| 中文摘要 |
| 定量评估水源涵养与人类活动的耦合协调及空间关联关系,对缓解黄河流域人水矛盾与推动社会-生态系统协调发展具有重要意义. 运用InVEST模型和人类活动强度（HAI）,对黄河流域水源涵养与人类活动进行了定量评估,结合耦合协调度和双变量空间自相关,分析了黄河流域县域水源涵养与人类活动的时空耦合及空间关联关系. 结果表明：①1980~2020年黄河流域水源涵养量呈波动上升趋势,多年平均水源涵养量为58.231 4亿m3,表现为上下游区域较高,中游较低的空间分布格局. ②1980~2020年黄河流域人类活动强度呈逐步上升趋势,HAI值由1980年的0.143 4上升到2020年的0.185 5,县域尺度下人类活动强度整体上呈东高西低的空间分布格局. ③1980~2020年黄河流域县域水源涵养与人类活动耦合协调水平上升但仍处于失调状态,呈现“中度失调为主体,极度、严重失调减少,轻度、濒临失调增加”的动态演化特征和东高西低的空间分布格局. ④1980~2020年黄河流域县域水源涵养与人类活动之间呈现空间负相关关系,且负向效应加剧,最主要的关系类型和县域数量减少最多的均为低-低聚类. |

| Quantitative evaluation of the coupling coordination and spatial correlation between water conservation and human activities is crucial for alleviating the contradiction between human beings and water and promoting the coordinated development of social-ecological systems in the Yellow River Basin. The InVEST model and human activity intensity （HAI） were used to quantitatively evaluate water conservation and human activities in the Yellow River Basin. The spatiotemporal coupling and spatial correlation between water conservation and human activities in the counties of the Yellow River Basin were analyzed by combining the coupling coordination degree and bivariate spatial autocorrelation. The results showed that： ① From 1980 to 2020, the water conservation in the Yellow River Basin showed a fluctuating upward trend, with an average annual water conservation of 5.823 14 billion m3, showing a spatial distribution pattern of higher water conservation in the upstream and downstream areas and lower water conservation in the middle reaches. ②From 1980 to 2020, the intensity of human activities in the Yellow River Basin showed a gradual upward trend, with the HAI value increasing from 0.143 4 in 1980 to 0.185 5 in 2020. The overall spatial distribution pattern of human activity intensity at the county level was high in the east and low in the west. ③From 1980 to 2020, the coupling coordination level between water conservation and human activities in the Yellow River Basin counties increased but remained in a state of imbalance, showing a dynamic evolutionary characteristic of “moderate imbalance as the main body, with extreme and severe imbalance decreasing and mild and critical imbalance increasing” and a spatial distribution pattern of high in the east and low in the west. ④ From 1980 to 2020, there was a spatial negative correlation between water conservation and human activities in the Yellow River Basin counties, and the negative effect intensified. The most important relationship type and the county with the largest decrease in number were low-low clusters. |
