Abstract:: The initial analysis about the energy inputs and emergy outputs of plantation ecosystem from the perspective of energy in immigrator area of Hongsibu, the representative area of Ningxia immigrator area was carried out based on the statistical and survey data of 2007 in this area. The evaluation index system consisting of environmental load ratio, the net emergy yield ratio, emergy investment ratio, and sustainable development index was established. Compared with the similar area and some developmental areas, the analysis showed that the investment of energy in this area was mainly from the non-renewable industrial auxiliary energy, especial fertilizer. The comparatively lower ratio of energy investment and the net energy yield, and higher load ratio of environmental caused great pressure on the environment. The low index of sustainable development in this plantation belongs to consumer-oriented economic system. Based on the above characteristic of energy analysis of this area, the paper puts forward the strategies and suggestions for promoting the sustainable development of system.
