基于村庄规划的土地利用结构优化——以湛江市群井村为例

Optimization of village land use structure based on village planning:A case study of Qunjing village in Zhanjiang city

在“多规合一”的背景下,基于2019年土地利用数据,采用灰色多目标线性规划模型优化2025年湛江市群井村土地利用结构。综合考虑经济、生态和社会效益目标,建立了群井村2025年土地利用结构优化模型。结果表明,在经济效益最大化的方案下,建设用地增加了33.72%,达到3种方案中的最高值;在生态效益最大化的方案下,群井村生态用地变化最明显,增加了108.59%;在社会效益最大化的方案下,农业、建设和生态用地发展较为均衡,趋于最优的群井村土地利用结构优化方案。应用灰色多目标线性规划模型优化群井村土地利用结构,比上级规划下达的硬性指标更科学合理,优化结果的各项约束性指标更有利于推动美丽生态乡村建设。

Under the background of“Multiple Planning Integration”,based on 2019 land use data,the grey multi-objective linear programming model was used to optimize the land use structure of Qunjing village in Zhanjiang city in 2025,which was developed to optimize the land use structure of Qunjing village in 2025. Taking into account the economic,ecological and social benefits,the land use structure optimization model of Qunjing village in 2025 was established. The results showed that,under the scheme of maximizing economic benefits,construction land increased by 33.72%,reaching the highest value of three schemes. Under the scheme of maximizing ecological benefits,the change of ecological land in Qunjing village was the most obvious,with an increase of 108.59%. Under the scheme of maximizing social benefits,the development of agriculture,construction and ecological land were more balanced,and the land use structure of Qunjing village was an optimized project. The application of the grey multi-objective linear programming model to optimize the land use structure of Qunjing village is more scientific and reasonable than the rigid indicators issued by the superior planning,and the constraint indicators of the optimization results are more conducive to promoting the construction of beautiful ecological countryside.
