采用多目标线性规划原理,对本地区生态农业建设模式进行优化,得出:示范区人均收入达1 643元,可利用饲草总产量9 538 965 kg,人均占有粮食500 kg。土地侵蚀模数由2000年的7 800 t/km2降低到2 120 t/km2。农林牧用地比例调整为3∶3∶4。通过综合治理措施,随着森林覆盖度不断扩大,林龄增大,林木生长旺盛,示范区农林牧副结构更加合理,生态经济社会效益更加突出。生态环境进一步恢复,示范区必将走向资源、环境、人口、经济、社会协调持续发展的道路。
Using the multi-objective linear programming principle, the eco-agricultural construction pattern in this area is optimized. The result shows that the per capita income in the demonstration area reaches 1 643 yuan, the available forage grass output is 9 538 965 kg and the per capita grain is 500 kg. The modulus of land erosion decreased from 7 800 t / km2 in 2000 to 2 120 t / km2. Agriculture, forestry and animal husbandry land ratio adjusted to 3: 3: 4. Through comprehensive control measures, with the continuous expansion of forest coverage, increasing age, vigorous growth of forest trees, the structure of agriculture, woods, pastoral and animal husbandry in the demonstration zone is more reasonable and the ecological, economic and social benefits are more prominent. With the further restoration of the ecological environment, the demonstration area will surely move towards the road of coordinated development of resources, environment, population, economy and society.
