Study On Energy Flowing Regulation Of Farming And Meat Goat Raising Ecosystem Of Farmer Household In Yaozhou District, Tongchuan City

The energy flowing regulation of farming and meat goat ecosystem was studied through investigating resources status of population,family,farming and animal raising of 206 farm households who inhabit in some administration villages of Xiaoqiu county,Guanzhuang county and Zhaojin county,Yaozhou district,Tongchuan City in 2003, and through surveying the amount of diet and dejecta when different feeds were fed to local nursing ewe,male boer goat, male boer goat cross bred nursing ewe and male boer goat cross bred young ewe in Jinsheng Ecological Goat Breeding Demonstrate Base,Yaozhou District,Tongchuan City.The results are listed as follow:1. The average amount of total artificial auxiliary energy inputing to farming sub-system in Yaozhou district was 42.35×10~3 MJ per household,it was lower; the amount of energy output from farming sub-system reached 110.95MJ,the input-output ratio of farming sub-system reached 2.62.The amount of total artificial auxiliary energy inputing to animal raising sub-system was 76618.70MJ per household.The amount of output energy of animal raising sub-system was 24448.07MJ.The energy transformation efficiency of feed which reached 0.32 was low. Eespecially the amount of input energy of cattal raisinging system reached 67197.45MJ, and the amount of output energy of cattal raising system reached 19958.50MJ, the energy transformation efficiency of feed reach 0.30. The amount of energy input to goat raising system reached 9421.25MJ, and the amount of output energy of goat raising system reached 4489.58MJ. The energy transformation efficiency of feed reached 0.46.2. The utilization efficiency of solar energy of crops in research area were 0.26(wheat), 1.16(maize), 0.14(rape) and 0.32(alfalfa) respectively, and were lower than the mean level of whole country except the maize.3. The artificial auxiliary energy input to farming sub-system of the large, medium, small scale farm households reached 35.04×10~3 MJ, 51.48×10~3 MJ and 84.49×10~3 MJ respectively after the farming industry structure was adjusted.The energy output from farming sub-system of the large, medium, small scale farm households reached 310.89×10~3MJ,185.40×10~3MJ, 118.81×10~3 MJ respectively. The energy output-input ratio of farming sub-system of the large, medium, small scale farm households reached 3.39, 3.60 and...
