| 摘要: |
| 【目的】探究1990—2020年黄河流域河南段生境质量时空变化格局，为流域生态恢复和可持续发展提供科学依据。【方法】运用InVEST模型生境质量模块、GIS空间自相关和地理探测器模型分析黄河流域河南段生境质量时空变化特征并识别其驱动因子。【结果】黄河流域河南段土地利用变化表现为耕地、草地面积显著减少，建设用地面积增加1倍。黄河流域河南段生境质量平均值处于中等水平，生境质量呈西高东低的空间分布格局。1990—2020年，生境质量存在强聚集效应，年际聚集性波动下降；土地利用是该区域生境质量变化的主要驱动因子，土地利用与高程、气温、NDVI、坡度、降水量、GDP和人口密度的交互协同作用值均大于0.95。【结论】1990—2020年，黄河流域河南段区大部分区域的生境质量处于较低水平，建设用地不断扩张，城市群问题突出，提升黄河流域河南段的生境质量并制定科学的土地规划势在必行。 |

| Abstract: |
| 【Objective】The ecological functions of the Yellow River Basin have undergone significant changes in recent decades due to both natural and anthropogenic influences. In this paper, we analyze the spatiotemporal variation in habitat quality within the Henan Section of the basin from 1990 to 2020 to help ecological restoration and sustainable development in the region. 【Method】Habitat quality was assessed using the habitat quality module in the InVEST model and spatial autocorrelation analysis in GIS. Key determinants of spatiotemporal variation were identified using the Geodetector method.【Result】Over the past 30 years, the study area experienced a marked reduction in cultivated land and grassland, alongside a more than twice increase in construction land. The average habitat quality in the Henan Section was moderate, generally higher in the west and lower in the east. From 1990 to 2020, habitat quality exhibited strong spatial clustering, despite year-to-year fluctuations. Land use type was the primary driver of habitat quality change. Interaction effects between land use and variables such as elevation, temperature, NDVI, slope, precipitation, GDP, and population density all had explanatory power exceeding 0.95.【Conclusion】 Habitat quality in most parts of the Henan Section of the Yellow River Basin remained low from 1990 to 2020, with the decline closely linked to the expansion of construction land, particularly in urban areas. Science-based land use planning is essential to improving habitat quality and ensuring ecological sustainability of the region. |
