Abstract: 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. 

Key words: new input and output model, linear programming, radiant ecological engineering
