Abstract: Characteristics of energy flow in a Xian eco-animal breeding model in Dawa county of Liaoning province were analyzed based on the study of mass cycling. Photo-utilization efficiency of crops and conversion ratio of energy as well as the status and tole of organic manure energy input in the agroecosystem were analyzed.

Key words: climate change, city carbon emission, time series analysis, factor decomposition analysis, STIRPAT model.
