摘　　要：基于经济学、生态学和资源管理学理论,建立生态—社会—经济价值耦合核算体系,结合北京市原东方化工厂蜕变为城市森林绿心公园的再生历程,探索采取近自然解决方案进行风险管控和生态恢复的碳中和潜力和城市棕地再生的多维协同增效效果。研究发现:生态恢复和功能提升是城市棕地再生的首要目标,近自然解决方案不仅能明显改善土壤环境、消除污染风险,还能持续增强固碳释氧、水文调节、生物多样性等生态系统服务功能,其中固碳能力以28%的最高占比贡献了每年903.88万元的生态价值,实现碳中和;社会价值是棕地景观重塑的核心功能,在文化弘扬、教育研学、旅游休憩和景观观赏中发挥重要作用,其在价值总量中的占比逐年递增,预测公园开园第4年将超过生态价值和经济价值,贡献率增至51.71%;城市棕地治理再生对周边房产具有显著的溢价增值作用,在北京市土地和房地产市场规律下,公园景观溢价率高达9.57%,棕地再生的经济价值创造力占公园开园首年价值核算总量的77.18%,虽然短期内占比较高,但长期预测将于开园第4年被社会价值反超。近自然解决方案是棕地重新融入城市机体,在碳中和目标导向下实现国土资源生态产品价值的有效路径,对于城市棕地再生设计和可持续发展具有重要的决策参考价值。Based on the theories of economics,ecology,and resource management,an ecological-social-economic value coupling accounting system was established.Combining with the regeneration process of the former Beijing Orient Chemical Plant into the Urban Central Green Forest Park,the carbon neutrality potential of adopting near-natural solutions for risk management and control and ecological restoration,as well as the multi-dimensional synergistic effect of urban brownfield regeneration,was explored.The research found that:(1)Ecological restoration and function enhancement are the primary goals of urban brownfield regeneration.Near-natural solutions could not only significantly improve the soil environment and eliminate pollution risks,but also continuously enhance the ecosystem service functions such as carbon sequestration and oxygen release,hydrological regulation,and biodiversity.Among them,the carbon sequestration capacity contributed an ecological value of 9.0388 million yuan per year with the highest proportion of 28%,achieving carbon neutrality.(2)Social value was the core function of brownfield landscape remodeling and played an important role in cultural promotion,educational research,tourism and leisure,and landscape appreciation.Its proportion in the total value increased year by year,and it was predicted that in the fourth year after the park opened,it would exceed the ecological value and economic value,and the contribution rate would increase to 51.71%.(3)The governance and regeneration of urban brownfields had a significant effect of premium and value increase on the surrounding properties.Under the laws of the land and real estate market in Beijing,the landscape premium rate of the park was as high as 9.57%,and the economic value creation ability of brownfield regeneration accounted for 77.18%of the total value accounting in the first year after the park opened.Although the proportion was relatively high in the short term,it was predicted that in the fourth year after the park opened,it would be surpassed
