辐射型生态工程结构优化研究

本文根据辐射型生态工程——星火养殖场的生产情况,建立新型投入产出模型,结合线性规划模型,对系统结构进行综合评价和优化设计。模式Ⅰ优化结果,利润最大值41万元,是实际值的4倍;模式Ⅱ的最优结构与模式Ⅰ的相同,利润最大值77万元。结果表明,充分利用系统设施和不断采用新技术是取得最佳效益的两个重要方面。

STUDY ON THE OPTIMAL STRUCTURE OF RADEANT ECOLOGICAL ENGINEERING.

A new input-output meclel , combined with linear programming, was applied to forecast and optimize the production structure of radiant agro-eco-engineering on the basis of production situation of Xinghuo Experimental Husbandry Farm in 1989. The: main results are as follows; the optimized profit value of optimum production structure of the year 1989 was 412642 yaun, which was 3. 98 times of real production structure in the same year. However, with another model. the optimized profit value of the forecast production was 776108. 8 yuan, though its structure was similar to the optimized production strucfute of 1989, It is suggested that fully utilization of the facilities in the farm and application of new techniques are two important aspects for obtaining optimal effects.
