新华社北京4月27日电(记者 高敬、侯雪静)据气象水文预测,今年主汛期,全国降水接近常年略偏少。主雨带可能位于长江上游至黄淮一带,西江、长江上中游、太湖及淮河可能发生较大洪水,辽河、海河、黄河可能发生暴雨洪水。

国家防总办公室督察专员、新闻发言人张家团27日在新闻发布会上表示,今年我国防汛抗旱防台风形势依然严峻。除上述可能发生洪水的地区外,西北东部、东北北部、江南中部等地降水偏少,发生夏旱的概率大;台风登陆个数可能偏多,强度偏强。

他介绍,今年以来,全国主要江河来水量较常年同期总体偏多。其中,淮河偏多7至8成,辽河偏多6成,长江偏多2至4成。与此同时,海河流域拒马河偏少近8成,黄河上游偏少近1成、中下游偏少2至3成。

目前,南方主要江河水位偏高,与常年同期相比,西江偏高1.02米,淮河偏高0.31至0.63米,长江下游及鄱阳湖水位较2008年三峡水库正式蓄水以来同期均值偏高0.36至0.55米。

张家团介绍,针对去年汛期,一些地方水利工程毁损严重的不利局面,各地扎实开展水毁工程修复工作。据统计,2016年全国水利工程设施水毁共17.57万处。截至4月27日,各地已完成水毁修复17.24万处、占总数的98.1%。

他表示,为确保今年防洪安全和供水安全,一要强化监测预警预报。加强与气象水文联合会商,及时研判防汛抗旱形势。

二要进一步夯实各项准备工作。督促各级防指和有关部门强化防汛抗旱责任制落实;全面排查长江干流崩岸险情;确保主汛期前全部完成水毁工程修复任务;抓紧修订完善防汛抗旱各项方案预案;加快完成抢险队伍和物资准备;强化业务培训和预案演练。

三要科学调度水利工程。加强水库迎汛备汛调度,合理确定运行水位,充分发挥综合调蓄作用和防洪减灾效益。

四要有效应对汛旱灾情。加强应急值守,做好灾害应对,确保重要目标防洪安全和供水安全。
