摘　　要：国家级森林公园具有丰富的自然资源与重要的生态功能,是生态安全屏障和生态文化遗产的重要载体。定量评价国家级森林公园生态系统健康,有助于促进生态文明建设和可持续发展。以湖南雪峰山国家森林公园为例,利用长时间序列的遥感影像数据,系统分析研究区的生态用地景观格局变化规律,并对其生态系统健康进行评价。结果表明:(1)2011—2022年,研究区的土地利用变化以耕地和建设用地增加,林地、草地和水域减少为主。(2)生态系统结构整体呈增长趋势,表明生态系统的整体结构相对稳定,在空间分布上存在一定的异质性,低值地区的生态系统结构较为单一。(3)生态系统功能整体呈现微弱减少的趋势,而50.91%的地区表现增长趋势,表明研究区的生态系统功能在大多数地区仍有所提高。(4)研究区的生态系统健康整体呈增长趋势,在空间上呈现明显的空间异质性,高值地区主要分布在雪峰山中段的苏宝顶北部和东部区域,而低值地区主要集中在雪峰山主中段的高海拔地区。研究结果能为该区域制定科学合理的生态保护政策提供良好的数据支撑和决策依据。National forest parks are endowed with abundant natural resources and serve as crucial bastions for ecological security and supports of ecological and cultural heritage.A quantitative assessment of the ecosystem health of these national treasures is instrumental in propelling the development of ecological civilization and fostering the sustainable progress.Taking the Hunan Xuefeng Mountain National Forest Park as a paradigm,this study uses extensive time-series remote sensing data to meticulously analyze the spatio-temporal nuances of land use and landscape transformations in the researched areas.Furthermore,it delivers a comprehensive evaluation of the ecosystem s overall health.The results indicate as follows.(1)From 2011 to 2022,the landscape witnessed an upswing in the cultivated and construction lands,whereas forested areas,grasslands,and water bodies experienced a notable decline.(2)The overarching structure of the ecosystem exhibited a discernible growth trajectory,signaling a degree of stability in the system s structural integrity,albeit with some spatial heterogeneity.Notably,ecosystem structures in regions with lower values tended toward a more homogeneous composition.(3)The comprehensive functionality of the ecosystem demonstrated a subtle declining trend,with a noteworthy 50.91%of areas showcasing an upward trajectory.This suggests an overarching enhancement in the ecosystem s functionality across most regions.(4)The overall health of the ecosystem in the studied areas portrayed an upward trajectory,underscored by the marked spatial heterogeneity.Regions with higher values were predominantly situated in the northern and eastern sectors of Subao Peak in the middle section of Xuefeng Mountain,while lower-value areas were concentrated in the high-altitude regions of the primary middle section of Xuefeng Mountain.The research outcomes furnish substantive data support and a scholarly decision-making framework for the formulation of scientifically rigorous ecological conservation policies within the design
