【正文】 需要適時(shí)、靈活擴(kuò)大市場范圍；4) 尊重市場經(jīng)濟(jì)規(guī)律，結(jié)合目標(biāo)市場實(shí)際用能情況，合理預(yù)測天然氣市場規(guī)模；5)堅(jiān) 持科學(xué)態(tài)度，積極采用新工藝、新技術(shù)、新設(shè)備和新材料，確保供氣系統(tǒng)的安全性、穩(wěn)定性和可靠性，同時(shí)考慮經(jīng)濟(jì)合理，盡量節(jié)約用地和投資；6) 嚴(yán)格遵守國家、行業(yè)、部門的有關(guān)政策及法令、法規(guī)，遵守相關(guān)規(guī)范、標(biāo) 準(zhǔn)和技術(shù)規(guī)定。目前原煤、電力仍是某某縣能源消耗的主要品種，占總量的 80%，隨著近年來產(chǎn)業(yè)和資本的大規(guī)模進(jìn)入，當(dāng)?shù)氐沫h(huán)保、清潔能源供應(yīng)以及能源結(jié)構(gòu)優(yōu)化等問題愈發(fā)嚴(yán)峻。輸氣管道工程可研.輸氣管道工程可行性研究報(bào)告輸氣管道工程可研.目 錄1 總 論
