高(gao)屯(tun)天(tian)生(sheng)橋(qiao)位于貴州省黎平(ping)縣城東(dong)北12公(gong)里的(de)(de)灣寨右(you)側(ce)處,這座由地(di)下伏流自(zi)然(ran)形成(cheng)的(de)(de)天(tian)生(sheng)橋(qiao)歷來為游客之(zhi)游覽(lan)勝地(di)。此(ci)橋(qiao)在(zai)清朝《黎平(ping)府(fu)志》中(zhong)就有(you)記載:“天(tian)生(sheng)橋(qiao)崇嚴直跨(kua)兩岸(an),中(zhong)有(you)一硐,雙江(jiang)口諸水徑此(ci),達高(gao)屯(tun)可以行舟。上(shang)則仍然(ran)平(ping)地(di)也,往返(fan)甚(shen)便(bian),不假修(xiu)筑(zhu)之(zhi)力故名(ming)。”對于這種石灰巖地(di)貌自(zi)然(ran)形成(cheng)的(de)(de)天(tian)生(sheng)橋(qiao),明代杰出地(di)理學(xue)家徐霞客在(zai)其《游記》中(zhong)賦予(yu)了(le)它十分正(zheng)確的(de)(de)科學(xue)名(ming)稱(cheng)“石梁”。
高屯天(tian)(tian)(tian)生(sheng)橋(qiao)架在兩(liang)山(shan)之間(jian),跨(kua)度超過150米(mi),橋(qiao)身寬達98米(mi),橋(qiao)體高出(chu)水(shui)面(mian)30多米(mi),而這竟是(shi)(shi)(shi)天(tian)(tian)(tian)設而非人力所為(wei),的(de)確不能不使人咂舌驚奇。對(dui)于這種(zhong)“不假修筑之力”的(de)天(tian)(tian)(tian)生(sheng)橋(qiao),詩(shi)人龔自珍贊日:“人鑿難(nan)施(shi)鬼斧窮,天(tian)(tian)(tian)心穿出(chu)地玲瓏(long),兩(liang)山(shan)壁(bi)立龜(gui)梁(liang)架,巧妙爭(zheng)傳造化工。” 黎(li)平高屯天(tian)(tian)(tian)生(sheng)橋(qiao)不僅宏(hong)偉(wei)壯觀(guan),而且環境幽(you)美。橋(qiao)下河流(liu)由福祿江、五里(li)江、后坡(po)江諸(zhu)水(shui)匯成,逆水(shui)而上數里(li)仍是(shi)(shi)(shi)喀(ka)斯地貌(mao)景(jing)觀(guan);往下一片潺(chan)潺(chan)流(liu)水(shui),分兩(liang)岔繞橋(qiao)門的(de)圓(yuan)形山(shan)巒,至數十(shi)米(mi)處(chu),又(you)融為(wei)一體,依山(shan)傍水(shui),逶迤北(bei)處(chu)2公里(li),注入亮江。橋(qiao)下河水(shui)澄澈(che)清瑩(ying),橋(qiao)四周(zhou)都是(shi)(shi)(shi)奇峰峻石,河兩(liang)岸森林薈萃,十(shi)分幽(you)靜(jing)。從橋(qiao)孔內(nei)順水(shui)下看(kan)呈現一幅天(tian)(tian)(tian)然妙絕的(de)畫卷(juan),使人心曠神(shen)怡。若是(shi)(shi)(shi)一葉輕舟順流(liu)而下,顧盼(pan)轉首,便(bian)可將兩(liang)岸山(shan)光(guang)水(shui)色(se)盡收(shou)眼底。
