摘　　要：为了探讨湖南省张家界市各类土地生态安全及其空间格局,基于生态足迹分析,计算张家界市2000年、2005年、2010年、2015年、2020年5期土地生态足迹、生态承载力、生态盈亏和生态压力指数,并通过建立土地生态安全评价模型,依据标准化生态压力指数评判张家界市土地生态安全等级。结果表明,2000—2020年张家界市人均生态足迹呈上升趋势,增长了52.4%;人均生态承载力基本保持稳定;生态赤字增长了1.45倍;生态压力指数亦上升,增长了52.2%。张家界市土地生态安全呈波动变化,总体处于不安全状态,土地生态安全空间格局表现为不安全区域与草地和水域重叠,安全区域与林地重叠。In order to explore the ecological security and spatial pattern of various types of land in Zhangjiajie City,Hunan Province,based on the ecological footprint analysis,the land ecological footprint,ecological carrying capacity,ecological profit and loss,and ecological pressure index of Zhangjiajie City in five periods of 2000,2005,2010,2015 and 2020 were calculated.Through the establishment of the land ecological security evaluation model,the grade of land ecological security in Zhangjiajie City was evaluated according to the standardized ecological pressure index.The results showed that the ecological footprint per capita of Zhangjiajie City showed an upward trend from 2000 to 2020,with a growth rate of 52.4%;the ecological carrying capacity per capita remained basically stable;the ecological deficit had increased by 1.45 times;the ecological pressure index also increased by 52.2%.The land ecological security in Zhangjiajie City fluctuated,and was generally in an unsafe state.The spatial pattern of land ecological security showed that the unsafe area overlapped with the grassland and water area,and the safe area overlapped with the forest land.
