水利部:华北地下水超采治理取得明显成效_我的网站

假面骑士空我

A |     A sizable piece of trash discovered in the middle of a sheep pasture in Eastern Australia's New South Wales may be space debris from a SpaceX mission and connected to a loud blast reported in early July in the area, Australian ABC News has reported.,According to the report, numerous people who heard the sound on July 9 turned to social media to report it from as far away as Albury, Wagga Wagga, and Canberra to the Snowy Mountains in southern New South Wales.,An extraordinary nearly three-meter-high object was reported by farmer Mick Miners, who runs a sheep farm at the remote area of Numbla Vale.,"I didn't know what to think, I had no idea what it was," he told the outlet, while his neighbor, Jock Wallace, who also stumbled upon strange debris said he "didn't hear the bang, but my daughters said it was very loud. I think it's a concern it's just fallen out of the sky. If it landed on your house it would make a hell of a mess.",As we all wait for the Chinese booster to impact-Here’s some photos of pieces believed to be from SpaceX’s Crew-1’s Trunk, which landed in Australia on July 9th, but discovered in farmland on July 25thThese are large pieces; which could be dangerous & fatal & more frequent. pic.twitter.com/ImaO4YKQzL— Earth Consuming Mike (@LCS_Big_Mike) July 29, 2022,Serial numbers were seen on one of the items discovered on his premises. Astrophysicist Brad Tucker from the Australian National University College of Science reportedly claimed that the debris was most likely from the craft's unpressurized crew trunk.,SpaceX's Crew Dragon Lifts Off for Its First Operational Mission to ISS16 November 2020, 00:29 GMT,He said that it might be the biggest piece of debris to have been found in Australia since NASA's Skylab space station crashed to Earth above Esperance, Western Australia, in 1979.,"In photographs of the debris you can clearly see charring, which you would expect from re-entry," Tucker told the outlet last Friday. "It is very rare to see, because they don't usually land on land, but in the ocean.",I just got back from Dalgety, NSW. I was busy confirming that parts of a @SpaceX Crew-1 Trunk capsule crashed into a few paddocks in rural NSW!

According to the expert, the craft was probably traveling at 25,000 kilometers per hour when it made re-entry and left behind debris, and it was probably responsible for the July 9 blast heard by many people in the area.,This Monday, in an interview on a local radio, quoted by the Daily Mail, Tucker confirmed that the debris belonged to the Crew-1 SpaceX mission spacecraft.,"This is most definitely space junk which was part of the SpaceX Crew-1 trunk," he is quoted as saying. "SpaceX has this capsule that takes humans into space but there is a bottom part... so when the astronauts come back, they leave the bottom part in space before the capsule lands.",The component, most likely made of aluminum and carbon composites, has been in orbit since November 2020, according to the expert.,"There was a plan of having it come down on Earth and purposely hitting the Earth's atmosphere so it would break apart and land in the ocean," he said.,It took some time to find the object, according to Tucker, because it had fallen far from Miners' house.,"From a distance it looks like a tree almost, like a burnt tree, and then you get closer and you realise 'hey that's not right'," Tucker explained.。    

中新网9月13日电 针对华北地下水的超采问题,水利部部长李国英13日回应称,通过“节、控、换、补、管”五项措施,这几年华北地下水超采治理取得了明显成效。从地表的河流和湖泊来看,永定河恢复了过流、潮白河恢复了过流、滹沱河恢复了过流,白洋淀重现生机,断流干涸了将近一百年的京杭大运河黄河以北段今年也实现了全线过流贯通,实现了与永定河的百年交汇。

B | 中宣部13日举行“中国这十年”系列主题新闻发布会,介绍党的十八大以来水利发展成就。会上有记者提问:党的十八大以来,有关华北地下水超采的综合治理和河湖生态补水工作进展如何?李国英对此作出如上回复。

C | 李国英指出,由于历史原因,华北地区河湖生态环境遭到过严重损害,地下水严重超采,并造成了大面积地面沉降。

D | 水利部会同国务院有关部门、有关地方人民政府采取“节、控、换、补、管”等措施,大力实施华北地下水超采综合治理。

E | 一是“节”,即节约用水,强化需求端的节约用水。在华北地区采取三项措施,农业节水增效、工业节水减排、城镇节水降损。二是“控”,即严格控制地下水开采规模和开采强度,对于第一用水大户农业,采取休耕轮作、发展雨养农业这种方式。同时,严控高耗水产业发展。三是“换”,即对地下水进行置换,以地下水为水源的这些产业、部门,把他们的用水方式换成引用地表水,利用南水北调中线调水、南水北调东线调水、黄河水、本地的地表水,以及本地产生的非常规水资源,对各行业、各部门地下水源进行置换。四是“补”,华北地区地下水源的补充来源,主要是地表河流和湖泊。一段时期以来,华北地区的河道发生了断流,湖泊长期干涸了,意味着地下水的补充来源没有了。所以现在又在更大范围内考虑,向华北地区的河道和湖泊进行生态补水。

F | 这两年水利部加大力度,向永定河补水、向白洋淀补水、向京杭大运河黄河以北段补水。五是“管”,对地下水的开采实施严格管控。首先是对华北地区地下水超采区进行范围划定,划出禁采区、限采区,然后在这个区域内实施严格的管理。

G | 特别是对于深层地下水超采区,对开采的机电井实施关闭甚至封填。同时,建立地下水监测系统,严格地监督考核。李国英表示,通过实施“节、控、换、补、管”这五项措施,这几年华北地下水超采治理取得了明显成效,主要反映在这几个方面:2021年12月底,最新的统计数字和2018年同期相比,华北地区地下水超采治理区浅层地下水回升了1.89米,深层承压水回升了4.65米。同时,监测结果显示,这些年回补地下水累计达到了80亿立方米。从地表的河流和湖泊来看,永定河恢复了过流、潮白河恢复了过流、滹沱河恢复了过流,白洋淀重现生机,断流干涸了将近一百年的京杭大运河黄河以北段今年也实现了全线过流贯通,实现了与永定河的百年交汇。
