五大连池风景区位于黑龙江省西北部的五大连池市、小兴安岭西南侧山前台地上,距北安市60公里。四周分布着14座火山体,以及一系列火山矿泉,构成了独特而典型的火山景观,因而有“火山博物馆”之称。是我国著名的火山游览胜地。 由于火山熔岩堵塞的河道,形成了五个相连的火山堰塞湖,因其形如串珠状,故称“五大连池”。 五大连池地区火山群海拔高度为400米-600米,以火山锥的特殊结构、各种火山熔岩流动形迹、结满冰霜的熔岩隧道,以及冷碳酸矿泉而闻名于世。 五大连池火山群位于松嫩断陷盆地北端,其东北是小兴安岭断裂抬升区。五大连池火山群还处于北西向五大连池—科洛火山带上。区内分布的地层主要有石炭系千枚岩、片岩、白垩系及第三系的砂岩、第四系火山岩,并有华力西及燕山期花岗岩。 五大连池火山群有14个独立的火山锥和一系列盾状火山。火山锥和盾状火山形成于第四纪,而最近的火山喷发,则于公元1719年-1721年,发生在老黑山和火烧山。此次喷发溢流的熔岩在四个地方阻塞了区内的石龙江,形成了五个火山堰塞湖,最终形成“五大连池”。 地球在长达46亿年的复杂演化过程中,为人类提供了优美的自然环境和丰富的物质资源。五大连池就是第四纪火山活动给人类留下的一片珍贵遗产,这里山秀、水幽、泉奇、石怪、洞异,是集生态旅游、休闲度假、保健康疗、科学考察为一体的高含量、多功能、综合型风景名胜区,被誉为镶嵌在欧亚大陆桥上的一颗璀璨的明珠。 据讲,五大连池火山在我国辽金时代被称为“乌云和尔冬吉火山”,当时,无人在此居住。伴随着两座新期火山的喷发,火山堰塞湖的形成和疗效神奇的矿泉水的出露,才有游牧民族达斡尔人的迁入,并将这里的火山称为“乌尤里—哈尔多格火山”,对池水称为“乌德邻池”。后来由于汉人的大量迁入垦荒种地,这里便被汉人称为五大连池位于黑龙江省德都县境内,距哈尔滨市413公里。是北方的一处旅游、疗养胜地。五大连池是火山喷发的熔岩流堵塞了白河河道,形成五个串珠般的湖泊而得名。这里是一组休眠的火山群。在五大连池周围,分布有14座火山和60多平方公里的熔岩台地。这组火山群,拔地而起,形态各异,形成了一个别具一格的风景区,人们也称这里为“火山公园”或“自然火山博物馆”。 五大连池主要有两大特色:一是景色奇特。由火山喷发的熔岩形成的熔岩,有的像一条长龙,有的如象鼻在吸水,有的像一条瀑布,形象逼真。还有一种外观十分好看的“石塔”,高约二三米,这也是火山熔岩层层盘叠而成的。熔岩在地下流动形成的熔岩空洞,也是旅游者感兴趣的地方。在这里,游客们可以拾一两块形状奇特的熔岩留作纪念。二是这里有丰富的矿泉资源,很多地方都有矿泉水涌出。这些矿泉多为冷矿泉,水温低,含有十几种对人体有益的元素,统称为重碳酸矿水。这种矿泉水可饮可浴,能治疗胃病、神经衰弱、皮肤病、高血压等病症。现在这里已经建了几十座矿泉疗养院。 五大连池的主要游览点有:五大连池、药泉山公园、火山博物馆。五大连池的五座池之间相互连通,纵长20公里,池水面积40平方公里,最深处百余米。药泉山海拔350米,是14个火山锥中规模最小的一个,因为泉水有药物作用,被称为“圣水”。园内有各种风景建筑。火山博物馆,是由于老黑山、火烧山喷发于1719-1721年,为我国最新期火山,有保存完整的火山地质地貌。这一带便被称为火山博物馆。 五大连池除五个堰塞湖外,还有许多古代和近代的火山。中、近期形成的火山共14座,其中老黑山和火烧山年龄最小,但体态庞大,景色尤佳,是五大连池中最佳景区。老黑山山势高耸,植被葱郁,相对高差达166米,是14座火山中最高的一座。山的东、北两侧有盘山道可达山顶,山顶有漏斗状火山口,直径350米,深达140米。火山口周围有人行步道,俯视火山口底令人望而生畏。山上东北角有火山熔洞,洞内熔岩倒挂,景致千姿百态。 火烧山规模较老黑山小,植被很少。焦灼的火山口把整个大山劈为两半,裂缝狰狞,状态怪异,山坡中随处可见大小不一的火山弹。 老黑山和火烧山的四周为熔岩台地,总面积达65平方公里。当年喷出的熔岩沿白河向南流去,形成了蜿蜒10公里长的“石龙”。石龙景象举世罕见,远看像大海汹涌的波涛,近视则怪石嶙峋,千态万姿,形态生动奇特,如熊如虎如蛇如绳如巨莽。奇特的熔岩暗道、熔岩空洞中,更有奇特的熔岩钟乳,如角锥如僰刺如刀刃或如薄板,如贴附在洞穴的四壁,蔚为奇观。 五大连池火山群是中国最年轻的火山群,火山地质遗迹现象最齐全、分布最集中、保存最完整、景观最典型,该地分布的喷气锥为世界罕见,有“火山地质博物馆”之称。 五大连池火山富钾碱性熔岩,SiO2含量高,它是钾质火山岩的一种典型代表,对探讨板块活动、岩浆演化具有重要意义。 五大连池有“中国矿泉水之乡”之称,其南泉、北泉的碳酸型矿水,不仅是中国矿泉水之极品,也是世界矿泉水之珍品,对医疗及饮用均具重要价值。 与五大连池火山具有可比性的世界著名火山有美国夏威夷火山、印度洋中的留尼旺火山、法国的中央高地火山几东非裂谷乌干达境内的托罗——安科尔火山等。 相同的是这几座世界著名的火山与五大连池的岩浆都属基性,其火山活动方式均属于夏威夷式喷发,火山喷发后形成的火山地貌景观也基本相似。 不同的是,这几座火山的规模均比五大连池火山大,其形成的某些火山地貌景观也比五大连池火山地貌更壮观。然而,五大连池火山地貌更齐全、更集中、更典型。比如,在这几座世界著名的火山附近,均未形成火山堰塞湖,而且除法国中央高地火山区外,均未发现矿泉出露,喷气锥、喷气碟更是少见,仅在印度洋中的留尼旺火山区偶见个体矮小、发育形态不完整的喷气锥、喷气碟。 相比之下,五大连池火山形成的山川辉映、水火相容的火山地貌景观更有特色。而翻花熔岩中发育完整、保存完好、多姿多态、数以千计的喷气锥,在世界其它火山区绝无仅有,可谓世界奇观。 五大连池拥有举世罕见的六大自然环境——这里有世界上最纯净的天然氧吧;有世界上品位最高的具有医疗保健作用的磁化矿化电荷离子水;有集保健、美容、医疗于一体的矿泉洗疗、泥疗场地;有天然的火山熔岩台地——阳热能理疗床;有功能最齐全、规模最大的火山地质全磁环境;有不受任何污染的纯绿色健康食品生产区。由此形成了世界上综合条件最完善的自然环境理疗基地。 五大连池已开发七大游览观光区、八大奇观、一百多个景点。七大游览观光区包括:新期火山奇观观光区;世界著名冷矿泉观光区;火山堰塞湖观光区;古火山遗迹观光区;火山熔岩冰雪洞游览区;古火山石寨科考观光区;火山民俗文化观光区。八大奇观有:雄峻陡峭的山巅火口;波澜壮阔的翻花石海;鬼斧神功的龙门石寨;碧水一泓的天池胜景;霜花似玉的熔岩冰洞;造型奇绝的喷气锥碟;云雾蒸腾的石龙温泊;景色如画的群山倒影
