摘要: 目的 为 探 究 治 沟 造 地 和 平 山 造 城 重 大 工 程 对 延 河 流 域 生 态 地 质 环 境 承 载 力（ecogeological environment carrying capacity，EGCC）的影响， 方法 利用分形理论和信息量模型构建研究区 EGCC 评价模型，揭示延河流域环境承载力时空模式及流转态势，构建人类活动强度指数，采用最小二乘法和皮尔逊相关系数探讨人类活动与 EGCC 之间的关系。 结果 结果表明：延河流域 1990—2018 年 EGCC 整体状况明显改善，平均值从−0.299 上升至−0.197；EGCC 分布多年来呈“中部最高，东南次之，西北最低”格局；人类活动强度从 1990 年成片分布逐渐发展到2018 年“单核辐射”分布，高强度区主要分布在延河流域中部；人类活动强度与 EGCC 相关度较高，一定范围内呈正向促进关系；受平山造城工程活动影响，2010—2018 年高水平和较高水平承载力面积分别增加了 1.610，3.164 km²；EGCC 变化趋势因治沟造地工程所处乡、镇地理位置和发展侧重不同而存在差异。 结论 人类活动与生态地质环境承载力表现出较强的正相关关系，治沟造地和平山造城工程对 EGCC 具有一定积极影响。

Abstract: Objectives To investigate the influence of the gully land consolidation project and large-scalel and infilling and excavation project on the eco-geological environment carrying capacity（EGCC） of the in the Yanhe River Basin. Methods Fractal theory and information quantity model were used to construct an EGCC evaluation model for the study area，revealing the spatial and temporal patterns and flow dynamics of EGCC.The human activity intensity index was constructed，and the least squares method and Pearson correlation coefficient were used to explore the relationship between human activities and EGCC. Results From 1990 to 2018，the EGCC of the Yanhe River has improved significantly.The average value increased from −0.299 to −0.197，The distribution over the years showed a pattern of “the highest in the middle，the second highest in the southeast and the lowest in the northwest”.The distribution pattern of human activity intensity from 1990 to 2018 change from patchy distribution to “single-core radiation” distribution，with the high intensity area mainly distributed in the central part.Furthermore，the correlation between human activity intensity and EGCC is high and has a positive contribution in a certain range.From 2010 to 2018，under the influence of large-scale land infilling and excavation project，the area of high-level and higher-level EGCC increased by 1.610 km² and 3.164 km²，respectively.The trend of the gully management project and EGCC varies according to the geographical location and development focus of townships. Conclusions Overall，human activities show a strong positive correlation with the EGCC，and the gully land consolidation project and large-scale land infilling and excavation project have a positive impact on the EGCC.
