摘要
以湖南省邵阳市城步苗族自治县南山国家公园1990年至2019年间约10年为一期的遥感影像数据为基础,利用土地转移矩阵模型及景观格局指数等方法,分析近30年间南山国家公园土地利用变化、景观格局动态变化。结果表明;1990—2019年间南山国家公园景观格局变化,总体表现在:林地、水域和建设用地面积的增加,其他用地、草地和耕地面积的减少。景观水平上总体而言,景观破碎度呈下降趋势;景观的多样性相对减少;1990年至2019年间始终是林地作为优势斑块占据主导地位,且优势度基本不变;国家公园政策的出台之后,研究区生态环境有所改善,生态环境受人为干扰影响程度减弱。
Based on the remote sensing image data of Nanshan National Park in Chengbu Miao Autonomous County,Shaoyang City,Hunan Province from 1990 to 2019,land transfer matrix model and landscape pattern index were used to analyze the land use change and landscape pattern dynamic change in Nanshan National Park in recent 30 years.The results show that the change of landscape pattern in Nanshan National Park between 1990 and 2019 is mainly reflected in the increase of forest land,water and construction land,and the decrease of other land,grassland and cultivated land.On the whole,the degree of landscape fragmentation is on the rise,the diversity of landscape is relatively reduced,from 1990 to 2019,it is always forest land as the dominant position of the dominant spot,and the degree of advantage is basically unchanged,after the introduction of the national park policy,the ecological environment of the research area has improved,and the degree of influence of the ecological environment by man-made interference has decreased.
