恢复湿地生态 保护鸟类栖息地
2017-08-25 06:47:29 中国青年网
本报讯(记者 王睿)互花米草是一种繁殖力极强的绿植,也正由于这个原因,互花米草现在已经成为津冀渤海地区最主要的入侵物种,严重威胁着沿海地区的生态平衡。记者昨日获悉,针对互花米草泛滥的情况,滨海新区出台相关治理方案,启动对永定河口至河北交界处沿海滩涂互花米草进行专项治理,以获得适宜本地区的成功治理技术,恢复湿地生态,保护鸟类栖息地和迁徙通道。
在滨海新区蔡家堡附近的沿海滩涂,记者看到,互花米草占据了大片面积,工作人员正针对互花米草实施化学除草剂的喷洒。据介绍,这一带的沿海滩涂是国家一级保护动物遗鸥重要的栖息地。遗鸥是鸥类水鸟家族中最晚被人类发现并认识的鸟,因此而得名,意为“被遗忘的鸟”,在2012年的全球水鸟种群估计中,遗鸥数量约1.2万只。鸟类学专家介绍说,天津作为遗鸥的重要越冬地,近年来,每年到滨海新区沿海滩涂越冬的遗鸥就有1.1万只。
“绝大部分集中在这片滩涂越冬,泥质海滩的保护非常重要,互花米草逐年泛滥,正侵占大量沿海滩涂,现在仅汉沽区域就达到2000多亩。”滨海新区汉沽林业站站长王峰介绍说,在秋季候鸟迁徙大潮到来前夕,为了修复受损湿地功能,给候鸟营造良好的栖息环境,整治互花米草刻不容缓。采访中记者了解到,按照相关治理方案,今年,滨海新区将继续开展永定河河口至河北交界处互花米草治理实验,治理面积1000亩。
