摘 要:利用改进后的生态占用模型,计算了2003—2017年南宁市人均生态占用、2011—2017年人均生态承载力,并基于资源环境承载力视角采取相关生态占用影响因素建立指标体系,利用灰色关联度确定各因素的影响程度以对南宁市资源环境承载力状况进行评价。结果表明:南宁市人均生态足迹从2003年的1.3006 hm 2/cap增加到2017年的1.8861 hm 2/cap,增幅为45.02%,南宁市人均生态承载力由2011年的0.7192 hm 2/cap下降到2017年的0.6617 hm 2/cap,减少0.0575 hm 2/cap,降幅为7.99%,资源环境承载力严重不足,区域可持续发展形式严峻,总人口数、城镇人口、建成区面积对南宁市的生态占用有深远影响。调整产业结构以及控制城镇人口增长是提高资源环境承载力,实现南宁市可持续发展的有效途径。This paper uses the improved ecological occupancy model to calculate the ecological occupancy per capita in Nanning from 2003 to 2017,and the ecological carrying capacity per capita from 2011 to 2017.Based on the perspective of resource and environmental carrying capacity,the relevant ecological occupancy factors are used to establish an indicator system and use gray correlation to determine the degree of influence of various factors to evaluate the status of Nanning’s resource and environmental carrying capacity.The results show that:During the study period,the per capita ecological footprint of Nanning increased from 1.3006 hm 2/cap in 2003 to 1.8861 hm 2/cap in 2017,an increase of 45.02%.The ecological carrying capacity per capita in Nanning decreased from 0.7192 hm 2/cap in 2011 to 0.6617 hm 2/cap in 2017.reduced 0.0575 hm 2/cap,a decrease of 7.99%,the resource and environmental carrying capacity is seriously insufficient,the regional sustainable development form is severe,and the total population,urban population,and built-up area have a profound impact on Nanning’s ecological footprint influences.Adjusting the industrial structure and controlling urban population growth are effective ways to improve the carrying capacity of resources and the environment and achieve sustainable development in Nanning.
