A | (ECNS) -- Beijing Subway Line 22, the capital's first urban rail route linking neighboring Hebei Province, began empty load trial operations Tuesday, according to the Beijing Major Projects Construction Headquarters Office and BII Railway Transportation Technology Holdings Company Limited. Stretching about 79.1 kilometers with a speed up to 160 km/h on elevated sections and 120 km/h underground, Subway Line 22 runs from Hongmiao in Chaoyang district to Pinggu New Town, with 20 stations in total, including 15 in Beijing and five in Hebei. Once operational, travel from Yanjiao Town in Hebei to Beijing's Sub-Center Station will take just nine minutes, while journeys to Hongmiao Station in the capital's central business district will be about 28 minutes. Officials described Line 22 as a "major transport artery" for regional integration. The route will connect with multiple existing lines, including transfers at Hongmiao to Line 14, Guanzhuang to Line 1, Beiguan to Line 6, and Beijing Sub-Center Station to Line 6 and the Beijing-Tangshan intercity railway. The line is expected to be ready for opening by year's end. (By Gong Weiwei) 
。 本报讯 山洪沟治理工程既是一项重大的民生工程，也是一项重大的生态工程。
B | 今年，龙港区围绕保障和改善民生，推进山洪沟防洪治理，提升山洪灾害防御能力，筑牢“安全堤坝”。 烈日当空、骄阳似火。
C | 近日，笔者在荒地河山洪沟治理工程现场看到，河道内水波荡漾，两岸建起一块块可栽绿植的生态框，框架内部可以实现孔隙排水，使水分迅速排出，可以有效防止坡面积水和雨水渗透导致坡面坍塌。 据了解，荒地河全长4500米，治理长度3000米，南起荒地村外，北至锦葫路，其中固滨石笼护岸2200米，生态框1600米。
D | 目前，山洪沟防洪治理项目主体工程已完工。不仅能有效提升河道防洪行洪能力，还能改善沿岸人居环境及生态环境，提高区域绿化空间，绘就河畅水清岸绿景美的生态画卷。 据区农业农村局副局长介绍，山洪沟原貌基本处于土质岸坎无防护状态，暴雨后易造成河水漫灌、河道淤积、水土流失严重等灾害，威胁河道两岸群众安全，现在在河岸两侧使用了生态框与固滨笼相结合的方式进行治理，有效减缓了洪水冲刷力，使生态环境和水土保持得到改善。通过这项治理将有效预防安全隐患，保证河道行洪安全。（赵家艺）。
