Abstract:

Using China's advanced eco-agricultural model for Baiquan County, Heilongjiang Province, extensive statistical data and original information were collected. Based on dynamic analyses of economic features of the agricultural system and ecological restoration and rehabilitation, the Emergy theory was used to study production efficiency and sustainable developmental dynamics of the agricultural eco-economic system in an ecological rehabilitation time series (1980-2000). The objectives were to explore the research concept on quantification of agricultural effects of regional ecological restoration and rehabilitation, and to provide a scientific basis for planning of harmonious socio-economic development in this and similar regions. The results show great achievements in economic development and ecological reconstruction of the county. The production and living environments have also been significantly improved, but there is still environmental pressure on the agricultural system itself: production efficiency of the county's agriculture and farmers' living standards are still low. However, large-scale ecological restoration and rehabilitation has yielded some agricultural improvements, and the Emergy of the system is now better in terms of sustainable development.
