摘要：以江蘇沿海40家化工園區(qū)為例,綜合考慮化工園區(qū)評(píng)價(jià)單元與環(huán)境風(fēng)險(xiǎn)區(qū)域性、系統(tǒng)性和行業(yè)性特征,構(gòu)建了包括風(fēng)險(xiǎn)源、控制機(jī)制、風(fēng)險(xiǎn)受體3項(xiàng)一級(jí)指標(biāo)、9項(xiàng)二級(jí)指標(biāo)的環(huán)境風(fēng)險(xiǎn)分級(jí)綜合模型,提出以指標(biāo)貢獻(xiàn)率作為優(yōu)先管理策略的半定量篩選依據(jù).結(jié)果表明,研究區(qū)域內(nèi)共有江蘇響水陳家港化工集中區(qū)、江蘇連云港化工產(chǎn)業(yè)園區(qū)、如皋精細(xì)化學(xué)工業(yè)園等7個(gè)高風(fēng)險(xiǎn)園區(qū),其風(fēng)險(xiǎn)產(chǎn)生與園區(qū)產(chǎn)業(yè)結(jié)構(gòu)、園區(qū)地理布局緊密相關(guān).根據(jù)指標(biāo)貢獻(xiàn)度將7個(gè)高風(fēng)險(xiǎn)化工園區(qū)劃分為兩類化工園區(qū):一類是以受體敏感性為主控風(fēng)險(xiǎn)因素的化工園區(qū);一類以風(fēng)險(xiǎn)源以及風(fēng)險(xiǎn)控制為主控因素的化工園區(qū).針對(duì)這兩類化工園區(qū),分別從環(huán)境監(jiān)管、提高清潔生產(chǎn)水平、化工企業(yè)數(shù)量總量控制、污水處理廠及配套管網(wǎng)建設(shè)等方面提出優(yōu)先管理策略.

Abstract：Acomprehensive environment risk ranking model was established including 3 first-grade indicators (including risk source indicator, risk controlling indicator and risk receptor indicator) and 9 second-grade indicators. The characteristics of region, system and industry for environmental risks as well as features of industrial parks were simultaneously considered, and a semi-quantitative screening approach based on indicators’ contribution was applied to prior management strategy in a case study of 40 industrial parks in the coast area of Jiangsu Province. 7 chemical industrial parks (including Chenjiagang Chemical Industry Park of Xiangshui, Chemical Industry Park of Lianyungang, Rugao Fine Chemical Industry Park, etc.) were ranked higher in environmental risk assessment, which were closely related to their industrial structures and geographical distributions. The 7 high risk industrial parks were categorized into two groups by the characteristics of indicators’ contributions. One group was risk receptor dominated, and the other was risk sources and risk control dominated chemical industrial parks. Finally, different priority management strategies were proposed to these two groups.
