庫區移民
庫區進行了兩次(ci)大(da)規模移(yi)民,先后搬遷(qian)建村(cun)43個(ge),移(yi)民6952戶27803人,拆除(chu)房(fang)屋26891間,淹占(zhan)土地4326.7公頃(qing)。
水庫效益
青峰(feng)嶺水庫經過(guo)歷年配套、加固維修、工程逐步完善(shan)、效益(yi)顯著。水庫建成后(hou),對已(yi)發生的(de)洪水消(xiao)減洪峰(feng)達40%。灌區自(zi)開灌到1999年,累計灌溉面積27.09萬公頃,累計發電7186.14萬千(qian)瓦時,累計養(yang)殖各種魚(yu)類297.7萬千(qian)克。青峰(feng)嶺灌溉山東省莒(ju)縣、沂南縣10個鄉(xiang)鎮(zhen)、284個自(zi)然村的(de)土(tu)地(di)。灌區以(yi)小麥、水稻、玉米等作物為(wei)主,是全縣的(de)主要商(shang)品糧生產基地(di)。
水庫下(xia)游保(bao)護著莒縣、臨沂、郯(tan)城等縣城的工礦企業,82萬(wan)畝農田和(he)100多萬(wan)人口,水庫下(xia)游25千米處有濰(wei)徐公路(lu)(lu),115千米處有兗石鐵路(lu)(lu),180千米處有隴海鐵路(lu)(lu)。自1960年建庫以來,水庫有效地攔蓄了(le)上游來水,保(bao)障了(le)沭河(he)下(xia)游沿河(he)兩(liang)岸人民生(sheng)命和(he)財產的安全。
信息化建設
青峰嶺水(shui)庫管理處積極推進(jin)管理現代(dai)化(hua),辦公自(zi)動(dong)化(hua)建設(she),先后建成視頻監控系(xi)統和大壩(ba)(ba)測(ce)(ce)壓管自(zi)動(dong)化(hua)觀測(ce)(ce)系(xi)統、電(dian)站(zhan)自(zi)動(dong)化(hua)運行(xing)監測(ce)(ce)系(xi)統、溢洪(hong)閘遠程啟閉(bi)監測(ce)(ce)系(xi)統、灌(guan)區節水(shui)自(zi)動(dong)化(hua)測(ce)(ce)水(shui)量水(shui)與水(shui)費查詢系(xi)統,并(bing)配有檔案管理軟件2套。同(tong)時,通過在(zai)灌(guan)區各(ge)引水(shui)渠(qu)首,重要閘門設(she)置(zhi)自(zi)動(dong)監測(ce)(ce)點,對管理處各(ge)處的監控進(jin)行(xing)統一整合,大壩(ba)(ba)測(ce)(ce)壓管、溢洪(hong)閘啟閉(bi)、電(dian)站(zhan)中控室、灌(guan)區主要渠(qu)首等重要監測(ce)(ce)點的實時數據都能(neng)實現遠程了解(jie),真(zhen)正做到了早發(fa)現早預防。
未來規劃
水(shui)庫(ku)將變身旅游區
莒縣(xian)(xian)旅游局正(zheng)在(zai)規劃在(zai)青峰(feng)嶺(ling)水庫(ku)建設青峰(feng)湖(hu)旅游區(qu),初步計劃旅游區(qu)范圍,東(dong)至(zhi)水庫(ku)大壩以東(dong)的(de)(de)茅(mao)埠村(cun),北到(dao)(dao)天(tian)寶村(cun),南到(dao)(dao)西地村(cun),西到(dao)(dao)東(dong)楊家村(cun),具體范圍是連(lian)接茅(mao)埠-龐(pang)莊(zhuang)-三(san)莊(zhuang)-石(shi)泉官莊(zhuang)-車(che)峰(feng)峪-碁山鄉-河東(dong)-天(tian)寶村(cun)-北陳莊(zhuang)-謝家莊(zhuang)-黑石(shi)溝(gou)-油(you)坊-安莊(zhuang)鎮(zhen)-劉家南湖(hu)-豐(feng)家泥溝(gou)-西地-南青峰(feng)嶺(ling)-茅(mao)埠的(de)(de)縣(xian)(xian)道或鄉道圍合而成的(de)(de)區(qu)域,總面(mian)積約(yue)120平方千(qian)米。
安(an)莊鎮瞅準這個(ge)旅游區規劃(hua),已經規劃(hua)出千畝(mu)果品(pin)示范基地,果樹成(cheng)熟后可(ke)以讓游客(ke)采(cai)摘。目前已經在(zai)(zai)前丁果莊村(cun)流(liu)轉土(tu)地1133畝(mu),建設千畝(mu)果品(pin)示范基地,已栽植蘋果 400畝(mu),核桃400畝(mu),梨150畝(mu)。村(cun)里(li)的(de)農民(min)通過土(tu)地流(liu)轉得到的(de)補償金比自己種(zhong)地收入(ru)所(suo)得還多,現(xian)在(zai)(zai)青壯年外出打(da)工,一(yi)天能收入(ru)上百元(yuan)。年紀大(da)的(de)就在(zai)(zai)村(cun)里(li)打(da)工,幫忙管(guan)理果園,一(yi)個(ge)月也能收入(ru)近兩千元(yuan)。這個(ge)模(mo)式將成(cheng)為庫(ku)區移民(min)產(chan)業(ye)轉型的(de)范本。
