都江堰導游詞歡迎詞篇一

那眾所周知，都江堰水利工程是由李冰父子于公元前256年修建的，它位于四川盆地邊緣的岷江中游，今都江堰市城西，距成都60公里左右。它是集防洪、航運、灌溉為一體的水利工程。距今已有2200多年的歷史。它不僅是我國最古老、最偉大的水利工程，也是全世界迄今為止，年代最久遠、唯一留存下來并以無壩引水為特征的宏大水利工程。都江堰的灌溉面積超過1000萬畝。2200多年來，都江堰仍在正常發揮著它的各項社會功用，而與其同時代修建的鄭國渠、靈渠的社會功用卻已經早早的廢弛了，大家就不禁要問，都江堰為什么能數十年、數百年、甚至數千年如一日的灌溉著成都平原，這樣歷久不衰。這其中到底有什么奧秘呢?

其實啊。原因就在于都江堰水利工程修建的科學性，可能大家都知道都江堰水利工程是有魚嘴分水堤、飛沙堰泄洪道、寶瓶口引水口三大主體工程構成，它科學的解決了江水自動分流、自動排沙、控制水量等問題，使成都平原成為“水旱從人，食無荒年，不知饑饉”的天府之國。都江堰之所以能穩穩當當的造福千年，還得益于這三大渠首工程。

首先，讓我們看看魚嘴分水堤的妙用，那顧名思義，是該工程大堤前端形似魚嘴，故而得名，它的主要功能是分水，將上游奔流而下的江水一分為二，左邊稱為外江，俗稱金馬河，是岷江的主流，主要用于排洪，右邊沿山腳的是內江，為人工引水渠道，主要用于灌溉。魚嘴的設置極為巧妙，它充分利用地形地勢巧妙地完成分流引水大的任務，并且在洪水枯水季節不同水位條件下，起著調節水量的作用。春天，也就是枯水季節時，岷江水量小，灌區正值春耕，需要用水，這時岷江主流直入內江，水量約占六成，外江四成，這樣可以保證灌溉，夏季洪水季節時，在彎道動力學原理的作用下，二者的比例會自動的顛倒過來，內江四成，外江六成，使灌區不受水災。二王廟墻壁上刻的治水《三字經》中說的“分四六,平潦旱”就是說的魚嘴這一天然調節分流比例的作用。

除了分水這個功用外，魚嘴還有排沙的重要功用，因其建在岷江大彎道的下方，因而外江處于凸岸，內江處于凹岸。當洪水季節來臨時，水流夾帶的大量沙石到大彎道時，不可避免地形成巨大的漩渦，此時含沙量大，重而沉底的底層水被離心力甩出，與百分之六十的主流一起直沖外江，而含沙量小的表層水被離心力甩到凹岸，沖向內江，魚嘴是二八排沙的，百分之八十外江，百分之二十內江。

魚嘴說完了，現在我們接著看看飛沙堰的功能，飛沙堰位于魚嘴下方1070米處，長200米，高2.15米，是一個看似平凡的工程，其實它的功用卻非常的大，可以毫不夸張的說，它是確保成都平原不受水旱災害的關鍵，它的主要作用是泄洪，即當內江的水量超過寶瓶口流量上限時，把多余的水從這里排到外江，如果遇到特大洪水的情況，飛沙堰還會自動潰堤，讓大量的江水回歸岷江的主流，另一個作用是排沙，剛才說道在魚嘴處已經江百分之八十的沙石排到了外江，剩下的百分之二十到了內江，這些沙石進入內江后并不會全部的流入成都平原。因為飛沙堰在這里起到了排沙的關鍵作用。它會將這百分之二十中的百分之十五的沙石排到外江，這樣就只有百分之五的沙石才從寶瓶口進到成都平原，一般情況下，洪水越大，飛沙堰的排沙功能越強，最高可以達到百分之九十八。這樣就保證了內江水流的通暢。可見飛沙堰的確不簡單。

寶瓶口，是玉壘山伸向岷江的長脊上開的一個口子，是人工鑿成控制內江進水的咽喉。因形如瓶口而得名。寶瓶口是內江水流進入成都平原的通道，它有固定的進水量，不管有多少水流入內江，只要超過了寶瓶口的接納量，它都會一律的拒之口外。從而保證成都平原有足夠的水用于灌溉，同時也不至于遭受洪水災害。說道寶瓶口，就不得不說它的開鑿過程，玉壘山山石堅硬，當時生產工具落后，民工們是用鐵具鑿挖的，工程進度及其緩慢，挖通估計得30年，后來，有個有經驗的老民工建議，應當在巖石上開一些溝槽，然后放上柴火，點燃燃燒，這樣巖石會爆裂開，再用冰冷的岷江水澆灌，在熱脹冷縮的原理作用下，堅硬的玉壘山就不再堅硬了。最后，李冰用了8年的時間打通了玉壘山。在寶瓶口的一側，大家可以看到離堆。因為與玉壘山山體相離而得名。

都江堰的三大主體工程就是這樣工作的。其中不難發現，魚嘴、飛沙堰、寶瓶口的功用是相輔相成的。正是有了這樣的相互作用，都江堰才如此的偉大，它是獨一無二的。“因勢利導”是它治水哲學的精髓，它和現在司空見慣的攔河大壩，一橫一縱，一堵一導代表了截然不同的治水哲學。一個是征服自然，一個是順應自然。都江堰以它不可思議的水利哲學頻頻受到國內外專家的高度贊揚。有關部門統計，中國水庫的平均壽命只有50年，條件較好的美國水庫的平均壽命也不超過320xx年，相形之下，都江堰卻已經存在了2200多年。難怪余秋雨先生會在它的著作中發出這樣的感嘆：我以為中國歷史上最激動人心的工程不是長城，而是都江堰。

青城山位于中國西部四川省都江堰市西南15公里處。因為山上樹木茂盛，四季常青，故歷來享有“青城天下幽”的美譽。

青城山是中國道教的重要發祥地。全山的道教宮觀以天師洞為核心，包括建福宮、上清宮、祖師殿、圓明宮、老君閣、玉清宮、朝陽洞等10余座。建福宮建于唐開元十八年(公元730年)，現存建筑為清代光緒年間 (公元1888年)重建。現有大殿三重，分別奉祀道教名人和諸神，殿內柱上的394字的對聯，被贊為“青城一絕”。天然圖畫坊位于龍居山牌坊崗的山脊上，是一座十角重檐式的亭閣，建于清光緒(公元1875～1920xx年)年間。這里風景優美，游人到此仿佛置身畫中，故將其稱為“天然圖畫”。

這些建筑充分體現了道家追求自然的思想，一般采用按中軸線對稱展開的傳統手法，并依據地形地貌，巧妙地構建各種建筑。建筑裝飾上也反映了道教追求吉祥、長壽和升仙的思想。對于深入研究中國古代的道教哲學思想，有著重要的歷史和藝術價值。

青城山因其的秀麗的自然風光和眾多道教建筑而成為天下名山，自古就是游覽勝地和隱居修練之處，文人墨客們留下了的珍貴“墨寶”，為這座名山增添了豐富的人文景觀。特別是為數眾多的楹聯，不但贊美了青城山的美麗，還頌揚了道教思想、道教經典，表達出對中華民族的人文初祖由衷的敬意，以及對國家興衰、民生榮辱的關注。

都江堰是著名的古代水利工程，位于四川省成都平原西部的岷江上，今都江堰市城西。它處于岷江從山區瀉入成都平原的地方。在都江堰建成以前，岷江江水常泛濫成災。公元前256年，秦國蜀郡太守李冰和他的兒子，吸取前人的治水經驗，率領當地人民興建水利工程。都江堰建成后，成都平原沃野千里，成為“天府之國”，這項工程直到今天還在發揮著作用，被稱為“活的水利博物館”。

都江堰工程包括魚嘴、飛沙堰和寶瓶口三個主要組成部分。魚嘴是在岷江江心修筑的分水堤壩，形似大魚臥伏江中，它把岷江分為內江和外江，內江用于灌溉，外江用于排洪。飛沙堰是在分水堤壩中段修建的泄洪道，洪水期不僅泄洪水，還利用水漫過飛沙堰流入外江水流的漩渦作用，有效地減少了泥沙在寶瓶口前后的淤積。寶瓶口是內江的進水口，形似瓶頸。除了引水，還有控制進水流量的作用。

此外，都江堰一帶還有二王廟、伏龍觀、安瀾索橋等名勝古跡。

二王廟位于岷江右岸的山坡上，前臨都江堰，原為紀念蜀王的望帝祠，齊建武(公元494～498年)時改祀李冰父子，更名為“崇德祠”。宋代(公元960～1279年)以后，李冰父子相繼被皇帝敕封為王，故而后人稱之為“二王廟”。廟內主殿分別供有李冰父子的塑像，并珍藏有治水名言、詩人碑刻等。

伏龍觀位于離堆公園內。傳說李冰治水時曾在這里降服惡龍，現存殿宇三重，前殿正中立有東漢時期(公元25～220xx年)所雕的李冰石像。殿內還有東漢堰工石像、唐代金仙和玉真公主在青城山修道時的遺物——飛龍鼎。

安瀾索橋又名“安瀾橋”、“夫妻橋”。始建于宋代以前。位于都江堰魚嘴之上，被譽為“中國古代五大橋梁”，是都江堰最具特征的景觀。索橋以木排石墩承托，用粗竹纜橫掛江面，上鋪木板為橋面，兩旁以竹索為欄，全長約500米。明末(公元17世紀)毀于戰火。現在的橋為鋼索混凝土樁。

都江堰水利工程以獨特的水利建筑藝術創造了與自然和諧共存的水利形式。它創造了成都平原的水環境，由此孕育了蜀文化繁榮發展的沃土。都江堰不但是世界上惟一具有20xx多年歷史，且至今尚在發揮重要作用的古代水利工程。同時它還是集政治、宗教和建筑精華于一體的珍貴文化遺產。

都江堰位于四川省成都市都江堰市灌口鎮，是中國建設于古代并使用至今的大型水利工程，被譽為“世界水利文化的鼻祖”，是全國著名的旅游勝地。通常認為，都江堰水利工程是由秦國蜀郡太守李冰及其子率眾于公元前256年左右修建的，是全世界迄今為止，年代最久、唯一留存、以無壩引水為特征的宏大水利工程，也是全國重點文物保護單位。風景名勝都江堰水利工程充分利用當地西北高、東南低的地理條件，根據江河出山口處特殊的地形、水脈、水勢，乘勢利導，無壩引水，自流灌溉，使堤防、分水、泄洪、排沙、控流相互依存，共為體系，保證了防洪、灌溉、水運和社會用水綜合效益的充分發揮。

都江堰建成后，成都平原沃野千里，“水旱從人，不知饑饉，時無荒年，謂之天府”。四川的經濟文化有很大發展。其最偉大之處是建堰兩千多年來經久不衰，而且發揮著愈來愈大的效益。都江堰的創建，以不破壞自然資源，充分利用自然資源為人類服務為前提，變害為利。都江堰渠首樞紐主要由魚嘴、飛沙堰、寶瓶口三大主體工程構成。三者有機配合，相互制約，協調運行，引水灌田，分洪減災，具有“分四六，平潦旱”的功效。 最佳旅游時間都江堰全年氣溫較高，年均溫12～20℃，冬暖夏熱，四季不明顯，四季皆適宜旅游。歷史文化都江堰的創建，以不破壞自然資源，充分利用自然資源為人類服務為前提，變害為利，使人、地、水三者高度協合統一，是全世界迄今為止僅存的一項偉大的“生態工程”。

開創了中國古代水利史上的新紀元，標志著中國水利史進入了一個新階段，在世界水利史上寫下了光輝的一章。都江堰水利工程，是中國古代人民智慧的結晶，是中華文化劃時代的杰作。都江堰水利工程。歷經2260年而不衰，是當今世界年代久遠、唯一留存、以無壩引水為特征的宏大水利工程。它是中國古代歷史上最成功的水利杰作，更是古代水利工程沿用至今，“古為今用”、碩果僅存的奇觀。與之興建時間大致相同的古埃及和古巴比侖的灌溉系統，以及中國陜西的鄭國渠和廣西的靈渠，都因滄海變遷和時間的推移，或湮沒、或失效，唯有都江堰獨樹一幟，有興建源遠流長，至今還滋潤著天府之國的萬頃良田。

由都江堰而產生的具有強烈地域色彩的都江堰水文化包括水文學、水文物、水神學等，諸如“二王廟”、“伏龍觀”、“觀景臺”等處的人文景觀;改建魚嘴挖掘出土的東漢李冰石像和“飲水思源”石刻;歌頌李冰父子降龍治水的民間傳說和具有一定宗教神學色彩的祭祀活動;以及由此而產生的祭水、祭神、祭人的詩、詞、書畫的水文學等，形成獨具特色的都江堰水文化。都江堰有塊石碑，上面刻著“深淘灘，低作堰”字樣。

都江堰導游詞歡迎詞篇四

世界古老水利工程之一。位于四川省都江堰市，岷江中游。又稱百大堰、犍尾堰、金堤等。始建于公元前250年,公元1335年正式命名為都江堰。現為中國重點文物保護單位。渠首在灌縣境內，包括“魚嘴”、“金剛堤”、“飛沙堰”和“寶瓶口” 4個主要工程和數以千計的渠道與分堰。岷江水流至玉壘山下時，被“魚嘴”工程分成兩股，南側稱外江，是岷江正流，以排泄洪水為主，兼有灌溉之利;北側為內江，又稱都江堰，長約160公里,以灌溉農田為主。其下游分汊為走馬河、柏條河、蒲陽河等渠系。其中，走馬河和柏條河的一部分尾水，在成都以南入府河后，再重返岷江正流。“魚嘴”后面是由巨大的鵝卵石筑成的內外“金剛堤”，與“魚嘴”連成一體，是分水工程的主要部分。“金剛堤”后是“飛沙堰”，以排洪排沙為主，使內江江水保持適當的水量。堰后即為離堆巨崖，崖下就是“寶瓶口”工程。都江堰是中國古代勞動人民利用成都平原上河流走向與等高線相垂直的天然地形條件而建造的。中華人民共和國成立后,對都江堰灌區工程進行了徹底改造和擴展,使灌區面積由原來的14縣市，17.3萬多公頃農田，迅速擴大到30縣市，57.3萬多公頃農田。

都江堰坐落于四川省都江堰市城西，位于成都平原西部的岷江上。都江堰水利工程建于公元前256年，是全世界迄今為止，年代最久、唯一留存、以無壩引水為特征的宏大水利工程。屬全國重點文物保護單位。都江堰附近景色秀麗，文物古跡眾多，主要有伏龍觀、二王廟、安瀾索橋、玉壘關、離堆公園、玉壘山公園和靈巖寺等。

都江堰水利工程由創建時的魚嘴分水堤、飛沙堰溢洪道、寶瓶口引水口三大主體工程和百丈堤、人字堤等附屬工程構成。科學地解決了江水自動分流、自動排沙、控制進水流量等問題，消除了水患，使川西平原成為“水旱從人”的“天府之國”。兩千多年來，一直發揮著防洪灌溉作用。截至1998年，都江堰灌溉范圍已達40余縣，灌溉面積達到66.87萬公頃。

魚嘴是修建在江心的分水堤壩，把洶涌的岷江分隔成外江和內江，外江排洪，內江引水灌溉。飛沙堰起瀉洪、排沙和調節水量的作用。寶瓶口控制進水流量，因口的形狀如瓶頸，故稱寶瓶口。內江水經過寶瓶口流入川西平原灌溉農田。從玉壘山截斷的山丘部分，稱為“離堆”。

都江堰水利工程充分利用當地西北高、東南低的地理條件，根據江河出山口處特殊的地形、水脈、水勢，乘勢利導，無壩引水，自流灌溉，使堤防、分水、泄洪、排沙、控流相互依存，共為體系，保證了防洪、灌溉、水運和社會用水綜合效益的充分發揮。都江堰建成后，成都平原沃野千里，“水旱從人，不知饑饉，時無荒年，謂之天府”。四川的經濟文化有很大發展。其最偉大之處是建堰兩千多年來經久不衰，而且發揮著愈來愈大的效益。都江堰的創建，以不破壞自然資源，充分利用自然資源為人類服務為前提，變害為利，使人、地、水三者高度協調統一。

都江堰工程至今猶存，仍發揮著工作。隨著科學技術的發展和灌區范圍的擴大，從1936年開始，逐步改用混凝土漿砌卵石技術對渠首工程進行維修、加固，增加了部分水利設施，古堰的工程布局和“深淘灘、低作堰”，“乘勢利導、因時制宜”，“遇灣截角、逢正抽心”等治水方略沒有改變，都江堰水利工程成為世界最佳水資源利用的典范。水利專家仔細觀看了整個工程的設計后，都對它的高度的科學水平驚嘆不止。比如飛沙堰的設計就是很好地運用了回旋流的理論。這個堰，平時可以引水灌溉，洪水時則可以排水入外江，而且還有排砂石的作用，有時很大的石塊也可以從堰上滾走。當時沒有水泥，這么大的工程都是就地取材，用竹籠裝卵石作堰，費用較省，效果顯著。

都江堰這一帶風景優美，有不少名勝古跡，又是一處十分理想的游覽勝地。都江堰一帶有二王廟、伏龍觀、安瀾索橋等名勝古跡。

二王廟位于岷江右岸的山坡上，前臨都江堰，原為紀念蜀王的望帝祠，齊建武(公元494～498年)時改祀李冰父子，更名為“崇德祠”。宋代(公元960～1279年)以后，李冰父子相繼被皇帝敕封為王，故而后人稱之為“二王廟”。廟內主殿分別供有李冰父子的塑像，并珍藏有治水名言、詩人碑刻等。

伏龍觀位于離堆公園內。傳說李冰治水時曾在這里降服惡龍，現存殿宇三重，前殿正中立有東漢時期(公元25～220xx年)所雕的李冰石像。殿內還有東漢堰工石像、唐代金仙和玉真公主在青城山修道時的遺物——飛龍鼎。

安瀾索橋又名“安瀾橋”、“夫妻橋”。始建于宋代以前。位于都江堰魚嘴之上，被譽為“中國古代五大橋梁”，是都江堰最具特征的景觀。索橋以木排石墩承托，用粗竹纜橫掛江面，上鋪木板為橋面，兩旁以竹索為欄，全長約500米。明末(公元17世紀)毀于戰火。現在的橋為鋼索混凝土樁。

都江堰不僅是舉世聞名的中國古代水利工程，也是著名的風景名勝區。1982年，都江堰作為四川青城山-都江堰風景名勝區的重要組成部分，被國務院批準列入第一批國家級風景名勝區名單。20xx年5月8日，成都市青城山--都江堰旅游景區經國家旅游局正式批準為國家5a級旅游景區。

根據聯合國《保護世界文化和自然遺產公約》第一條第二款有關文化遺產定義的規定：“建筑物：從歷史、藝術或科學角度看在建筑式樣、分布均勻或與環境景色結合方面具有突出的普遍意義價值的單體或連接的建筑群”。都江堰水利工程以歷史悠久、規模宏大、布局合理、運行科學，與環境和諧結合，在歷史和科學方面具有突出的普遍價值，20xx年聯合國世界遺產委員會第24屆大會上都江堰被確定為世界文化遺產。

編輯本段名稱由來

秦蜀郡太守李冰建堰初期，都江堰名稱叫“湔堋”，這是因為都江堰旁的玉壘山，秦漢以前叫“湔山”，而那時都江堰周圍的主要居住民族是氐羌人，他們把堰叫做“堋”，都江堰就叫“湔堋”。

三國蜀漢時期，都江堰地區設置都安縣，因縣得名，都江堰稱“都安堰”。同時，又叫“金堤”，這是突出魚嘴分水堤的作用，用堤代堰作名稱。

唐代，都江堰改稱為“楗尾堰”。因為當時用以筑堤的材料和辦法，主要是“破竹為籠，圓徑三尺，以石實中，累而壅水”，即用竹籠裝石，稱為“楗尾”。

直到宋代，在宋史中，才第一次提到都江堰：“永康軍歲治都江堰，籠石蛇決江遏水，以灌數郡田。”

為什么稱都江堰，都江是哪條江呢?《蜀水考》說：“府河，一名成都江，有二源，即郫江，流江也。”流江是檢江的另一種稱呼，成都平原上的府河即郫江，南河即檢江，它們的上游，就是都江堰內江分流的柏條河和走馬河。《括地志》說：“都江即成都江”。從宋代開始，把整個都江堰水利系統工程概括起來，叫都江堰，才較為準確地代表了整個水利工程系統，一直沿用至今。

one of the ancient water conservancy project in the world. is located in dujiangyan city, sichuan province, the middle reaches of minjiang river. also known as the one hundred big weir, weir jian tail, gold dike, etc. began in 250 bc, in 250 officially named the town of dujiangyan. now the capital of china's key cultural relics protection units. feeding in county territory, including the "fish mouth", "jin gangdi", "flying sand dam" and "baopingkou" four major projects and thousands of channels and weir. minjiang river water to which the foot, be "fish mouth" the project is spanided into two shares, said the south river, minjiang river flow, is give priority to with flood discharge, both of the irrigation; the north inner river, also known as the town of dujiangyan, about 160 kilometers long, give priority to in order to irrigate their fields. its downstream branching for cook's river, baitiaohe, puyanghe canal system. among them, take up a part of the river and baitiaohe tail water, in the south of chengdu into fuhe, again to return to the minjiang river is flowing.

fish mouth is built in jiangxin water dam, the minjiang river surge is spanided into outer and neijiang, jiang outside having, jiang baopingkou water spanersion irrigation. fly sand dam up xie hong, desilting and adjust the action of water. baopingkou control water flow, the shape of the mouth for such as bottlenecks, therefore calls baopingkou. in the river after baopingkou into the western sichuan plain irrigation farmland. from the hills hill part of truncation, which is called "from the heap.

dujiangyan water conservancy project makes full use of local geographical conditions of high northwest, southeast low, according to the mountain rivers in special terrain, water vein, water potential, return pattern, no dam spanersion, gravity irrigation, the embankment, water, water, sand, curtains on interdependence, for system, to ensure the water flood control, irrigation, water transportation and social comprehensive benefits into full play. after the completion of dujiangyan, the chengdu plain lies thousands of miles, " from people, do not know famine, when no famine," tianfu ". culture has a great development of the economy in sichuan province. its greatest dam was built two thousand years enduring, and it plays a more and more big. dujiangyan to create, in order to does not destroy the natural resources, make full use of natural resources for human services for the premise, change for profit, make the person, the land, water three highly harmonious and unified.

dujiangyan project remain, so far still plays a job. with the enlargement of the scope of the development of science and technology and irrigation area, begin from 1936, gradually switch to slurry concrete build by laying bricks or stones pebble technology of ancient project for repair, reinforcement, add some of the water conservancy facilities, the engineering layout and ancient weir are crowded "deep, low weir tao beach", "return pattern, since the", "cutting angle, every heart is pumping in bay" and other valuable hasn't changed, dujiangyan water conservancy project to become the world's best model of water resource utilization. water conservancy experts, after carefully watched the whole project design of its height more than the scientific level of marvel. such as sand weir design is a good use of the theory of swirling flow. the weir, at ordinary times can be irrigated, flooding can drain into the river, but also the role of sand and gravel, sometimes big stones can roll away from the weir. there were no cement, for such a big engineering is use local materials, using bamboo cages packed pebble as weir, expenses in province, effect is remarkable.

dujiangyan scenic in this area, there are many places of interest, it is an ideal tourist attraction. dujiangyan one with two kings temple, fulong view, peaceful bridge such as places of historic interest.

edit this section name origin

early qin shu satrap li bingjian weir, the dujiangyan name call "jian which", this is because the dujiangyan which near the mountain, qin and han dynasties ago called "jian mountain", and then the dujiangyan di qiang is the main living national people around, they called the dam "which", dujiangyan is called "jian which".

three kingdoms period, dujiangyan area set douan map, because the county is named, dujiangyan said "float weir. at the same time, also called "bank of gold", it is highlight the role of yuzui water-spaniding dike, name generation embankment dam.

the tang dynasty, dujiangyan renamed "jian tail dam". because at that time to the embankment material and method, main is "cut for bamboo cage, three feet, circle diameter to shi shi, tired and backwater", which uses bamboo cages with stone, known as the "jian tail".

until the song dynasty, in the highly, dujiangyan first mentioned: "yongkang army at the age of dujiangyan, stone cage snake river stem water, with several county irrigation."

why said dujiangyan, what's the doujiang jiang? "shu water test" said: "fuhe, chengdu, a river, there are two source, namely pi river, flow jiang also." flow is another call check jiang, jiang on the chengdu plain fuhe pi river, south river river, namely their upstream, dujiangyan is neijiang shunt baitiaohe and take up the river. "including topography," said: "doujiang chengdu river". since the song dynasty, the whole project in summary, the dujiangyan irrigation system called dujiangyan, to more accurately represent the entire system of water conservancy projects, has been in use today.
