Abstract:
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.
