“北风那个吹,雪花那个飘”,想必大家对著名歌剧《白毛女》的这个选段选还记忆犹新,只不过这两天北方飘的不是雪,是浓浓的沙尘。铺天盖地,蔚为壮观。

5月3日晚至目前,内蒙古自治区遭遇沙尘暴天气,空气发黄混浊,能见度降低,气温下降。内蒙古呼和浩特市、包头市、巴彦淖尔市等地空气质量指数均在500以上,为严重污染。 石斌 摄

今天一大早,北京发布沙尘暴蓝色预警和大风黄色预警。漫天沙尘,空气里一股浓重的土味,还别有一番滋味,让人仿佛又回到了冬天的雾霾天,重温那些“云里雾里”的日子……

所以这两天朋友圈晒的不是早餐,而是“早餐里面有沙子”般的悲嚎。北京二月吃霾三月吃沙,四月吃絮,五月整来了个套餐。生活在北京的群众吐槽起来可不带手软的。

“大漠风尘日色昏,红旗半卷出辕门。”这是唐代著名诗人王昌龄描写西北大漠的诗句。生活在北方的小伙伴“有幸”体验到了这一幕壮观景象。从昨天开始,包括北京在内的内蒙古、东北地区西部和华北北部迎来了本年度最严重的沙尘天气,局部地区还有沙尘暴。

今年第7次沙尘天气过程从3日开始,是今年以来范围最广、强度最强的一次沙尘过程,从新疆南疆盆地经河套地区一直到华北北部、东北西部的部分地区都出现了扬沙或浮尘的天气,内蒙古西部局地还遭遇了沙尘暴。(中国天气网)

那么问题来了,你知道沙尘暴是从哪里来的吗?沙尘暴治理成效咋样?你有啥建议防治沙尘暴呢?吐槽归吐槽,生活还得继续。一本正经地告诉你,沙尘暴的“老窝”离你有多远。

形成沙尘暴的三个条件:大风、不稳定的天气与沙源

沙尘暴是一种天气现象,是指强风把地面大量沙尘物质卷入空中,使空气特别混浊,水平能见度低于1公里的严重风沙天气。它的发生需要三个条件:大风、不稳定的天气与沙源。人类尚不能消灭沙尘暴,唯一能做的就是控制风与界面的粗糙度,减少浮尘的升空,从而不能随大气环流运行;降低流沙的跃动能力,固定沙丘,阻止沙漠的扩张,保护绿洲。

数据上看,我国近10年沙尘天气呈递减趋势,为何今年沙尘卷土重来?据介绍,北京的沙尘天主要分为外来沙尘和局地扬沙。这一次的沙尘天气就是被大风从上游带过来的。

而上游所在地是广袤的沙漠和沙地。乌兰布和沙漠是东亚地区最大的沙尘源地,是整个阿拉善生态体系的缩影。它是我国干旱与半干旱地区的分界线,也就是亚洲中部荒漠区与草原区的分水岭。每年,西伯利亚寒流与蒙古气旋冷风从这片干燥的土地上掠过,卷起沙尘,横扫大半个中国。

据中央气象台环境气象中心高级工程师张碧辉介绍,客观上来说,最近10年,在人为治理和气候因素的共同作用,沙源地局部环境有所改善。一方面,整个气候变化导致这种影响,我国冷空气总体来说存在减弱减少的趋势;另一方面,近些年我国做了很多防风固沙的工作,包括三北防护林等,沙源地的起沙条件得到一定的改善,不利于形成沙尘天气。

从具体数据来看,2001年是沙尘天气的高发年份,出现沙尘过程22次,沙尘暴过程次数11次,为近年来最多,而到了2014年出现沙尘天气仅有7次。在2010年以后,包括2011年、2014年、2015年、2016年沙尘暴天气过程均不超过2次,2015年仅有1次,但对于此次的沙尘天气不少人也有疑问,既然有三北防护林等防沙手段,却为何还会出现如此大范围的沙尘天气?

生态修复与保护工程——“三北”防护林工程

张碧辉分析解释,三北防护林等措施主要改善局地气候,起到防风固沙的作用,但对于远距离、高空传输的沙尘作用有限。以本次影响北京的沙尘来说,是通过高空5000米的偏西气流传输而来,防护林的高度难以阻挡沙尘。

有哪些途径可以治理沙尘暴?

常规治理

(1)施放添加物改善土壤结构,包括有机肥、软泥、重油、沥青、塑胶型工业废弃物(如淡胶) 等。在水源充足的地方,在雨季到来之前则辅以灌溉。

(2)在耕作方式上一般按一定间距翻耕成行的与风向垂直的大土块,在干燥的耕地中翻挖横断面呈浑圆的土垄,高度不超过40cm。其他耕作措施概括如下:

①免耕或带状耕种:未翻耕的面积小于25%,使用除草剂清除杂草;

②垄耕:在垄上种植,垄间留茬,使用除草剂;

③覆盖耕种:种植之前先翻耕;

④少耕:风蚀季节耕种时保留15%~30%的残茬;

⑤防护性耕种:保留耕地表面的覆盖物;

⑥沿等高线耕种:在坡度小于8度的坡地实施;

⑦汇流的渠、沟等两旁种草和进行沟道治理;

⑧建设防风林。

(3)带状耕作是在周期为2年的休耕和种植轮作中,条带布设成需要的宽度,一厢休耕,相邻两厢种植;在3年的轮作中,两厢种植,第三厢休耕。更好的布局是在每两厢的边缘建立防护林带。尽管防护林存在自身水分的消耗,但可减少蒸腾达20%,因此在灌溉区采取两排高的树外面再种植两排低的树,一定时期后砍伐一半,并在第一年耙地时切断防护林的横向根系,阻止对农作物的竞争。

(4)干旱地区确保合理的作物留茬,以增加地表糙度。

(5)作物采取轮作或间作。谷物之后是豆类,随后是条带状农作物或翻耕,然后再是谷物,同时向土壤增加残余物。随着无机肥的使用,间作在干旱地区的应用更广泛,有几套耕作系统,其中重要之一的是“绿洲型农业”,有两到三层植物用作遮盖层,下面是果树,地表层是农作物层。

(6)可以使用防沙植物有胡枝子、三叶草、苜蓿、野豌豆、大豆、豌豆、野葛、扁豆、芦苇、本地草类、豆类、本地作物、野生作物等。 (7)在地表出现风沙活动的地方,主要采取工程固沙,用高粱属植物或粟的秸秆作防风篱、防护网格。也有在雨季植草或在重点防护地区上风向营造防护林的生物固沙。

政协委员有啥好建议?

丝绸之路经济带沿线很多都是荒漠,直接影响生态和社会发展。我国荒漠化治理经验已得到国际社会认可,建议将沙漠治理纳入“一带一路”建设规划,促进沿途生态建设,开辟国际合作新思路。

土地荒漠化,不仅是生态问题,也是政治、经济、社会和安全问题。土地荒漠化,导致沿线很多地区经济落后、贫困人口集聚,成为制约地区发展和稳定的重要因素。推进“一带一路”建设,必须重视荒漠化问题。

——全国政协常委、亿利资源集团董事长王文彪

风沙危害已成为新疆最为严重的生态问题和最有影响的民生问题,加快沙害治理刻不容缓。建议在加强顶层设计,制定沙化治理长远规划,高位推动防沙治沙的同时,尽快将防沙治沙纳入新疆民生改善项目和对口援疆项目;建立和完善生态修复和生态补偿制度,提高治沙造林和封沙育林补助标准;加大防沙治沙投入力度,加快启动实施新疆防沙治沙专项工程;争取差别化政策,先行先试,开展区域性防沙治沙综合示范区建设。

——全国政协委员陈旗

小提示

【今年最强沙尘傍晚撤离京城 今晚开始撤离】今日,北京室外一片昏黄,能见度很差。前日开始,今年以来北方最强沙尘天气来袭。沙尘影响全国163万平方公里。昨日,北京地区遭遇今春最严重沙尘天气,可吸入颗粒物PM10小时浓度一度破2000微克/立方米。气象部门预计,今日傍晚,北京沙尘天气影响趋于结束。
