摘要:

通过对县域农业结构优化问题的研究,提出了基于遗传算法的县域农业结构优化方法,建立了机会约束规划模型;以北京市通州区为例,对模型进行了求解,得出优化结果,并对通州区农业用地结构调整提出了建议。

关键词: 农业结构, 遗传算法, 优化

Abstract:

A county-scale agricultural structure (CSAS) optimizing method based on genetics algorithm was developed in the paper.An opportunity constrained programming model was built based on the algorithm and applied in agricultural land restructuring in Tongshou District,Beijing. An optimization result was derived from the model,and an optimization solution of landuse restructuring was given.

Key words: agricultural structure, genetic algorithm, optimization
