摘要: 生物多样性的变化及其驱动机制对制定生物多样性保护措施意义重大。遥感技术在大尺度、长时序研究中优势突出,为了掌握黄河流域动物多样性的空间格局及时序变化,本文利用2000—2022年的时序Landsat、MODIS卫星影像数据,结合GEE、InVEST模型、GIS相关技术,基于物种多样性、生态系统多样性的7个指标构建黄河流域动物多样性评估指数,基于实测数据开展精度评估,并进行驱动因素分析。结果表明,本文构建的动物多样性评估指数(BI)精度较高,与实测物种数据的相关性为0.80;22年间黄河流域BI整体呈上升趋势;BI提高区域的面积占总面积的70.63%,降低区域占29.37%;基于驱动因子贡献度分析,蒸发量为影响黄河流域动物多样性的首要环境控制因子。

Abstract: Changes in biodiversity and their driving mechanisms are of great significance to the development of biodiversity conservation measures.Remote sensing technology has outstanding advantages in large-scale and long time-series research.In order to grasp the spatial pattern and time-series changes of animal diversity in the Yellow River basin,this study utilizes the time-series Landsat and MODIS satellite image data from 2000 to 2022,and combines the GEE,InVEST model,and GIS-related technologies to construct an index for assessing the animal diversity in the Yellow River basin based on 7 indicators in 2 aspects:species diversity and ecosystem diversity.The animal diversity assessment index of the Yellow River basin is constructed based on seven indicators of species diversity and ecosystem diversity,and the accuracy assessment is carried out based on the measured data,and the analysis of the driving factors is also carried out.The results show that:the BI constructed in this study had high precision,and the correlation with the measured species data is 0.80; the BI in the Yellow River basin shows an overall increasing trend during the 22 year perios; the area of the BI increases accounted for 70.63%of the total area,and the area of the BI decreases accounted for 29.37%; based on the analysis of the contribution of the driving factors,evapotranspiration is the primary environmental control factor.
