摘　　要：本文将基于遥感反演的植被净初级生产力(NPP)的均衡因子和产量因子评估方法引进到三维生态足迹模型中,利用足迹广度和足迹深度两个指标,以“国家公顷”为计量单位,从空间和时间两个角度计算并分析了桂林市2000年、2005年、2010年、2015年和2018年的生态承载力和资源环境的可持续发展能力;同时,利用经济评价指标(GDP)和生态足迹指标,定量评估了桂林市自然资源利用效率。结果表明:2000—2018年桂林市的生态承载力略微增加,生态足迹和生态赤字均呈现出一致的先增加(峰值在2010年)后下降趋势;各土地利用类型对人均生态足迹和人均生态承载力的贡献率有较大的差异,社会经济建设中各类土地的需求和供应水平不对等。足迹广度除2005年稍有下降外,其余年份基本呈现出增长趋势,而足迹深度则呈现出先增长后下降的趋势,自然资源过度消耗是影响桂林市生态环境可持续发展的重要因素。2000—2018年桂林市自然资源利用效率显著提高,2010年以后第三产业逐渐在经济建设中占主要地位,经济发展潜力较大。In this paper,we introduced the evaluation method of balance indicator and production indicator based on satellite retrieved net primarily production of vegetation that is implemented into a three-dimensional ecological footprint model.Using this model,we further calculated and analyzed the ecological carrying capacity and sustainable development ability of resources and environment in 2000,2005,2010,2015,and 2018 in Guilin from the perspectives of space and time,using footprint breadth and footprint depth as the measurement unit and"national hectare".In addition,the utilization efficiency of natural resources in Guilin was quantitatively evaluated using the economic evaluation index(Gross Domestic Product,GDP)and ecological footprint index.The results showed that the ecological carrying capacity in Guilin increases slightly from 2000 to 2018,while the ecological footprint and ecological deficit both increase at first with the peak values appearing in 2010 and then decrease.Contribution rates of various land-use types to the per capita ecological footprint and ecological carrying capacity are quite different,and the demand and supply levels of all kinds of land in social and economic construction are unequal.The footprint breadth increases in all years except for 2005,and the footprint depth increases first and then decreases.The excessive consumption of natural resources is an important factor affecting the sustainable development of the ecological environment in Guilin.The ecological efficiency of natural resources in Guilin increases significantly from 2000 to 2018.After 2010,the tertiary industry gradually plays a major role in economic construction,with great economic development potential.
