台湾:抢救消失的海岸线

2017-08-25 04:31:11   中国青年网

如今为留住消失的海岸线,沙滩上钉满消波块,美景早无踪影。

在赴台游客心中,台湾的原始海岸线是最美的风景之一,碧海蓝天,细沙椰林,柔风拂面,世界忽然安静下来,心中只剩纯净唯美。然而,想要体验的游客如今要趁早了,因为受多种因素影响,近年来台湾的海岸线大幅后退,海洋生态资源面临严重威胁,许多美景被大海吞噬,不断消失的海岸线亟待抢救。

“涨潮时就半沉海中”

“全台海岸线都在退缩。”台湾高雄市水利局官员说,他们下辖的旗津区原本是旅游热门地,但海岸线遭严重侵蚀,短短几年海浪拍到民宅门口,最严重时原本离海几十米远的房屋都快要保不住。茄萣区也已被列为一级海岸防护区,海岸线10多年来遭严重侵蚀,其下辖的崎漏里大片沙滩退缩上百米。

台湾“经济部中央地质调查所”监测数据显示,全台至少12处海滩和沙洲正严重流失,过去30年退缩了100到650米,总长约1576公里的海岸线正在慢慢缩短。岛内媒体苦笑称,不断消失的海岸线让台湾陆地轮廓变了样,“从胖番薯变瘦地瓜”。

嘉义县布袋镇好美里海滩20多年前曾举办过风帆船比赛,当时选手必须从堤岸步行约60米才能抵达海滩,如今只要遇到大潮,海水就直逼堤岸。位于布袋镇与东石乡交界处的寿岛,原本“海岸巡防署”官兵车辆出入岛通行无阻,现在涨潮时,寿岛就“半沉”海中。

10多年前,台南黄金海岸夕阳时分的“海天一色”美景让很多人为之沉醉。可昔日“最美沙滩”在海浪侵蚀下“节节败退”,如织游人早已不再,只能听到涌浪打在消波块(放在岸边用来固定泥沙的水泥墩子)上发出“轰、轰、轰”的巨响。

是谁“谋杀”了台湾海滩

是谁“谋杀”了这些美丽海滩?

台湾师范大学地理学系副教授林宗仪通过研究得出结论:保护海岸用的消波块和水泥堤防,其实正是杀手。“离岸堤做到哪里,下游就开始侵蚀。”

66岁的王博文,家中世代在台南市北门区海边捕鱼为生。他说,20多年前北门开发养殖后,在外围筑起堤防,印象中从那时开始,海岸就逐渐倒退。现在堤防加到5米高,海岸“起码退了1000米远”。
