| Abstract: | In order to enhance the well cycle of the farmland ecosystem in Liangzhou district,Wuwei City,we have studied its energy input and its utilization efficiency、input and output situation of nitrogen,phosphorous and potassium,and profit of value-transforming etc,and state their quantantive characteristics of material flow energy flow and value flow the results show: the farmers have basically realized mechanization and completed the transformation of traditional agriculture to modern agriculture.We point out the problems in the farmland producing and how to solve them. |
