【正文】 類 ≤5 mg/L廠界噪聲執(zhí)行《工業(yè)企業(yè)廠界噪聲標(biāo)準(zhǔn)》(GBl2348—90)II 類；施工期噪聲執(zhí)行《建筑施工場(chǎng)界噪聲限值》(GB12523— 90)。評(píng)價(jià)范圍為規(guī)劃的各級(jí)電站庫(kù)區(qū)范圍及可能引起的減脫13 / 73水河段。大墓結(jié)構(gòu)風(fēng)格獨(dú)特，為我國(guó)考古發(fā)覺中絕無僅有。規(guī)劃的主要內(nèi)容包括：根據(jù)XX 水文站的水文資料，全面準(zhǔn)確地評(píng)價(jià) XX 河流域的水資源條件和特點(diǎn)，系統(tǒng)評(píng)價(jià)流域水資源的數(shù)量、質(zhì)量、能量、可利用量等，根據(jù)社會(huì)經(jīng)濟(jì)發(fā)展預(yù)測(cè)、節(jié)水、水資源保護(hù)利用規(guī)劃，做流域水資源供需平衡分析，確保水資源供需動(dòng)態(tài)平衡；提出流域防洪規(guī)劃，建立包括各種工程措施和非工程措施在內(nèi)，以鄉(xiāng)鎮(zhèn)為中心的防洪減災(zāi)保障體系，依靠防洪工程確保中心鄉(xiāng)鎮(zhèn)、人口聚集地和主要糧食生產(chǎn)區(qū)的防洪安全，最大限度地減輕洪澇災(zāi)害，非工程措施主要是結(jié)合水土保持工程來規(guī)避洪災(zāi)風(fēng)險(xiǎn)；提出流域水電開發(fā)利用規(guī)劃，建議建設(shè) 3 個(gè)水電站，合理開發(fā)水能以替代煤和生物能，既減輕農(nóng)民負(fù)擔(dān)，又減少對(duì)環(huán)境的破壞；最后提出水資源保護(hù)和水土保持規(guī)劃。I / 73目 錄目 錄
