1981年7月9—14日,長江(jiang)上(shang)游(you)(you)四川盆地(di)廣(guang)大地(di)區發生了歷(li)史上(shang)罕見的大面積連續(xu)6天暴(bao)雨(yu),雨(yu)區主要集中(zhong)在嘉陵江(jiang)干流(liu)中(zhong)游(you)(you)、涪江(jiang)中(zhong)下(xia)游(you)(you)、沱江(jiang)上(shang)中(zhong)游(you)(you)以(yi)及岷江(jiang)與渠江(jiang)中(zhong)游(you)(you)部分(fen),致使長江(jiang)上(shang)游(you)(you)干流(liu)重慶(qing)至宜(yi)昌(chang)河(he)段出現(xian)了當(dang)時建國以(yi)后或歷(li)史上(shang)少(shao)見的洪(hong)水(shui)。
重慶(qing)寸(cun)灘站(zhan)洪(hong)(hong)峰流量高達(da)85700立方米每(mei)秒,成為當時20世紀以后的最大洪(hong)(hong)水。由于山洪(hong)(hong)暴發,洪(hong)(hong)水泛濫,導致了干支流兩岸人(ren)民生命財產和(he)工農業生產的嚴重損(sun)失(shi),受(shou)(shou)災(zai)人(ren)口達(da)1500多(duo)萬人(ren),150萬人(ren)無家可(ke)歸,受(shou)(shou)淹(yan)耕地1300多(duo)萬畝,洪(hong)(hong)災(zai)造成的直接經濟損(sun)失(shi)約20億元。
四(si)(si)川(chuan)(chuan)盆(pen)(pen)地(di)(di)屬亞熱帶氣(qi)候,雨(yu)量(liang)充(chong)沛,年(nian)雨(yu)量(liang)900—1200毫米,基本上由盆(pen)(pen)緣山地(di)(di)向盆(pen)(pen)地(di)(di)腹部(bu)遞減,雨(yu)量(liang)集(ji)中(zhong)在汛期,5—10月(yue)雨(yu)量(liang)約占全年(nian)雨(yu)量(liang)的(de)80%,其中(zhong)暴(bao)雨(yu)多發(fa)生在7、8兩月(yue),四(si)(si)川(chuan)(chuan)盆(pen)(pen)地(di)(di)西部(bu)峨嵋山、川(chuan)(chuan)東北大巴山南麓為長江(jiang)(jiang)(jiang)流(liu)域(yu)主(zhu)要(yao)暴(bao)雨(yu)區(qu)。四(si)(si)川(chuan)(chuan)盆(pen)(pen)地(di)(di)洪(hong)水(shui)(shui)(shui)(shui)災害(hai)頻(pin)繁,嘉陵江(jiang)(jiang)(jiang)于流(liu)合(he)川(chuan)(chuan)縣(xian)近(jin)200年(nian)間(jian)大水(shui)(shui)(shui)(shui)淹城(cheng)記載就有(you)13次(ci)之多,涪江(jiang)(jiang)(jiang)下游(you)遂寧縣(xian)近(jin)百年(nian)來也被淹過8次(ci)。四(si)(si)川(chuan)(chuan)省地(di)(di)形復雜(za),局部(bu)地(di)(di)區(qu)如—二條水(shui)(shui)(shui)(shui)系(xi)(xi)發(fa)生大洪(hong)水(shui)(shui)(shui)(shui)的(de)機會較多,而岷江(jiang)(jiang)(jiang)、沱江(jiang)(jiang)(jiang)、嘉陵江(jiang)(jiang)(jiang)水(shui)(shui)(shui)(shui)系(xi)(xi)同時發(fa)生大洪(hong)水(shui)(shui)(shui)(shui)的(de)機會較少,1981年(nian)7月(yue)暴(bao)雨(yu)洪(hong)水(shui)(shui)(shui)(shui)則屬于這種類型,歷史(shi)上與其相類似的(de)有(you)1840年(nian)、1870年(nian)洪(hong)水(shui)(shui)(shui)(shui)。
1981年7月9日(ri)(ri)(ri)(ri)到14日(ri)(ri)(ri)(ri),長(chang)江(jiang)上游四(si)川盆地腹地出現大(da)(da)(da)范(fan)(fan)圍的(de)(de)暴(bao)(bao)雨(yu)(yu)(yu)(yu)(yu)歷時1天。11—13日(ri)(ri)(ri)(ri)三(san)天雨(yu)(yu)(yu)(yu)(yu)量集中(zhong),強(qiang)度大(da)(da)(da)、范(fan)(fan)圍廣。其中(zhong)以(yi)12日(ri)(ri)(ri)(ri)11時至(zhi)13日(ri)(ri)(ri)(ri)11時的(de)(de)雨(yu)(yu)(yu)(yu)(yu)強(qiang)最(zui)大(da)(da)(da)。六天暴(bao)(bao)雨(yu)(yu)(yu)(yu)(yu)由9—11日(ri)(ri)(ri)(ri)、12—14日(ri)(ri)(ri)(ri)兩次降雨(yu)(yu)(yu)(yu)(yu)構成。9—11日(ri)(ri)(ri)(ri)由東西向(xiang)切變造成東北(bei)(bei)—西南向(xiang)暴(bao)(bao)雨(yu)(yu)(yu)(yu)(yu)帶。雨(yu)(yu)(yu)(yu)(yu)區主要(yao)分布(bu)在岷、沱、涪(fu)、嘉四(si)江(jiang)的(de)(de)中(zhong)上游。三(san)日(ri)(ri)(ri)(ri)總(zong)降雨(yu)(yu)(yu)(yu)(yu)量在105毫(hao)(hao)米(mi)以(yi)上的(de)(de)暴(bao)(bao)雨(yu)(yu)(yu)(yu)(yu)中(zhong)心(xin)有4個(ge),其中(zhong)安寧橋站雨(yu)(yu)(yu)(yu)(yu)量206.1毫(hao)(hao)米(mi)為最(zui)大(da)(da)(da)。三(san)日(ri)(ri)(ri)(ri)雨(yu)(yu)(yu)(yu)(yu)量大(da)(da)(da)于100毫(hao)(hao)米(mi)的(de)(de)籠(long)(long)罩(zhao)(zhao)面積為15048平(ping)方(fang)公里。12一14日(ri)(ri)(ri)(ri)由北(bei)(bei)槽南渦的(de)(de)天氣形勢繼續造成在岷、沱、涪(fu)、嘉四(si)江(jiang)上中(zhong)游大(da)(da)(da)面積暴(bao)(bao)雨(yu)(yu)(yu)(yu)(yu)或(huo)特大(da)(da)(da)暴(bao)(bao)雨(yu)(yu)(yu)(yu)(yu)。三(san)日(ri)(ri)(ri)(ri)總(zong)雨(yu)(yu)(yu)(yu)(yu)量超過300毫(hao)(hao)米(mi)的(de)(de)暴(bao)(bao)雨(yu)(yu)(yu)(yu)(yu)中(zhong)心(xin)有5個(ge),其中(zhong)位于嘉陵(ling)江(jiang)中(zhong)游的(de)(de)上寺(si)站439.7毫(hao)(hao)米(mi)為最(zui)大(da)(da)(da)。暴(bao)(bao)雨(yu)(yu)(yu)(yu)(yu)籠(long)(long)罩(zhao)(zhao)面積遠大(da)(da)(da)于9—11日(ri)(ri)(ri)(ri)降雨(yu)(yu)(yu)(yu)(yu)過程。三(san)日(ri)(ri)(ri)(ri)雨(yu)(yu)(yu)(yu)(yu)量大(da)(da)(da)于100毫(hao)(hao)米(mi)的(de)(de)籠(long)(long)罩(zhao)(zhao)面積為103480平(ping)方(fang)公里。
7月12日為降雨(yu)最集中(zhong)(zhong)的(de)一(yi)天(tian),范圍也廣,雨(yu)帶呈東(dong)北—西南向。日雨(yu)量(liang)(liang)超過200毫米(mi)(mi)的(de)有4個站(zhan)(zhan),籠罩面(mian)積3700平方公(gong)里(li),暴雨(yu)中(zhong)(zhong)心(xin)上寺站(zhan)(zhan)的(de)日雨(yu)量(liang)(liang)為345.8毫米(mi)(mi)。7月13日雨(yu)區范圍增大(da),大(da)于(yu)50毫米(mi)(mi)的(de)籠罩面(mian)積137440平方公(gong)里(li)。但強度有所(suo)減弱,日雨(yu)量(liang)(liang)超過200毫米(mi)(mi)的(de)有9個站(zhan)(zhan),籠罩面(mian)積1580平方公(gong)里(li),暴雨(yu)中(zhong)(zhong)心(xin)在嘉陵(ling)江九龍山站(zhan)(zhan),日雨(yu)量(liang)(liang)為242.4毫米(mi)(mi)。12一(yi)13日兩日降雨(yu)量(liang)(liang)占六日雨(yu)量(liang)(liang)的(de)80—90%。
7月(yue)9—14日六天(tian)暴雨(yu)(yu)全過(guo)程,雨(yu)(yu)區(qu)分(fen)布(bu)在雅礱(long)江(jiang)(jiang)(jiang)下(xia)(xia)游(you)、岷江(jiang)(jiang)(jiang)中(zhong)下(xia)(xia)游(you)、大(da)渡(du)河下(xia)(xia)游(you)、青衣江(jiang)(jiang)(jiang)、沱江(jiang)(jiang)(jiang)、嘉(jia)陵(ling)江(jiang)(jiang)(jiang)、渠江(jiang)(jiang)(jiang)、涪江(jiang)(jiang)(jiang)等地(di)區(qu)。暴雨(yu)(yu)中(zhong)心超過(guo)400毫米(mi)(mi)的有(you)(you)10個站,分(fen)布(bu)在沱江(jiang)(jiang)(jiang)上游(you)、涪江(jiang)(jiang)(jiang)中(zhong)游(you)、嘉(jia)陵(ling)江(jiang)(jiang)(jiang)中(zhong)游(you),范(fan)圍達(da)2600平方(fang)公里,最大(da)暴雨(yu)(yu)中(zhong)心在嘉(jia)陵(ling)江(jiang)(jiang)(jiang)中(zhong)游(you)的上寺站,雨(yu)(yu)量(liang)489.6毫米(mi)(mi)。六天(tian)雨(yu)(yu)量(liang)大(da)于300毫米(mi)(mi)的籠罩面積(ji)近2萬(wan)平方(fang)公里,大(da)于100毫米(mi)(mi)的籠罩面積(ji)達(da)17多平方(fang)公里。籠罩面積(ji)之(zhi)廣,居長(chang)江(jiang)(jiang)(jiang)上游(you)有(you)(you)實測資料的首位;特(te)別(bie)是(shi)大(da)暴雨(yu)(yu)發生(sheng)在盆地(di)腹部,更為少(shao)見。
1981年(nian)7月初起至洪水(shui)(shui)發生前,岷江、沱江、嘉陵(ling)江等水(shui)(shui)系幾(ji)乎每天都有(you)降雨,其(qi)中(zhong)1—4日為一次大(da)面積的(de)暴雨過程。由(you)于(yu)暴雨連(lian)綿不斷(duan),使(shi)流域(yu)內前期土壤含水(shui)(shui)量比較大(da),各水(shui)(shui)系的(de)底水(shui)(shui)也較高。7月9日開始(shi)此此次降雨后(hou),各江上游相繼于(yu)11—12日開始(shi)漲水(shui)(shui)。
岷江(jiang)處于此次暴(bao)雨區(qu)邊緣,降雨集(ji)中在中游成(cheng)都(dou)平原。控制站高場于14日出現洪峰(feng),洪峰(feng)流量25900立方(fang)米每秒,呈雙(shuang)峰(feng)型,小于實測最(zui)大年份1961年6月的(de)34100立方(fang)米每秒,僅為15年間(jian)的(de)最(zui)大值。
沱江上游處于鹿頭山(shan)暴雨區,金堂(tang)三皇廟站洪(hong)(hong)峰流(liu)量(liang)達81l0立(li)方(fang)米每(mei)(mei)(mei)秒,超過了歷史(shi)最大(da)洪(hong)(hong)水的(de)1840年(7730立(li)方(fang)米每(mei)(mei)(mei)秒),金堂(tang)縣(xian)全城被淹。金堂(tang)以(yi)下區間暴雨集中。控制站傘家灣15日出現洪(hong)(hong)峰流(liu)量(liang),高達15200立(li)方(fang)米每(mei)(mei)(mei)秒,為建(jian)國以(yi)后(hou)的(de)最大(da)洪(hong)(hong)水,與1948年洪(hong)(hong)水(16200立(li)方(fang)米每(mei)(mei)(mei)秒)相(xiang)近,當時(shi)居1898年以(yi)后(hou)的(de)第四位。
嘉陵江處于(yu)此次暴雨中(zhong)心(xin)。干流金(jin)銀(yin)臺以上暴雨集中(zhong),強度大,各(ge)支流洪(hong)(hong)水遭遇,金(jin)銀(yin)臺14日(ri)出現洪(hong)(hong)峰流量(liang)(liang)31000立方米每(mei)秒(miao),超(chao)過了歷(li)史最大的1903年(2700立方米每(mei)秒(miao)),致使下游閬中(zhong)、南部、南充等縣(xian)市(shi)大范圍(wei)被(bei)淹沒,下游控制站武勝15日(ri)出現洪(hong)(hong)峰流量(liang)(liang)28900立方米每(mei)秒(miao)。
西支涪江上中游處于暴(bao)雨的第二中心,射洪(hong)(hong)14日洪(hong)(hong)峰流量25700立方(fang)米(mi)(mi)每秒(miao),超(chao)過1954年實測(ce)最大洪(hong)(hong)水,與1945年洪(hong)(hong)水(26200立方(fang)米(mi)(mi)每秒(miao))相(xiang)近。下游控制站小河壩15日洪(hong)(hong)峰流量28700立方(fang)米(mi)(mi)每秒(miao),超(chao)過了1953年、1945年洪(hong)(hong)水,當時(shi)為1870年(29200立方(fang)米(mi)(mi)每秒(miao))以后的最大值。
東支渠(qu)江處于暴雨邊緣,控制(zhi)站羅渡溪16日洪(hong)峰流量為14800立方米每秒,僅屬一(yi)般洪(hong)水。
嘉(jia)陵江(jiang)干流(liu)(liu)洪(hong)(hong)峰與渠江(jiang)洪(hong)(hong)峰遭遇,加上涪江(jiang)洪(hong)(hong)水的(de)后部,致使嘉(jia)陵江(jiang)控制站(zhan)北碚于(yu)16日出現洪(hong)(hong)峰流(liu)(liu)量高達(da)44800立方(fang)米每秒(miao),大(da)大(da)超過了建(jian)國以(yi)后實測最大(da)的(de)1975年洪(hong)(hong)水(37100立方(fang)米每秒(miao)),當時為1870年以(yi)后的(de)第三大(da)洪(hong)(hong)水(1870年為57300、1903年為53300立方(fang)米每秒(miao))。
