基本介紹

貴(gui)(gui)州綏陽雙河洞國(guo)家地質公(gong)園，位于貴(gui)(gui)州省遵義市綏陽縣，旅游區地理位置(zhi)優(you)越，交通便利。隨著遵(zun)義機場的(de)開通和公(gong)(gong)路建設的(de)不斷完善，公(gong)(gong)園交通將更加方(fang)便。雙河洞國(guo)家(jia)地質(zhi)公(gong)(gong)園屬于(yu)大婁山山脈(mo)，海(hai)拔(ba)在6001700米之間，地(di)形切(qie)割(ge)強烈，相對(dui)高(gao)差大，地(di)貌類型除(chu)太陽山、金林山一線至(zhi)干河溝為構造侵(qin)蝕中山外，多(duo)數地(di)區為喀斯特峰(feng)從洼地(di)及峰(feng)從谷地(di)，形成了溶(rong)洞、峰(feng)叢谷(gu)地、峰(feng)叢洼地、盲谷(gu)、天(tian)窗(chuang)、地下河、豎井、天(tian)坑(keng)等(deng)地貌形(xing)態。雙河溶洞群所在的桂花村(cun)和(he)銅鼓村(cun)，深山蒼莽，群峰(feng)秀麗(li)，洞(dong)外有兩條河流在(zai)銅鼓村(cun)交匯，雙河溶洞(dong)因此得名。是一(yi)座集旅游觀光、洞穴(xue)探險、科學研究(jiu)于一(yi)體的洞穴(xue)系(xi)統。溶洞群主要有(you)石膏洞、水簾(lian)洞、蓮花(hua)(hua)洞(dong)、桂花(hua)(hua)洞(dong)(大風洞(dong))、山王洞(dong)、羅貴州(zhou)綏陽雙河洞洞穴系(xi)統教(jiao)洞(dong)(dong)(dong)、連(lian)望洞(dong)(dong)(dong)、杉林洞(dong)(dong)(dong)、羅漢洞(dong)(dong)(dong)等，各洞(dong)(dong)(dong)都有鮮明的特色。雙(shuang)河(he)溶洞群(qun)洞穴景觀因其(qi)獨特性(xing)(xing)、多樣性(xing)(xing)、完整性(xing)(xing)而(er)被喻為“喀斯特天然洞(dong)穴博物館”。優(you)美(mei)原始的生態環境，濃厚(hou)的鄉土氣息(xi)，恬(tian)淡的田園風(feng)光，廣布的森(sen)林(lin)溫泉景觀，構成洞集洞、林(lin)、山、水以及地(di)下與地(di)表景(jing)觀為一體的風景(jing)區(qu)(qu)。園區(qu)(qu)還有日流量(liang)達(da)1000立方米的溫(wen)泉，溫泉水溫38攝氏度(du)，以富含硫、鐵(tie)、鋅(xin)、氡而著名。

景點景觀

蓮花洞

蓮花洞(dong)(dong)(dong)位于讓水(shui)(shui)峰從槽谷(gu)景區內(nei)，為一(yi)水(shui)(shui)洞(dong)(dong)(dong)出口，洞(dong)(dong)(dong)口高80米，寬8米，洞(dong)(dong)(dong)的后端有一(yi)處20多米高的三級地下瀑布。地下瀑布是地殼發(fa)生(sheng)垂直錯(cuo)動，使水(shui)(shui)洞(dong)(dong)(dong)前(qian)后段發(fa)生(sheng)垂直位移形(xing)成的。蓮花洞(dong)(dong)(dong)中的流(liu)水(shui)(shui)也(ye)有豐枯的季(ji)節變(bian)化。豐水(shui)(shui)時節，水(shui)(shui)流(liu)從洞(dong)(dong)(dong)中涌(yong)出，在洞(dong)(dong)(dong)外形(xing)成一(yi)道瀑布。

大魚泉

該(gai)泉出(chu)露(lu)高程(cheng)為(wei)660米，補給區位于雙(shuang)河(he)洞(dong)地質公園(yuan)西部讓水(shui)一帶(dai)，平水(shui)期流量為(wei)每(mei)(mei)秒436升，洪水(shui)期流量達(da)每(mei)(mei)秒2-3立方米。該(gai)泉有三大特點：一是水(shui)的顏色因含銅而呈深綠色，注入池武溪(xi)(xi)形成“涇(jing)渭分明”現象(xiang)；二是每(mei)(mei)逢炎熱(re)少雨季節(jie)，地下水(shui)補給不足，彎曲(qu)的洞(dong)道就會產生虹(hong)吸(xi)現象(xiang)，形成間歇泉，每(mei)(mei)1小時左(zuo)右出(chu)一次水(shui)；三是常有大大小小的細鱗魚和小黃魚從泉中涌出(chu)來，向池武溪(xi)(xi)游去，大魚泉因此得(de)名。

公館橋

公(gong)館橋(qiao)(qiao)位于綏陽、正(zheng)安兩縣(xian)交界的(de)赤(chi)尾溪河(he)上，地(di)(di)處雙河(he)洞國家地(di)(di)質公(gong)園內。這座橋(qiao)(qiao)始(shi)建于清光緒(xu)三十二年(nian)，竣(jun)工于宣統元年(nian)（公(gong)元1907-1910年(nian)），采石(shi)(shi)于附近姚坪山(shan)，是正(zheng)安州知州郎(lang)承謨創建，為黔北(bei)第(di)一大獨拱(gong)石(shi)(shi)橋(qiao)(qiao)，稱為“正(zheng)南(nan)第(di)一橋(qiao)(qiao)”。橋(qiao)(qiao)以(yi)方條石(shi)(shi)砌成，全長72米(mi)，跨度(du)23米(mi)，寬7.2米(mi)，基腳(jiao)與橋(qiao)(qiao)面護欄通(tong)高(gao)18米(mi)，橋(qiao)(qiao)南(nan)有(you)石(shi)(shi)級(ji)47級(ji)，橋(qiao)(qiao)北(bei)有(you)石(shi)(shi)級(ji)40級(ji)。橋(qiao)(qiao)兩頭雄踞著4頭各1.5米(mi)高(gao)的(de)石(shi)(shi)獅，橋(qiao)(qiao)欄上雕刻著鯉魚跳(tiao)龍門、神仙下棋等神話故事圖，以(yi)及奇花(hua)異(yi)草、古禽怪獸圖案，和多幅對仗工整(zheng)的(de)對聯。
