基于低碳经济导向的土地利用结构优化研究——以福建省福州市为例

目的]研究基于低碳经济导向的福州市土地利用结构优化方案,为相关部门进行土地利用规划及其调整提供参考。方法]采用灰色多目标线性规划法,建立目标函数,获得土地利用结构优化方案。结果]通过与土地规划方案对比发现,中碳排放型的的优化方案最佳。在该方案下,预计到2020年福州市土地碳排放量达1.30×107 t,土地经济效益为7 701.24亿元,土地生态效益为785.33亿元。结论]低碳经济导向的土地利用结构优化方案有利于该区域经济效益的发挥和生态环境的改善,实现碳减排目标。

Optimization Research of Low-carbon Economy Oriented Land Use Structure -A Case Study in Fuzhou City of Fujian Province

Objective] Exploring the optimization of low-carbon economy oriented land use structure to provide support for government land use planning and adjustment.Methods] The best land use structure program was carried out by adopting gray multi-objective linear programming method to establish an objective function.Results] In reference with land use planning scheme, we found that the medium carbon emission scheme in Fuzhou City is the best land use structure program. This medium carbon emission scheme was predicted that can decrease carbon emissions as much as 1.30×10⁷ t, increase economic benefits as high as 7.70×10¹¹ yuan and increase ecological benefits as high as 7.85×10¹⁰ yuan by 2020.Conclusion] The low-carbon economy oriented land use structure would be in favour of the regional economic benefits and ecological environment improvement, which can reach the carbon reduction target.
