东台市复合农林业产业结构的优化

Studies on the Optimization of Structure of Agroforestry in Dongtai City

以江苏省东台市为例 ,运用灰色线性规划的方法对优化复合农林业的产业结构进行了研究 ,结果表明 :种植业面积减少了 2 83%,而产值增加了 1 6 4 6%;林业面积增加了 2 4 2 %,产值增加了 47 53%,森林覆盖率由 2 0 2 %增加到 2 5%;畜牧业产值增加了 8 9%。土地复种面积比对照增加了 0 4 9%,净产值增加了 1 4 58%。种植业、林业、渔业面积比由原来的 1 7∶4 2∶1调优到 1 4 6∶4 8∶1 ;农、林、牧、渔净产值比由原来的 7 1∶1∶6 5∶1 7调优到 5 6∶1∶4 9∶1 2。

By the use the theory of grey linear programming,we reformed the optimization of structure of agroforestry in Dongtai City.The research results showed that:The total planted land area increased 0.49% and the net financial income increased 14.58%;Planting area decreased 2.83% and the financial income increased 16.46%;Forest area increased 24.2%,economic income increased 47.53% and the rate of cover forestry increased from 20.2% to 25.0% ;The animal husbandry income increased 8.9% and the fresh-water raise industry was equal to the average years.The plantation of plant,forest and fish raising area optimizated from 17∶4 2∶1 to 14.6∶4.8∶1;The net income of farming,forest,animal husbandry and fish raising optimiaxted from 7.1∶1∶6.5∶1.7 to 5.6∶1∶4.9∶1.2.It can provide the fundamental basis to the system.
