以甘肃省民勤治沙综合试验站区域为系统,应用线性规划的方法,建立区域生态经济型系统的优化模式。结果表明,区域系统在现有的生产条件及生产力水平下,要达到最大经济效益,并保证区域系统的生态趋于良性循环,其农林牧三业用地的最优比例为1∶9.5∶9.5,此时区域系统的经济纯收入最大,为113.72万元,年人均纯收入达5686元。
Taking the area of Minqin Sand Control Comprehensive Experimental Station of Gansu Province as a system, a linear programming method was used to establish the optimization mode of regional eco-economic system. The results show that under the existing conditions of production and productivity, the regional system should reach the maximum economic benefit and ensure that the ecological system of the regional system tends to a virtuous cycle. The optimal ratio of the agricultural, forestry, animal husbandry and husbandry industries is 1: 9.5: 9.5. At this moment, the largest net economic income of the regional system was 1.1372 million yuan, with a per capita net income of 5,686 yuan.
