新华社北京７月３０日电（记者林晖）进入七月下旬，全国防汛形势骤然紧张：华北、西北降雨不断，长江、黄河“洪水齐发”，新生成的热带风暴正向东南沿海逼近……全国防汛已经进入“七下八上”最关键时期。

    Beijing, June 30 (Reuters)（Reporter LinHui）In late July，The flood control situation suddenly nervous：North China、Northwest rainfall constantly，Yangtze river、The Yellow River“The flood qi”，The new generation of tropical storm is southeast coastal approximation......The national flood control has entered“Seven on eight”The key period。

    从地域上看，以往缺水的北方地区今年以来降水频繁，北京、天津、河北等地多次遭遇强降雨袭击，造成泥石流、山洪、城市内涝等重大灾害。中央气象台最新预报显示，未来１０天，华北中南部、东北等地依然多阵性降雨，防汛工作不容松懈。

    From regions see，Before the water shortage in the northern region of since this year precipitation frequently，Beijing、tianjin、Hebei encounter many times heavy rainfall attacks，Cause mudslides、Flash floods、Cities such as the potential disasters。The central weather forecast shows the latest，The next 10 days，South north China、The northeast, still DuoZhenXing rainfall，Flood control work not lax。

    从大江大河看，目前淮河、珠江、松辽流域汛情较为平稳，但长江、黄河“洪水齐发”，沿线防汛形势十分严峻。

    From big rivers and look，At present the huaihe river、Pearl river、XunQing songliao basin is more stable，But the Yangtze river、The Yellow River“The flood qi”，The situation is very serious flood along。

    今年长江中上游已经迎来４次洪峰，其中第４号洪峰７月２４日晚抵达三峡大坝时流量为每秒７．１２万立方米，是三峡水库建库以来的最大洪峰。在国家防总、长江防总的科学调度下，三峡水库将洪水“拦腰”削去四成，充分发挥了削峰驯洪作用。但据气象部门预报，长江上游近期仍有降雨过程，三峡水库防洪压力仍未缓解。同时，为了给下一次洪水腾出库容，三峡水库正维持较大的下泄流量，长江中游部分江段和洞庭湖防守压力较大。

    This year has been four times in the Yangtze river reaches the peak，Among them 4, flood peak arrived in late July 24, three gorges dam for 71200 cubic meters per second volume flow，The three gorges reservoir is the biggest since the flood peak construction of the database。In the office、The science of the Yangtze river office under the scheduling，Will the three gorges reservoir flood“lazio”Cut to forty percent，Give full play to the peak flood cut role。But according to forecast the weather department，The upper reaches of Yangtze river are still recent rainfall process，The three gorges reservoir flood still did not relieve the pressure。At the same time，In order to make the next flood capacity，The three gorges reservoir are analyzed to maintain larger，Part of the Yangtze river JiangDuan and defensive pressure great dongting lake。

    在黄河流域，今年１号洪峰已过潼关，２号洪峰已经形成并向下游推进，黄河中游吴堡、龙门等部分河段洪峰流量超警。据气象部门监测，今年以来黄河上游降水量比同期偏多三成，创１９６１年以来历史极值。预计８月至９月上旬，黄河流域大部地区降水量仍偏多，防汛形势依然严峻。

    In the Yellow River basin，1 this year has been the changes of the peak，2 flood peak has been formed to promote and downstream，The middle Yellow River at wu、The goal of the peak flow river super p。According to the weather department monitoring，Since this year the upper reaches of the Yellow River in the same period thirty percent more than rainfall bias，And history since 1961 extreme value。Expected early from August to September，In most parts of the Yellow River basin is still partial precipitation，Flood control and it is still severe。

    与此同时，今年第９号热带风暴“苏拉”和第１０号热带风暴“达维”正向我国东南沿海靠近。据了解，“苏拉”的云圈、风圈、雨圈半径大，水汽条件充沛，可能带来较强降水。由于两个热带风暴的相互作用，后期路径存在变数，并可能形成强风、暴雨、高潮位“三碰头”的不利局面，增大了防御难度。

    At the same time，This year 9, tropical storm“sura”And 10, tropical storm“davey”Positive near the southeastern coast of China。According to understand，“sura”Cloud circle、FengJuan、The rain circle radius big，Abundant water vapor conditions，May bring more rain。Since the two tropical storm interaction，Later existing path variables，And might form a strong wind、Heavy rains、Climax a“Meet three”Adverse situation，Increase the difficulty of defense。

    国家防总副总指挥、水利部部长陈雷在国家防总防汛会商会上表示，当前正值“七下八上”防汛最关键时期，东南西北降雨频繁，长江黄河洪水齐发，两个台风相互影响，“防汛形势最复杂，防汛工作最艰巨，防御任务最繁重。”他要求有关地区防指和流域防总要立足于防大汛、抢大险、救大灾，着力做好当前防汛防台风工作。

    The office deputy commander in chief、The ministry of water resources minister Chen lei in the office flood control in consultation with the meeting said，The current when“Seven on eight”The key period for flood control，East, west, frequent rainfall，The Yangtze river flood qi，Two typhoon influence each other，“Flood control and the most complex situation，The most difficult of flood，The most onerous task defense。”He asked about the region and watershed office refers to the should base on the DaXun、Rob big risks、Save great evil，Strive to do the current flood prevention work the typhoon。

    目前，国家防总已向山西、陕西、甘肃、青海、宁夏和内蒙古等省区发出紧急通知，要求进一步做好强降雨防范工作，并向湖南、湖北加派２个工作组协助指导长江抗洪抢险。

    At present，The office has to shanxi、shaanxi、gansu、qinghai、Ningxia and Inner Mongolia and other provinces issued an emergency notice，Requirements well further heavy rainfall prevention work，To hunan and、Hubei send two working group to help guide the Yangtze river flood prevention emergency rescue。
