    大熊猫国家公园(四川片区)景观生态风险分析及预测

    Landscape ecological risk analysis and prediction in the Sichuan section of Giant Panda National Park

    • 摘要: 以大熊猫国家公园(四川片区)所涉及的20个县(市、区)级行政区为研究区,选取2000、2008、2016和2023年的土地利用覆盖数据,分析23年间土地利用变迁过程并计算区域景观生态风险指数,探究研究区景观生态风险指数的时空分异和空间自相关性,加上PLUS模型预测的研究区2030年三种情景下土地利用变化,以此反映景观生态风险的空间布局.结果表明:(1)研究区2000-2023年土地利用类型中林地面积最大且呈增长趋势,其次是草地和耕地;(2)2000-2023年,研究区整体景观风险指数较低,空间上低、较低生态风险区分布较广;(3)2000-2023年研究区全局Moran’s I显著为正,局部空间集聚特征以高-高集聚和低-低集聚为主;(4)2030年经济优先、生态保护和自然发展三种情景下景观生态风险的空间分布遵循历史分布规律,生态保护情景中,低生态风险区面积增加最多,经济优先和自然发展两种情境下发展趋势较为一致.

       

      Abstract: The study area encompasses 20 county-level administrative regions within the Sichuan section of the Giant Panda National Park. Land use change data from 2000, 2008, 2016, and 2023 to analyze the spatiotemporal evolution of land use over 23 years and calculate the regional landscape ecological risk index. This study investigates the spatiotemporal differentiation and spatial autocorrelation of the landscape ecological risk index within the study area. Additionally, it employs the PLUS model to predict land use changes under three scenarios for the study area by 2030, thereby reflecting the spatial distribution of landscape ecological risks. The results indicate that: (1) From 2000 to 2023, forest land was the dominant land use type in the study area and showed an increasing trend, followed by grassland and cultivated land; (2) During 2000-2023, the overall landscape ecological risk index of the study area was relatively low, with low and relatively low ecological risk zones widely distributed spatially; (3) The global Moran’s I was significantly positive from 2000 to 2023, and local spatial clustering characteristics were mainly dominated by high-high and low-low aggregation; (4) Under the three scenarios of economic priority, ecological protection, and natural development in 2030, the spatial distribution of landscape ecological risks follows historical patterns. In the ecological protection scenario, the area of low ecological risk zones increases the most, while the trends under economic priority and natural development scenarios are relatively consistent.
