钱江源国家公园景观格局变化探析

Changes of Landscape Pattern in Qianjiangyuan National Park

  • 摘要: 从景观水平和类型水平两方面选取了斑块数量、斑块密度、最大斑块指数、景观形状指数、景观分散指数、蔓延度指数、香农多样性指数7个景观格局指数,分析2019年和2021年钱江源国家公园的景观空间分布特征及其动态变化。结果表明:(1)在土地利用变化方面,钱江源国家公园以林地和园地为主,占公园总面积的92%以上;与2019年相比,2021年各类土地利用类型变化不大,面积增加最多的是林地,面积减少最多的是耕地,森林覆盖率稳步增加,在一定程度上反映了园区在林业生态建设上所取得的成效;(2)在景观格局演变方面,2019年和2021年景观类型尺度和景观水平尺度的指数变化情况反映出园区内景观异质性趋缓,逐渐向优势景观均质化、整体化发展,且各类景观的交错分割现象得到一定程度的改善,有利于生态功能和生态系统稳定性的发挥。

     

    Abstract: Based on land cover data in 2019 and 2021 in Qianjiangyuan National Park, Zhejiang province, landscape pattern and dynamic changes was analyzed in terms of landscape levels and types. The results show that woodland and garden accounted for more than 92% of the total area of the park. Compared with 2019, there was little change in types of land use in 2021. The area of woodland increased the most while the area of cultivated land decreased the most. In terms of landscape type and level in 2019 and 2021, their changes reflected the easing of landscape heterogeneity, and development towards landscape homogenization and integration, and improvement of different landscape segmentation.
