基于生态足迹模型的威远县2016~2020年可持续发展的路径分析

Path analysis of sustainable development in Weiyuan County from 2016 to 2020 based on ecological footprint model

以内江市西北部威远县为探讨对象,对内江市2016~2020年统计年鉴数据进行分析整理,利用生态足迹模型来评估威远县近五年可持续发展的情况.通过分析表明:(1)威远县2016~2020年的发展情况均出现生态赤字现象,2017年表现为最高,达到-1.034 hm^(2)/人;(2)威远县各土地类型生态足迹需求和生态供给情况分不均衡,其中林地-0.028 hm^(2)/人、化石燃料地-4.9188 hm^(2)/人、水域-0.0836 hm^(2)/人和建筑用地土地-0.498 hm^(2)/人均为生态赤字,其中化石燃料地占比达到89%,耕地1.1171 hm^(2)/人和草地0.106 hm^(2)/人表现为生态盈余.为了威远县能持续的走可持续发展路线,用生态足迹模型进行分析当地情况,为当地发展提供了一定的理论基础.

Taking Weiyuan County in the northwest of Neijiang City,Sichuan Province,China,as the object of discussion,the statistical yearbook data of Neijiang City from 2016 to 2020 were analyzed and sorted,and the ecological footprint model was used to evaluate the sustainable development of Weiyuan County in recent five years.The analysis showed that the ecological deficit phenomenon occurred in Weiyuan County from 2016 to 2020,and it was the highest in 2017,reaching-1.034 hm^(2),and that the ecological footprint demand and ecological supply of different land types in Weiyuan County were not balanced:the ecological deficit of forest land was-0.028 hm^(2)/person,fossil fuel land-4.918 8 hm^(2)/person,the water area-0.083 6 hm^(2)/person,and building land-0.498 hm^(2)/person,among which fossil fuel land accounted for 89%,and the ecological surplus of arable land was 1.117 1 hm^(2)/person and grassland was 0.106 hm^(2)/person.To achieve a sustainable development in Weiyuan County,the ecological footprint model was used to analyze the local situation,which provides a certain theoretical basis for local development.
