Resources and Environmental Carrying Capacity (RECC) is a comprehensive concept that encompasses the interactions between resources, the environment, and human activities, serving as the foundation for social development strategies. To adequately reflect this complex relationship, a multi-level, multi-dimensional evaluation indicator system must be developed. This paper constructs a regional soil environmental evaluation system incorporating PM2.5 indicators, which is in line with relevant environmental protection policies and planning orientations in our country from 2014 to 2023. It analyzes the level and development trend of RECC in Henan Province and proposes measures for effective management. The results indicate the following: (1) The RECC in Henan Province demonstrates a downward trajectory, marked by temporary fluctuations over time. It hit its nadir in 2019, subsequently undergoing a gradual resurgence; (2) Analysis of individual dimension indicators reveals that the natural carrying capacity has declined from a medium to a relatively weaker level. Meanwhile, environmental carrying capacity has shown a slight downward trend but has generally remained stable. In contrast, socio-economic carrying capacity has demonstrated an upward trend, rising from a medium to a relatively strong level. In terms of early warning measures, it is essential to establish a red warning zone, implement a credit record accountability system, and develop a monitoring warning database along with an information technology platform. This paper demonstrates that the indicator system is effective for evaluating RECC across different dimensions and holds significant reference value for assessing RECC in similar regions.资源环境承载力（Resources and Environmental Carrying Capacity，RECC）是涵盖资源、环境与人类活动间相互作用的复合概念，亦是社会发展战略制定的核心依据。为充分体现这一复杂关联，需构建多维度、多层级的评价指标体系。本文构建了纳入PM2.5指标的区域土壤环境评价体系，该体系契合我国2014至2023年相关环境保护政策与规划导向。本文分析了河南省资源环境承载力水平与发展趋势，并提出了高效管控的优化举措。研究结果显示：（1）河南省资源环境承载力整体呈下降态势，期间伴随阶段性波动，并于2019年跌至谷底，随后逐步回升；（2）分维度指标分析结果显示：自然承载力已从中等水平降至相对较弱水平；环境承载力虽呈小幅下降趋势，但整体保持稳定；相较之下，社会经济承载力呈上升态势，从中等水平跃升至相对较强水平。针对预警防控工作，需设立红色预警管控区，建立信用记录问责机制，并搭建监测预警数据库与信息化技术平台。本研究表明，该指标体系可有效实现多维度资源环境承载力评价，对同类区域的资源环境承载力评估具有重要参考价值。
