2017-08-15 06:39:28   中国经济网

经济日报北京8月14日讯 (记者曹红艳)环境保护部今天公布了今年上半年各省区市水质情况和水质下降断面。总体来看,全国水环境质量呈改善趋势,但各省区市工作进展不平衡,部分地区完成2017年水质目标难度较大。

根据公布的情况看,上半年,全国地表水水质优良(I至III类)水体比例为70%,同比上升1.2个百分点。这一指标2017年的年度目标为68.3%。同时,上半年,全国地表水丧失使用功能的(劣于V类)水体比例为8.8%,同比下降1.7个百分点。这一指标2017年的目标为8.4%,仍需继续减少“坏水”比例。

统计显示,河北、吉林、福建、江西、广西、重庆、贵州、陕西等8个省区市水质优良水体比例同比下降,即“好水”减少;内蒙古、黑龙江、江西、贵州、陕西等5个省区“坏水”增加,即丧失使用功能水体比例同比上升。

从水质断面看,今年上半年,全国共有27个断面水质下降。其中,涉及河北省4个,吉林省3个,陕西、山西、山东、辽宁、江西、贵州等省各2个,云南、四川、黑龙江、广西、广东、福建、北京、安徽等省区市各1个。
