污染场地风险管控可持续评价指标体系构建及关键影响因素分析

以可持续发展理论和风险管理理念为基本原则的污染场地可持续风险管控已成为当前国际社会场地管理的重要决策问题和研究前沿热点，为明确影响污染场地风险管控可持续发展能力的决定性因素，基于国内外污染场地可持续风险管控相关文献的系统调研，构建契合我国场地管理背景的区域污染场地风险管控可持续评价体系，通过指标综合权重计算判定影响风险管控可持续发展能力的关键因子.结果表明，区域尺度上可能影响我国污染场地风险管控可持续性的指标多达44个，涵盖环境、社会、经济和技术这4个维度，单指标影响程度为0.26%～5.01%(平均值2.27%).潜在风险和温室气体排放(环境指标)、健康与安全和公众参与(社会指标)、管控成本和环保投资(经济指标)、修复周期和修复效果(技术指标)是影响我国污染场地风险管控可持续发展的重要因子，影响程度为1.89%～5.01%(平均值3.58%).具有较强政策敏感性的指标，包括考核指标、投融资创新、名录管理、能力建设、安全利用和制度建设等，对风险管控可持续性已经产生1.18%～3.48%的正向影响，随着政策制度的深入落实与全面地域推广，其对风险管控可持续发展的助力效应将更加明显.

Construction of Sustainability Evaluation Index System for Contaminated Site Risk Management and Analysis on Key Influential Factors

Based on the tenets of sustainability development and risk management, sustainable risk management and control for contaminated sites has gradually become one of the most important decision issues and research frontier topics in global land management. To identify the determining factors that might affect the sustainability of contaminated site risk management and control, a systematic analysis of relevant literature focusing on sustainable risk management and control for contaminated sites was conducted. Then, a sustainability evaluation index system was first established at a regional perspective, which further considered site management practices in China. Second, weight coefficients of all indicators were calculated to identify key factors that could largely affect the sustainability of risk management and control. The results showed that 44 indicators covering environment, society, economy, and technology aspects could potentially influence the sustainability of contaminated site risk management and control ranging between 0.26% and 5.01% (average 2.27%). In total, eight indicators were shown to be the most influencing factors in the sustainability of risk management and control, namely potential risks and GHG emissions in the environmental dimension, health and safety and public engagement in the social dimension, management cost and environmental investment in the economic dimension, and remediation time and effect in the technical dimension. Their contributions to sustainability ranged from 1.89%-5.01% (average 3.58%). Indicators with strong policy sensitivity, including performance assessment, investment and financing innovation, directory management, capacity-building, safe utilization, and system construction, tended to produce positive effects on the sustainability of risk management and control by approximately 1.18%-3.48%. However, the contributing effects are expected to be further improved with the in-depth implementation and regional promotion of policies.
