张家口地区的黄羊滩沙地，是北京沙尘的源地之一。北京军区１０年来的植树造林，已经使黄羊滩部分上地绿树成林，中国国际信托投资公司也出资５００万元在黄羊滩开展治理工作。多年来，社会各方力量为治理黄羊滩而积极努力，取得了一定成效，但黄羊滩的总体形势依然十分严峻。
Huangyang Beach in Zhangjiakou area is one of the sources of dust in Beijing. The afforestation of the Beijing Military Region over the past 10 years has resulted in the afforestation of some trees on Huangyangtan. China International Trust and Investment Corporation has also invested 5 million yuan in harnessing Huanghuangtan. Over the years, all forces in society have worked hard to harness Huangyangtan and achieved some success. However, the overall situation in Huangyangtan is still very grim.
