記者從水(shui)利部獲悉：南水(shui)北調東中線(xian)一期(qi)工程累(lei)計調水(shui)200億(yi)立方米，供(gong)水(shui)量(liang)逐年增(zeng)加，已(yi)成為京津冀(ji)豫(yu)魯(lu)地(di)區受(shou)水(shui)區大中型城市的供(gong)水(shui)生(sheng)命線(xian)，直接受(shou)益人口(kou)超過1億(yi)人，工程正在穩步達效。

　　據悉，南水(shui)(shui)北(bei)(bei)調中(zhong)(zhong)線一期工程已不間斷(duan)安全(quan)供(gong)(gong)(gong)水(shui)(shui)1371天，共調水(shui)(shui)169.29億立方(fang)(fang)(fang)(fang)米(mi)，累計向(xiang)京津冀豫4省市供(gong)(gong)(gong)水(shui)(shui)超(chao)158億立方(fang)(fang)(fang)(fang)米(mi)，分別(bie)向(xiang)北(bei)(bei)京供(gong)(gong)(gong)水(shui)(shui)38.75億立方(fang)(fang)(fang)(fang)米(mi)、天津供(gong)(gong)(gong)水(shui)(shui)31.57億立方(fang)(fang)(fang)(fang)米(mi)、河南供(gong)(gong)(gong)水(shui)(shui)58.97億立方(fang)(fang)(fang)(fang)米(mi)、河北(bei)(bei)供(gong)(gong)(gong)水(shui)(shui)29.26億立方(fang)(fang)(fang)(fang)米(mi)。其(qi)中(zhong)(zhong)2017—2018年(nian)(nian)度(du)前(qian)10個月已實際供(gong)(gong)(gong)水(shui)(shui)57.57億立方(fang)(fang)(fang)(fang)米(mi)，提前(qian)超(chao)額完成年(nian)(nian)度(du)供(gong)(gong)(gong)水(shui)(shui)計劃。東線已累計調水(shui)(shui)到山(shan)東30.67億立方(fang)(fang)(fang)(fang)米(mi)。其(qi)中(zhong)(zhong)2017—2018年(nian)(nian)度(du)調水(shui)(shui)到山(shan)東10.88億立方(fang)(fang)(fang)(fang)米(mi)，比上一年(nian)(nian)度(du)增加(jia)22%。

　　從缺水(shui)(shui)(shui)(shui)(shui)(shui)(shui)到喝上(shang)好水(shui)(shui)(shui)(shui)(shui)(shui)(shui)，南(nan)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)北(bei)調中線(xian)輸水(shui)(shui)(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)質一(yi)直保(bao)持或優于Ⅱ類，不(bu)僅保(bao)障了(le)北(bei)方人民飲(yin)(yin)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)安(an)全，還從根本(ben)上(shang)改變了(le)北(bei)方受水(shui)(shui)(shui)(shui)(shui)(shui)(shui)區(qu)的供水(shui)(shui)(shui)(shui)(shui)(shui)(shui)格局，供水(shui)(shui)(shui)(shui)(shui)(shui)(shui)保(bao)證程度大幅(fu)提升，水(shui)(shui)(shui)(shui)(shui)(shui)(shui)質、飲(yin)(yin)用(yong)口感大為改善，已(yi)成(cheng)為京津冀豫(yu)魯地區(qu)不(bu)少城市供水(shui)(shui)(shui)(shui)(shui)(shui)(shui)的主力水(shui)(shui)(shui)(shui)(shui)(shui)(shui)源。

　　南水(shui)北調促進沿(yan)線綠色(se)發(fa)展。據測算，東(dong)中(zhong)線受水(shui)城(cheng)市每年(nian)增加工農(nong)業(ye)產值(zhi)近千億元。北京(jing)、天津、鄭州、石家莊(zhuang)、濟南等(deng)北方(fang)城(cheng)市水(shui)資源短(duan)缺(que)問(wen)題得到緩解(jie)，為經濟結構調整和產業(ye)轉型(xing)創造了機會和空間。同(tong)時，工程還助推了水(shui)源區的經濟發(fa)展和產業(ye)結構調整，如中(zhong)線水(shui)源區湖(hu)北十堰市近5年(nian)GDP增速(su)平(ping)(ping)均(jun)(jun)達到9%，超過全國平(ping)(ping)均(jun)(jun)水(shui)平(ping)(ping)。

　　南水(shui)(shui)北(bei)調東中(zhong)線(xian)(xian)工(gong)程(cheng)還(huan)顯著(zhu)(zhu)改善了(le)沿(yan)線(xian)(xian)水(shui)(shui)源條(tiao)件，遏制了(le)地(di)下水(shui)(shui)超采狀況，增加了(le)生(sheng)態環境用(yong)水(shui)(shui)，改善了(le)河(he)(he)流(liu)生(sheng)態。通過優化調度，中(zhong)線(xian)(xian)工(gong)程(cheng)連續(xu)兩年(nian)利用(yong)汛期棄水(shui)(shui)向受水(shui)(shui)區實施生(sheng)態補水(shui)(shui)，已累計補水(shui)(shui)11.6億立方米，生(sheng)態效(xiao)益顯著(zhu)(zhu)。3年(nian)來，北(bei)京、天(tian)津等6省(sheng)市累計壓(ya)減地(di)下水(shui)(shui)開(kai)采量逾8億立方米，地(di)下水(shui)(shui)位得(de)到(dao)不同程(cheng)度回(hui)升(sheng)。其(qi)中(zhong)，2016年(nian)和2017年(nian)底北(bei)京平(ping)原區地(di)下水(shui)(shui)位分別較同期回(hui)升(sheng)0.52米、0.23米。天(tian)津海河(he)(he)水(shui)(shui)生(sheng)態得(de)到(dao)明顯改善，地(di)下水(shui)(shui)位保持穩定(ding)或(huo)小幅回(hui)升(sheng)。（記(ji)者趙永平(ping)）
