The energy input from human

animal and machines in soil preparation

planting cultivation and management and cutting

etc.to 5 kinds of shrubs and 4 of trees were calculated

then the comparison of energy input with output of standing trees and/or fuel wood was conducted. The production of Astragalus adsurgens Pall.

Medicago sativa L.

Onobrychis visiaefolis Scop was analysed

in energy input through human labour and seed and energy output through grass

fuel and seed. The energy input to animals through raise and management and their output of energy through animal power

young animal

eggs and excrement of animals were calculated. Having studied energy output with energy input structure of the animals

a systematic analysis to energy flow for the sub-system of animal husbandry was made. It is suggested to develop the number of sheep and cattlas but limit and decrease the number of rabbit and chikens.
