Abstract: This paper summarizes and analyzes all-sidedly the inputs and outputs of the matter, energy and capital from 1985 to 193Ton Guquan Experimental Farm of Ecological Engineering.The total output Value of the Experimental Farm over three years has reached 1 518 000 yuan RMB with a profit of 260 100 yuan RMB, It has provided markets with 490 000 kg of meats, including chickens, pork pigs, fish and so on. It will take only four years to recoup the farm’ s capital outlay. The analysis shows that the conversion rates of energy and nitrogen on the farm are 15.2% and 40% respectively, that the energy conversion rate can be increased by 2.7% and the use rate of nitrogen can be raised by at least 6% through using integratedly 81.8% of the internal trash or waste, and that the output value, profit and the conversion rates of energy and nitrogen have increased year by year. So, the authors suggest that the experiences of Guquan Experimental Farm should be popularized in the suburbs of cities and the countrysides with local conditions.
