【谷騰環保網訊】安徽省宿(su)州市日前(qian)完成全市主要河湖水生態環境調查評估工作。

據(ju)了解，宿州(zhou)市河(he)湖水(shui)(shui)系(xi)眾多，與鄰近的河(he)南省、江(jiang)蘇省有(you)多條重(zhong)要水(shui)(shui)系(xi)連通。在流域整體水(shui)(shui)質持續(xu)提升的背(bei)景下，維(wei)護(hu)并不斷優化宿州(zhou)市主要河(he)湖水(shui)(shui)生(sheng)(sheng)態系(xi)統健康狀(zhuang)況，對打造水(shui)(shui)清(qing)地綠(lv)天藍的淮河(he)生(sheng)(sheng)態經濟帶(dai)，加(jia)快建設底色更(geng)綠(lv)的現代化新宿州(zhou)具(ju)有(you)重(zhong)要意義。

2022年(nian)，為全(quan)面(mian)提升全(quan)市水(shui)(shui)生(sheng)態(tai)環境現代化管理水(shui)(shui)平，摸清(qing)全(quan)市主(zhu)要河湖濕地水(shui)(shui)生(sheng)態(tai)環境本底(di)狀況，宿(su)州市在省內率先啟(qi)動市級層面(mian)流域水(shui)(shui)生(sheng)態(tai)調查，針(zhen)對新(xin)汴河、澮河、沱(tuo)河等12條主(zhu)要河湖水(shui)(shui)體開展枯水(shui)(shui)期(qi)(qi)、平水(shui)(shui)期(qi)(qi)和豐水(shui)(shui)期(qi)(qi)水(shui)(shui)生(sheng)態(tai)環境調查。

調查覆(fu)蓋(gai)全市13個(ge)國家地表水(shui)(shui)考核斷面匯水(shui)(shui)單元，共(gong)布設62個(ge)調查監測點位，涵(han)蓋(gai)水(shui)(shui)質(zhi)、底泥(ni)、生(sheng)(sheng)(sheng)境(jing)、水(shui)(shui)生(sheng)(sheng)(sheng)生(sheng)(sheng)(sheng)物(wu)四(si)大部分共(gong)93項指標，3期(qi)調查共(gong)獲取生(sheng)(sheng)(sheng)境(jing)、水(shui)(shui)質(zhi)監測、底泥(ni)監測、水(shui)(shui)生(sheng)(sheng)(sheng)生(sheng)(sheng)(sheng)物(wu)數據(ju)1.4萬余條，完成水(shui)(shui)生(sheng)(sheng)(sheng)態(tai)健(jian)康(kang)綜合評估，形成3個(ge)水(shui)(shui)期(qi)水(shui)(shui)生(sheng)(sheng)(sheng)態(tai)健(jian)康(kang)檔(dang)案卡，建立水(shui)(shui)生(sheng)(sheng)(sheng)態(tai)環境(jing)數據(ju)庫，編制(zhi)宿州市常見水(shui)(shui)生(sheng)(sheng)(sheng)生(sheng)(sheng)(sheng)物(wu)圖譜(pu)。

調查與評(ping)估結果顯示，宿州市各水(shui)(shui)(shui)體(ti)水(shui)(shui)(shui)生(sheng)(sheng)生(sheng)(sheng)境質(zhi)量整(zheng)體(ti)良好，河(he)道自然岸線比例較高，水(shui)(shui)(shui)環境質(zhi)量整(zheng)體(ti)較好，水(shui)(shui)(shui)質(zhi)達(da)(da)標率高。2023年，宿州市國控斷面地表水(shui)(shui)(shui)優良率（達(da)(da)到或優于Ⅲ類）達(da)(da)到有監測記錄以來最好水(shui)(shui)(shui)平(ping)；11條河(he)流水(shui)(shui)(shui)生(sheng)(sheng)態健(jian)康狀況均處(chu)于良好水(shui)(shui)(shui)平(ping)，石龍(long)湖(hu)水(shui)(shui)(shui)生(sheng)(sheng)態健(jian)康狀況處(chu)于中等水(shui)(shui)(shui)平(ping)，平(ping)水(shui)(shui)(shui)期(qi)、豐水(shui)(shui)(shui)期(qi)水(shui)(shui)(shui)生(sheng)(sheng)態健(jian)康狀況相對(dui)枯水(shui)(shui)(shui)期(qi)更好。本(ben)次共調查出魚(yu)類20種(zhong)，大型底棲動物(wu)33種(zhong)，浮游植(zhi)物(wu)208種(zhong)，著生(sheng)(sheng)藻類181種(zhong)，水(shui)(shui)(shui)生(sheng)(sheng)植(zhi)物(wu)42種(zhong)。

根據調查(cha)評估(gu)結(jie)果，宿(su)州(zhou)市(shi)結(jie)合(he)不同(tong)時期水(shui)(shui)生(sheng)(sheng)態(tai)環境(jing)質量(liang)變化(hua)趨(qu)勢，甄別流域單(dan)元內突出的水(shui)(shui)生(sheng)(sheng)態(tai)環境(jing)問題。針(zhen)對河湖(hu)岸(an)坡種(zhong)植、底(di)泥內源(yuan)性污(wu)染較(jiao)為(wei)突出、部分(fen)水(shui)(shui)生(sheng)(sheng)生(sheng)(sheng)物多樣性偏低、部分(fen)河段外來入侵(qin)水(shui)(shui)生(sheng)(sheng)植物較(jiao)為(wei)嚴重等問題，宿(su)州(zhou)市(shi)將以工程化(hua)、項目化(hua)手段，從河湖(hu)沿岸(an)農業面源(yuan)污(wu)染控制、區域再生(sheng)(sheng)水(shui)(shui)循(xun)環利用、底(di)泥內源(yuan)污(wu)染控制與治(zhi)理(li)、提升生(sheng)(sheng)物多樣性、持續加(jia)強水(shui)(shui)生(sheng)(sheng)態(tai)監測等方面入手，綜合(he)開(kai)展重點河湖(hu)水(shui)(shui)生(sheng)(sheng)態(tai)環境(jing)保(bao)(bao)護與修復工作(zuo)，編制“一河一策”，推進系統(tong)治(zhi)理(li)，力爭實現“河湖(hu)有(you)(you)水(shui)(shui)”“有(you)(you)魚有(you)(you)草”“人水(shui)(shui)和諧”的美好愿景，為(wei)美麗宿(su)州(zhou)建(jian)設提供生(sheng)(sheng)態(tai)環境(jing)保(bao)(bao)護和高質量(liang)發展的有(you)(you)力支撐。
