汕頭市潮(chao)南(nan)區(qu)較大(da)的水(shui)庫——秋風(feng)水(shui)庫,位于區(qu)境大(da)南(nan)山北麓,是練(lian)江(jiang)最大(da)支流兩英河上游控制性(xing)水(shui)庫。庫水(shui)面縱橫3公(gong)里,控制集(ji)雨(yu)面積105平方公(gong)里,總庫容(rong)6384萬立(li)(li)方米(mi)。現土壩高28米(mi)、面寬6米(mi)、全長(chang)2049米(mi);泄(xie)洪閘2座,最大(da)泄(xie)洪流量452立(li)(li)方米(mi)每秒。
秋風(feng)嶺(ling)水(shui)庫(ku)位(wei)于(yu)潮南區(qu)西南部,因處(chu)原秋風(feng)嶺(ling)村(已移)北側(ce)而得名。建成于(yu)1959年11月,是汕(shan)頭(tou)市大的(de)(de)一宗以(yi)攔(lan)洪(hong)蓄水(shui)為主,控制(zhi)集雨(yu)面(mian)積105.1平(ping)方公里(含上游(you)(you)紅場水(shui)庫(ku)集雨(yu)面(mian)積),總庫(ku)容6903萬(wan)立方米,兼顧灌溉、供(gong)水(shui)、發(fa)(fa)(fa)電等綜(zong)合(he)利用的(de)(de)中型水(shui)庫(ku),建成以(yi)來,有效地治理(li)了練江流域的(de)(de)水(shui)旱(han)災害,解(jie)決(jue)了下游(you)(you)10.2萬(wan)畝農(nong)田灌溉和6個鎮近50萬(wan)人口的(de)(de)飲水(shui)問題(ti),促進了工農(nong)業生產的(de)(de)發(fa)(fa)(fa)展(zhan)。作為治理(li)練江水(shui)旱(han)災害的(de)(de)主要骨干(gan)工程,40多(duo)年來發(fa)(fa)(fa)揮著(zhu)攔(lan)洪(hong)蓄水(shui)、發(fa)(fa)(fa)電、灌溉、供(gong)水(shui)等綜(zong)合(he)效益。
歷史上(shang)兩(liang)英(ying)河中下游(you)兩(liang)岸(an)水旱災害頻繁,降100多(duo)毫米暴雨,洪水往往沖決堤(di)防,并瀉入練江(jiang)平(ping)原泛濫;遇旱則(ze)上(shang)游(you)源(yuan)流(liu)枯(ku)竭,加上(shang)練江(jiang)咸潮上(shang)涌而(er)致旱咸為害;歷代的爭水械(xie)斗,更是(shi)屢見不鮮。
中華人(ren)民(min)共和國成立(li)后(hou),群(qun)(qun)眾(zhong)迫切要(yao)(yao)求(qiu)建(jian)(jian)設(she)水(shui)(shui)(shui)庫(ku)(ku),人(ren)民(min)政府把它列為議事日程(cheng),多(duo)次(ci)組織勘測(ce)。1952年(nian)(nian)(nian)(nian)土改時即已預留移民(min)房屋與(yu)耕地;1956年(nian)(nian)(nian)(nian)6月(yue),縣(xian)(xian)(xian)黨代會通過建(jian)(jian)設(she)秋(qiu)(qiu)風(feng)(feng)(feng)水(shui)(shui)(shui)庫(ku)(ku)的(de)決議,并(bing)成立(li)以郭春(chun)為主(zhu)任(縣(xian)(xian)(xian)委第一(yi)(yi)書記兼(jian))的(de)“籌建(jian)(jian)委員會”;1957年(nian)(nian)(nian)(nian)開展庫(ku)(ku)區(qu)移民(min)遷(qian)安工(gong)(gong)(gong)(gong)(gong)作;1958年(nian)(nian)(nian)(nian)7月(yue),工(gong)(gong)(gong)(gong)(gong)程(cheng)正(zheng)式開工(gong)(gong)(gong)(gong)(gong)。由兩(liang)英、司馬浦、峽山(shan)、臚崗(gang)、和平(ping)、陳店(dian)、銅盂等(deng)一(yi)(yi)萬(wan)(wan)多(duo)民(min)工(gong)(gong)(gong)(gong)(gong)上(shang)工(gong)(gong)(gong)(gong)(gong)地,實行(xing)三(san)班制(zhi)日夜施工(gong)(gong)(gong)(gong)(gong)。當時縣(xian)(xian)(xian)內大批工(gong)(gong)(gong)(gong)(gong)程(cheng)同(tong)時上(shang)馬,人(ren)力物資極度緊缺,但受益(yi)(yi)(yi)區(qu)群(qun)(qun)眾(zhong)表現極大積極性,一(yi)(yi)切服從水(shui)(shui)(shui)庫(ku)(ku)建(jian)(jian)設(she)需要(yao)(yao)。1959年(nian)(nian)(nian)(nian)9月(yue)12日的(de)臺風(feng)(feng)(feng)暴雨(yu),洪(hong)水(shui)(shui)(shui)猛漲至(zhi)38.38米(mi)高(gao)程(cheng),時土壩(ba)(ba)頂高(gao)程(cheng)只達(da)40.06米(mi),風(feng)(feng)(feng)浪沖濺過壩(ba)(ba)頂,4000多(duo)干部(bu)群(qun)(qun)眾(zhong)不顧家(jia)(jia)中受災,頂風(feng)(feng)(feng)冒雨(yu)搶險護壩(ba)(ba),避免(mian)一(yi)(yi)場(chang)(chang)(chang)垮壩(ba)(ba)巨災。1959年(nian)(nian)(nian)(nian)10月(yue)完成土壩(ba)(ba),又組織2萬(wan)(wan)多(duo)民(min)工(gong)(gong)(gong)(gong)(gong)進(jin)行(xing)灌(guan)區(qu)渠道工(gong)(gong)(gong)(gong)(gong)程(cheng)配套(tao),至(zhi)1960年(nian)(nian)(nian)(nian)夏,完成100多(duo)公里的(de)干、支渠道配套(tao)。在水(shui)(shui)(shui)庫(ku)(ku)建(jian)(jian)成以后(hou)的(de)40多(duo)年(nian)(nian)(nian)(nian)間,水(shui)(shui)(shui)庫(ku)(ku)多(duo)次(ci)進(jin)行(xing)加(jia)固、擴建(jian)(jian)與(yu)配套(tao),主(zhu)要(yao)(yao)有1964—1965年(nian)(nian)(nian)(nian),建(jian)(jian)成壩(ba)(ba)后(hou)水(shui)(shui)(shui)電(dian)(dian)(dian)站供內澇地區(qu)電(dian)(dian)(dian)動排(pai)灌(guan)用(yong)電(dian)(dian)(dian);水(shui)(shui)(shui)庫(ku)(ku)擴建(jian)(jian),土壩(ba)(ba)加(jia)高(gao)2米(mi)、面(mian)(mian)加(jia)寬4米(mi)以及(ji)灌(guan)區(qu)全面(mian)(mian)改建(jian)(jian)加(jia)固渠系(xi)與(yu)建(jian)(jian)筑物,使灌(guan)區(qu)達(da)10.2萬(wan)(wan)畝、水(shui)(shui)(shui)庫(ku)(ku)校核(he)標準達(da)200年(nian)(nian)(nian)(nian)一(yi)(yi)遇。1975—1976年(nian)(nian)(nian)(nian),將(jiang)上(shang)金溪、利陂等(deng)水(shui)(shui)(shui)庫(ku)(ku)27平(ping)方公里區(qu)間洪(hong)水(shui)(shui)(shui),截(jie)引入秋(qiu)(qiu)風(feng)(feng)(feng)水(shui)(shui)(shui)庫(ku)(ku),通過圓(yuan)山(shan)泄洪(hong)閘排(pai)出南海(hai);上(shang)游(you)興建(jian)(jian)紅(hong)場(chang)(chang)(chang)水(shui)(shui)(shui)庫(ku)(ku),使秋(qiu)(qiu)風(feng)(feng)(feng)安全標準達(da)千(qian)(qian)年(nian)(nian)(nian)(nian)一(yi)(yi)遇校核(he)。40多(duo)年(nian)(nian)(nian)(nian)來,累(lei)(lei)計(ji)(不包括(kuo)南山(shan)截(jie)洪(hong)與(yu)紅(hong)場(chang)(chang)(chang)工(gong)(gong)(gong)(gong)(gong)程(cheng))完成土方340多(duo)萬(wan)(wan)立(li)萬(wan)(wan)米(mi)、石(shi)方11.5萬(wan)(wan)立(li)方米(mi),投放勞(lao)力960多(duo)萬(wan)(wan)工(gong)(gong)(gong)(gong)(gong)日,建(jian)(jian)成這座(zuo)多(duo)種(zhong)效用(yong)的(de)樞紐工(gong)(gong)(gong)(gong)(gong)程(cheng),主(zhu)要(yao)(yao)效益(yi)(yi)(yi):控(kong)制(zhi)區(qu)間105.1平(ping)方公里的(de)山(shan)洪(hong)直接(jie)排(pai)出南海(hai)(占本(ben)縣(xian)(xian)(xian)練江流域(yu)山(shan)地面(mian)(mian)積的(de)三(san)分之一(yi)(yi)),解除兩(liang)英河洪(hong)災,大大減輕練江澇災,最(zui)大灌(guan)溉10萬(wan)(wan)畝;回收上(shang)游(you)紅(hong)場(chang)(chang)(chang)3級(ji)水(shui)(shui)(shui)電(dian)(dian)(dian)發電(dian)(dian)(dian)尾水(shui)(shui)(shui),改善壩(ba)(ba)后(hou)電(dian)(dian)(dian)站發電(dian)(dian)(dian),成為縣(xian)(xian)(xian)電(dian)(dian)(dian)網發電(dian)(dian)(dian)主(zhu)力,累(lei)(lei)計(ji)4個梯級(ji)電(dian)(dian)(dian)站從投運至(zhi)今已發電(dian)(dian)(dian)10223.4萬(wan)(wan)千(qian)(qian)瓦(wa)時。此(ci)時還供縣(xian)(xian)(xian)魚苗場(chang)(chang)(chang)、養鰻場(chang)(chang)(chang)、布廠等(deng)生(sheng)(sheng)產用(yong)水(shui)(shui)(shui),至(zhi)1990年(nian)(nian)(nian)(nian),累(lei)(lei)計(ji)提供生(sheng)(sheng)產與(yu)生(sheng)(sheng)活(huo)用(yong)水(shui)(shui)(shui)17.57億立(li)方米(mi),發電(dian)(dian)(dian)用(yong)水(shui)(shui)(shui)14.68億立(li)方米(mi)。1991年(nian)(nian)(nian)(nian)又開工(gong)(gong)(gong)(gong)(gong)興建(jian)(jian)受益(yi)(yi)(yi)練江片5個鎮96個村的(de)秋(qiu)(qiu)風(feng)(feng)(feng)自來水(shui)(shui)(shui)廠。該項工(gong)(gong)(gong)(gong)(gong)程(cheng)完成后(hou),作為粵東地區(qu)大的(de)以水(shui)(shui)(shui)庫(ku)(ku)為水(shui)(shui)(shui)源工(gong)(gong)(gong)(gong)(gong)程(cheng)的(de)供水(shui)(shui)(shui)系(xi)統,將(jiang)南山(shan)清泉,通過輸水(shui)(shui)(shui)管(guan)道網送給練江平(ping)原千(qian)(qian)家(jia)(jia)萬(wan)(wan)戶(hu),改善50多(duo)萬(wan)(wan)人(ren)民(min)的(de)飲用(yong)水(shui)(shui)(shui)源。秋(qiu)(qiu)風(feng)(feng)(feng)水(shui)(shui)(shui)庫(ku)(ku)的(de)經濟效益(yi)(yi)(yi)、社會環境效益(yi)(yi)(yi)從此(ci)更加(jia)明顯(xian)。
由(you)于水(shui)庫(ku)建設受當(dang)時(shi)歷史條件限制,設計標準低,質量差,雖經多次加(jia)固、擴建與配(pei)套,主要建筑(zhu)物(wu)仍存在不同程度的險患(huan),2000年被測定為三類險壩(ba)。
為消(xiao)除水(shui)庫安全隱患,實現安全達標,2002年(nian)(nian)經(jing)省批準(zhun)立(li)項(xiang)同意計(ji)劃投入資金5266萬元,按50年(nian)(nian)一遇洪(hong)(hong)水(shui)標準(zhun)設計(ji),100年(nian)(nian)一遇洪(hong)(hong)水(shui)標準(zhun)校核進(jin)行除險加固。
