2020微山县计划投资5400万元改善旅游生态环境

 　 微山县为改善流域生态环境，计划投资5400余万元，启动大、小沙河人工湿地水质净化工程。这两项工程主要利用截污导流工程在河流上游处建设橡胶坝，抬高河上游河水水位，并沿河建设引水渠道，采用重力流形式将污染河水引至湿地工程区，通过湿地系统对污染河水的深度净化，处理后水质达到《地表水环境质量标准》(GB3838-2002)Ⅲ类标准后排入南四湖。

　　工程建成后，可明显改善大、小沙河水质，逐步恢复河道的生态环境，湿地系统还可为诸多生物提供适宜生长的环境，在增加生物多样性、生态系统的复杂和稳定性、维持自然平衡中起到非常重要的作用。同时，还将增加南四湖的环境容量，为湖区人民群众生产、生活带来巨大经济效益，改善旅游生态环境，促进南四湖流域经济环境共赢发展。
