【摘要】 工业园区通过对生产资源的集成为产业发展提供了优势和便利,但同时也造成了较高的土壤、地下水潜在污染风险。选取位于长江上游成都平原的原青白江工业集中发展区作为研究对象,检验分析了园区土壤超标地块和未超标地块,以及地下水超标和未超标地块之间在11个变量上的差异性,发现地面硬化水平对地块土壤污染风险存在显著影响,地下构筑物防渗情况对地块地下水污染风险影响在显著影响,而企业生产经营活动时长对地块的土壤、地下水污染风险的影响均显著。据此,本研究对同类型工业园区提出了土壤与地下水污染风险防控建议:1)对成立时间早、生产历史长的地块执行更严格的管理措施; 2)对企业地面硬化情况和地下构筑物防渗水平提出更高要求; 3)在制定园区重点控制的有毒有害化学物质清单时,充分考虑生产原料中的伴生污染物; 4)开展园区环境监测时,充分考虑不同企业地块间的污染交互影响。更多还原

【Abstract】 Industrial parks confer advantage and convenience for industrial development by integrating production resources,but also increase the potential risk of soil and groundwater pollution. The Qingbaijiang Industrial Park located in Chengdu plain of upper Yangtze River has been chosen as research object,to test the difference of 11 variables between soil-pollution exceeding and non-exceeding crucial enterprise yards,and groundwater-pollution exceeding and non-exceeding yards. It turns out that the ground hardening affects the risk of soil-pollution significantly,the leakage proof measures of underground facilities affects the risk of groundwater-pollution significantly,and the influence of industrial duration time on the risk of both soil and groundwater pollution is significant. Accordingly,for similar industrial parks,we suggest to adopt stricter environmental management approach for the yards with long industrial duration time,and to raise the standard of ground hardening and the leakage proof measures of underground facilities. Besides,pay more attention on associated pollutants of producing materials when listing the key-managed toxic chemical substances of industrial park,and give full consideration to the polluting interfere of different crucial enterprise yards when monitoring the soil and groundwater environment of the industrial park.更多还原
