【正文】 類 ≤5 mg/L廠界噪聲執(zhí)行《工業(yè)企業(yè)廠界噪聲標準》(GBl2348—90)II 類；施工期噪聲執(zhí)行《建筑施工場界噪聲限值》(GB12523— 90)。評價范圍為規(guī)劃的各級電站庫區(qū)范圍及可能引起的減脫13 / 73水河段。大墓結構風格獨特，為我國考古發(fā)覺中絕無僅有。規(guī)劃的主要內容包括：根據(jù)XX 水文站的水文資料，全面準確地評價 XX 河流域的水資源條件和特點，系統(tǒng)評價流域水資源的數(shù)量、質量、能量、可利用量等，根據(jù)社會經濟發(fā)展預測、節(jié)水、水資源保護利用規(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，以鄉(xiāng)鎮(zhèn)為中心的防洪減災保障體系，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區(qū)的防洪安全，最大限度地減輕洪澇災害，非工程措施主要是結合水土保持工程來規(guī)避洪災風險；提出流域水電開發(fā)利用規(guī)劃，建議建設 3 個水電站，合理開發(fā)水能以替代煤和生物能，既減輕農民負擔，又減少對環(huán)境的破壞；最后提出水資源保護和水土保持規(guī)劃。I / 73目 錄目 錄
