工业和采矿活动是土壤重金属污染的主要来源。基于压力-状态-响应模型，建立了工矿集聚区土壤环境综合评价方法。应用该方法对天津市典型工矿聚集区土壤环境质量进行了评价。结果如下：（1）研究区土壤综合环境质量指数为0.532，处于警戒状态，土壤环境总体较差。(2)压力指数、状态指数和响应指数分别为0.609、0.634和0.163，表明研究区土壤环境中的压力勉强可以接受，状态仅为尚可。此外，应对措施也不理想。(3)响应指数低表明研究区企业生产工艺差、污染物处理水平低、管理水平不高。(4)土壤风险的分布与污染源和土地利用类型密切相关。而且，分布也有一定的不均匀性。最后，对典型的石化、冶金等重污染企业工矿聚集区的优化、调整和管理提出了建议。
Industrial and mining activities have been recognized as major sources of heavy metal contamination in soil. Here, we developed a comprehensive assessment method for the soil environment in industrial and mining gathering areas based on the pressure–state–response model. Using this method, we assessed the environmental quality of soil in a typical industrial and mining gathering area in Tianjin City, China. The results are as follows: (1) The comprehensive environmental quality index of the soil in the study area was 0.532, which corresponds to an alert state and shows that the soil environment is generally poor. (2) The pressure, state, and response indexes were 0.609, 0.634, and 0.163, respectively, which suggests that the pressure in the soil environment of the study area is barely acceptable, and the state is merely passable. Furthermore, the response measures are not ideal. (3) The low response index scores indicate poor production processes, low pollutant treatment level, and unsatisfactory level of management by the enterprises in the study area. (4) The distribution of soil risks was found to be inseparably related to that of contamination sources and land use types. Furthermore, the distribution was uneven to a certain degree. Finally, we propose recommendations for the optimization, adjustment, and management of typical industrial and mining gathering areas with petrochemical, metallurgy, and other heavily polluting enterprises.
