An assessment system for sustainability in the greenhouse viticulture was developed based on the database technology, network technology and emergy analysis theory. Firstly, a complex analysis on production process of greenhouse viticulture was conducted and a model to assess sustainability based on emergy was proposed. Then, the data from Changli county was acquired to test the system. Results showed that the system could assess the sustainability of the greenhouse viticulture system effectively, and identified the key factor in sustainable development, as well as promoted the standardized management of plantation production and improved the capacity for sustainable development of greenhouse viticulture industry.
