本文从生态经济效益出发,根据林业区域特征和林种的地类适宜性原则,应用系统动力学和线性规划模型制定了黄土高原地区中长期林业发展战略规模和林种布局的优化方案,到2030年,有林地将达到26343万亩,覆盖率28.0%,蓄积量46698万m~3,果品1179万吨,林业产值96.35亿元(比1985年提高6.2倍)。人均用材0.11m~3,果品82公斤,粮食350公斤,农户薪柴653公斤,水土流失减少27.1%。这样既满足了社会发展需求,又充分发挥了各地的资源优势。
Based on the characteristics of forestry and the suitability of land for forest species, this paper developed the optimal plan for the medium and long-term forestry development scale and forest layout in the Loess Plateau by applying the system dynamics and linear programming model. By 2030 In the year, there will be 26.343 million mu of forest land, with a coverage rate of 28.0%, a volume of 466.98 million m 3, an output of 11.79 million tons of fruit and a forestry output value of 9.635 billion yuan (6.2 times higher than in 1985). Per capita timber 0.11m ~ 3, fruit 82 kilograms, food 350 kilograms, farmers 653 kilograms of fuelwood, soil erosion decreased 27.1%. This will not only meet the needs of social development, but also give full play to the advantages of resources all over the world.
