蜿蜒于京城西北的永定河是北京最大的河流.然而北京人对她了解多少?她从起点奔流而来的一路上都遇见了些什么?为什么称她为北京的母亲河?带着这一连串问题,"十·一"长假期间,我们骑着自行车,伴随永定河穿越上百公里的官厅山大峡谷,从起点一直走到北京小平原,螂了这条母亲河及沿途景观.
Winding its way through the northwest of Beijing,Yongding River is the biggest river in the city.How much do people living in Beijing know about her？what happen in her journey？Why call her the mother river？With all these questions,we traveled by bike along the river from the grand canyon of Guanting Mountain to the small plain to observe the river and landscape on the way.
