The energy survey of two-harvests-a-year protected viticulture has a strong and typical significance, but traditional energy consumption analysis has some drawbacks: complicated artificial calculation, long period and low data quality. Aiming at solving above problems, an energy consumption evaluation system for two-harvests-a-year protected viticulture was developed based on MVC (mode, view, and controller) framework, B/S (browser/server) structure and Matlab Builder JA function. Firstly, a complex analysis of production process of two-harvest-a-year protected viticulture was conducted, an energy input and output system was established, and an energy efficiency evaluation model combined with DEA-BCC model and Malmquist index method was proposed. The model based on the input-oriented DEA-BCC model, through the three parameters: technical efficiency, pure technical efficiency and scale efficiency, to evaluate energy efficiency. At the same time, obtaining technical efficiency change, technical progress and scale efficiency change by Malmquist index decomposition, and conduct a comprehensive assessment of energy efficiency through the above two aspects.Then, the data from Guangxi province was chosen to test the system. Results showed that the system improved the computational efficiency, and can meet the needs of different users, as well as provided reliable data processing support for the study of energy consumption in two-harvests-a-year protected viticulture.
