黄河凌汛黄河凌汛ice flood of Huanghe Riverhuanghe Iingxun黄河凌汛(iee flood of Huallshe斑ver)黄河流域位于中国中部，界于北纬32.50一41.70与东径96“一119’之间。河道迁回曲折，流向变化大，其中，上游的内蒙古河段和下游的河南、山东河段河道水流方向偏北、坡降平缓，常有严重的凌汛发生。上游宁夏、内蒙古河段凌汛本段地处黄河流域最北端，干流长320公里，河道形势呈一倒‘’U”字形(见图1)。黄河由宁夏进入内蒙古境后，河身逐渐由窄深变为宽浅，河道坡降减缓，浅滩弯道叠出，平面摆动较大。该区冬季严寒漫长，最低气温可达一35oc，河段年年封冻，是一个稳定封冻河段。历年出现流凌的时间一般在11月下旬，封冻日期为12月上、中旬，解冻日期在3月中、下旬，冰期约100天，冰盖厚度0.7米左右。黄河从上游的甘肃兰州至内蒙古河段，纬度增加4‘37’，致使上下游的冬季月平均气温差约soC，包头河段的流凌封冻比兰州早20多天，而解冻却晚一个多月。使内蒙古河段封冻时溯源而上。解冻时则由上而下，构成了复杂的冰情现象。河道自宁夏石咀山市进入内蒙古以后，即穿行于峡谷之间，河身狭窄解冻时流冰常在弯曲段受阻。出峡谷后河身逐渐放宽，但多畸形大弯。自巴颜高勒至托克托，较大弯道有69处。冰凌极易在弯道处堵塞，形成冰塞和冰坝，引起水位陡涨，凌汛期峰水位常常接近或越过同年伏汛期最高水位。这段河道年年均有程度不同的凌害发生。岁娜，截0固阳马头一~一理呼和浩特}“刁举黔‘产牛托彭毛0杭锦旗乌海撇)愁石嗯饭L砚色急科鄂托克旗神水黑乃‘|斗l石、l!一份少___吴忠一决--一州一下 6州月升中卫0定边宁|渗申同划、黑山峡景秦声厂红山峡o娜}、大宁延安3逐104哦o洛川}、龙门图l黄河宁、河南、山东河段凌汛该河段地处北纬34.55’一38’o『之间，干流长800多公里。河段封冻概率约80%，是一个较不稳定的封冻河段。河道自河南兰考东坝头以下呈西南至东北流势。至山东垦利入海处，纬度增加3’左右。
