全国水环境质量呈改善趋势

2017-08-15 04:16:07   中国青年网

新华社北京8月14日电 (记者高敬)环境保护部14日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。

其中,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。
