【摘要】 生态足迹法是用于评价区域发展可持续性的重要方法。以四川省地震重灾区绵阳市为例,计算了2000—2009年生态足迹和生态承载力。结果表明,该区人均生态足迹呈波动式增长,由2000年的1.377 2hm2增长到2009年的2.408 7hm2;人均生态承载力增长缓慢,人均生态赤字由0.954 4hm2增长到1.922 0hm2;生态压力指数由3.257 6增长到4.949 3;万元GDP生态足迹由2.252 1下降到1.599 6;2008年"5.12"汶川地震后,生态足迹出现急剧增长。随着近年来绵阳市资源消耗增加,发展模式呈不可持续状态,社会经济发展与生态环境的协调性较差。为实现生态城市建设规划目标和可持续发展战略,建议适当控制人口增量,调整农业产业结构,保护耕地资源,转变人们的生活和生产方式。更多还原

【Abstract】 Ecological footprint(EF)is one of the most important methods to evaluate the sustainability of region development.The ecological footprints and ecological capacity(EC)were calculated based on the ecological footprint theory and model for Mianyang City during 2000to 2009.The results show that within the study period,the ecological footprint per capita increased,with apparent fluctuations,from 1.377 2hm2 to 2.408 7hm2,the ecological deficit per capita increased sharply from 0.954 4hm2 to 1.922 0hm2,and the ecological capacity per capita increased only slightly.In contrast,the ecological tension index arose from 3.257 6 to 4.949 3,and the ecological footprint of ten thousand Yuan GDP decreased from 2.252 1hm2 to 1.599 6 hm2.Especially,the ecological footprints and ecological deficits showed sharp growth since the reconstruction after the"5.12" Wenchuan earthquake in 2008.With increasing consumptions of natural resources in Mianyang City,the conflicts between ecological footprint and ecological capacity were amplified;suggesting an unsustainable state of the present developing model and poor harmony between socioeconomic development and ecological environment.In order to achieve the goals of eco-city construction plan and sustainable development strategy in Mianyang City,recommendations were made based on the analysis of this study,including controlling the size of population,adjusting the structure of agricultural industry,protecting the resources of cultivated land,and optimizing life style and production mode of the people.更多还原
