Summary[edit]

Description
中文(臺灣):  宜蘭河川豐枯期水量變化差異大,又因受東北季風、颱風及全球氣候變遷之影響,每逢枯水期時,河道水位降低甚而出現河床裸露,又上游沖刷至下游的細粒質粉土不斷覆蓋於河床,每當強風吹襲,常夾帶大量砂塵,更加劇揚塵現象。其中尤以蘭陽溪中下游一帶最為明顯,嚴重影響當地居民的健康及生活品質。

  為了改善塵沙飛揚現象,水利署第一河川局自2011年起,積極著手規畫揚塵抑制工法及植生復育芒草區域,從蘭陽溪中下游牛鬥到河口,逐年增加面積;並配合減少河床中種植等相關使用行為,以達到最佳之植生覆蓋效果,今已略見抑制揚塵現象。

  「芒草韌性高,隨便種、隨便活」第一河川局表示,原本是選擇栽種狼尾草,後來發現芒草和甜根子草成效更好,卻也在無意間讓蘭陽溪畔有了整片白茫茫的芒草花海,尤其是河床上甜根子草銀白色的花穗,像羽毛般輕逸的隨風擺盪,景色層次極為豐富,成了季節限定的美麗景緻。
