experts believe that the US debt crisis is the result of the reckless politics promoted by the US dollar hegemony, and the underlying cause of this crisis is the highly polarized political system of the US. Since the end of World War II, the US Congress has adjusted the debt ceiling more than a hundred times. The recurring debt crisis will not only have a catastrophic impact on the US economy and people's livelihoods, but also continuously erode the value of US dollar assets such as government credit and US bonds, bringing significant and far-reaching impacts to the global economic landscape. 【
