东台市沿海农区农业生态经济系统结构优化研究

Studies on the structure optimization of agro ecological and economic system in Dongtai coastal area

以江苏东台市为例 ,运用灰色线性规划的方法对沿海农区农业生态经济系统结构进行优化。结果表明 :通过土地利用结构的调整优化 ,农林牧渔各业结构更趋合理 ;经济效益有显著增加 ,优化方案的农业净产值为 11 0亿元 ,比对照增长 14 5 8% ;优化方案将进一步改善农业生态环境 ,可获得比较明显的生态社会效益。

Grey linear programming was used to optimize the structure of agro ecological and economic system in Dongtai coastal farmland.The results showed that the structure of agriculture,forestry,animal husbandry and fishery would be more rational and more economically efficient than before.Compared with the average from 1995 to 1997,the net value of agricultural output in the optimized program would be increased by 14 58% with 1 100 million yuan.With the program,the agro ecological environment would be improved and substantial ecological and social benefits would be achieved.
